It's been a while (I know I'm late ...) but Hyperstar have some serious specs with V4 that we need to talk about.
I love my RASA 11 though and missing shooting in F2.2 !
Hopefully this video helps you choose what's right for you.

Thank you so much for the shoutout Dylan! The RASA system is incredible - it truly gives a wow moment when you first stretch a stacked image and see how much data-rich signal is captured, and when you find faint, intricate details normally hidden. Cheers mate!

@siberx4 Месяц назад

For anybody who didn't understand the point about filters, when you have your camera mounted to the front of the telescope, the diameter is a big issue. If your camera and whatever is bolted to it is much wider than the central obstruction, then you're losing light. There's not enough space to install a full filter wheel in front of the camera without blocking most of the telescope's front glass, but you can get away with a single-filter drawer because it's usually smaller than the big astrophotography cameras. This means you can't automatically change filters, which really limits your options if you want things fully hands-off and automated.

Little tip for helping to get the lid back on a Celestron telescope: I put little colour-coded sticky dots on the lid and on the rim of the scope to show where the two match up. Makes putting the lid on much much easier!

@richardkelsch3840 Месяц назад

Excellent discussion, Dylan! I have a C14 OTA which I bought about 35 years ago, but never used much for imaging. That changed when Hyperstar first became available. I love using it now, both because of the 700mm focal length and the f/2 speed. It's mounted permanently in a 4m dome that my wife and I built 40 years ago. When I retired, we started wintering in Arizona, away from our home north of Toronto, taking the 14 was not an option, and I went with a variety of different smaller scopes. Until the RASA 8 became available. That is what we've been using, and love it. Some of our best images have been taken with it. It's a breeze to use and light enough for my octogenarian self to handle easily. My conclusion is that I enjoy both, and I agree with the points you have made. Clear skies, Rick

@marshawilcox Месяц назад

Clear and informative, as always, Dylan. Thanks! True confessions (with a little embarrassment), careful as I was, … I dropped the secondary while putting on the Hyperstar. It was disheartening. Celestron was wonderful, but the repair took a long time. I now have a C11 and RASA 11, both on JMI wheelies. Foot-powered automation - I roll them out of my garage to marked spots on my driveway to image. The focal lengths are slightly different. The FoV is just a little wider with the Hyperstar v4- 540mm vs 620mm - not enough for me to put the Hyperstar back on, yet. That day may come. Thanks for all you do for the community.

I've been debating this for a while myself, as she has a C11HD setup and wants to get into photography. I was just looking at the RASA and thought "let's see if Dylan has covered this". Thanks man! For less than the RASA, I can get her the camera, Hyperstar and autofocuser. Now I have to obsess over the 1st camera.

@philipps3988 Месяц назад

Excellent video, as always! I can add a bit color: I do have a C14 plus the V4 Hyperstar for it and for some time I was wondering if I would be better off with having purchased a Rasa. But I could not find a single reason! Price wise - as far as I can tell - you get pretty close in both scenarios. But the flexibility you have !! It’s just wow! I did get a dedicated color camera for the Hyperstar (standard I shoot mono and use an EAF) but I now even went back to switch my mono camera to Hyperstar and got myself some fast Baader filters! Once you have your cabling figured out it is literally just: unscrew camera from back, but some cover on back, move camera to front and screw on Hyperstar and you are done! I got my cables completely prepared such that I literally just plug in and ready to roll..so: Hyperstar plus SCT all the way!

Great video Dylan, I almost just want to mention I'm really enjoying the vibe of the last few videos, nice and chill. I was recently gifted a C8, so hyperstar is a *very* attractive option as the total cost would be amazing for me with having to only buy the Hyperstar. I currently use an 8" newtonian so the wider option would be immense while also still being good for planetary.

@user-lt9py2pu6u Месяц назад

Another very interesting video Dylan, I don't own either of these scopes and I am not likely to in the near future but if I do get round to buying one I would probably go for the RASA simply because I would only use it on wide field targets anyway so wouldn't need the extra focal length.

Thanks for the review. It is good to hear from someone with years of experience working with the gear they are reviewing. I like the convenience of switching out the entire scope and train. I truly hate fiddling with finding the perfect 55mm back focus every time. Too much lost time, in my opinion. I have the C11, and when it comes time to take the plunge, I'll probably buy the RASA 11" and add a dedicated ZWO ASI2600 Monochrome Camera w/filters. What's another $7k or $8k? Keep up the good work!

I feel like I've spent a bunch on my setup while still trying to do it as economically as possible. Right - contradictory, I know.

So, for those of you who want to get into a really expensive hobby without it being really, REALLY expensive -- SCT with Hyperstar and then too many cameras, filters, adapters, and everything else.

@zara8289 Месяц назад

I originally started with a NexStar 8SE and got an EdgeHD 8 as an upgrade. Instead of selling the NexStar 8 I got a HyperStar 8 v4 for it. It's been amazing and works great. My understanding is the main difference between those two scopes is the secondary mirror quality and since the HyperStar replaces that by all appearances it works well and has just as much quality as the EdgeHD. HyperStar is a great option if you have a non-EdgeHD SCT or an older scope you want to upgrade and bring new life too. I love being able to do both wide and narrow field imaging now and that f/1.9 sucks in light so fast. Doing 5 minute subs with it blows my mind compared to my EdgeHD. I should say too the people at Starazonia are absolutely amazing and always there to answer any questions I have had in a timely manner with great insight.

@DylanODonnell Месяц назад

@cjuk81 Месяц назад

Been thinking the same thing myself with regards hyperstar, although currently i only have the 6"SCT with no hyperstar and a focal reducer. But with the cloudy UK weather im tempted by the hyperstar for the fast scope! However, ill loose my planet imaging abilities, so i might have to purchase a second scope for that :)

@cratervanawesome Месяц назад

I've got a v4 Hyperstar for my EdgeHd 8. It's been a challenging setup. Shooting that fast makes everything more important like backfocus and collimation. I've heard the larger ones like the c11 are much better as well since the image circle is larger. I'm not even using a large sensor (ASI183) and always felt like the image was never exactly right. I also felt like it wasn't wide enough to capture a lot of targets well, or framing had to be dead on. I haven't decided if i'll resell it or not, but i ended up getting a faster smaller scope (William Optics Pleiades 68) to feed my need for speed and wide field work and found it just way more trouble free. Not to mention Mono is so much easier without having to manually swap filters etc. I was lured in by the flexibility of having a wide-ish FOV at fast speeds and a longer focal length for galaxies and planets. Maybe if i had gone with a C11 I'd have a different opinion to the 8 setup, but i was limited by mount capacity.

@DylanODonnell Месяц назад

Good perspective there 👊🏼

@stevec.-desertskyobservato1925 Месяц назад

I've always been a Hyperstar guy. I first started with a CPC-800 and the Hyperstar was a good investment for my fork-mounted scope. Soon as I hit retirement, my dream was a C-11 or 14...I got a very nice (hardly used) C-11 with a CGEM-DX mount and a lot of extras for 3K (post COVID)....I purchased another Hyperstar for that unit and love it! They do sell a few different types of doo-dads for the diffraction spikes, not a big deal to me. But you make a great point and I'll chime in with one word to sum the Hyperstar up; "versatility." The Hyperstar is very versatile; one night it can be deep space, the next night planetary and the next visual (although I do very little visual). I'm lucky enough to live 100 miles or so from Starizona, the folks there are great and have helped me tremendously through the years. Great topic Dylan!

Since I don't have the luxury of an observatory in which would be a waste since I live under Bortle 9 skies, I have a portable rig for which the RASA 8" worked well for going to dark sites. Thanks to its speed and aperture, I could grab enough data in one night to make a decent SNR image. But now years of being a computer engineer and being active had ruined my joints and now I wish I had never sold my C6 Hyperstar setup which was very versatile. I am hoping Celestron makes their new RASA 6" available as an OTA option and hopefully it is lighter as the RASA 8" is a bit heavy. Thanks for the video and Clear Skies!

@mdnt_astro Месяц назад

Cool video, Dylan. This had been on my mind a lot lately. Just recently had my first taste of somewhat fast imaging with my Askar 103 and 0.6x reducer getting me down to f/4. I bought that scope over a RASA 8 because I wanted more reach and now I'm finding myself wanting more aperture at higher focal lengths and drooling over a RASA 11. I'm still shooting OSC (Bortle 3) and I'm kind of torn on what my next step is. The RASA would be much more expensive and I'd probably need new filters and accessories but curious if you think it would be more beneficial to keep going with OSC at f/2.2 or jump into a monochrome setup at f/7 & f/4.

I bought a HyperStar for my EdgeHD 8 but after a few months I ended up selling the HyperStar and buying a RASA 8. The main reason is that I was wanting to swap back-and-forth very often, but doing so was not as straight forward as they imply. Every time I swapped I'd need to recollimate, and that sucked. So now I have the EdgeHD 8 and the RASA 8 mounted side-by-side on the same mount in my observatory so swapping between them is as a easy as picking the appropriate profile in NINA.

quick question, what Mono camera do you use on your Edge 11? i can't find a camera that really hits the sweet spot between over and under sampled and Binning always looks worse to me.

@DylanODonnell Месяц назад

Yeh I’m oversampled with the c11 and qhy268m but I choose not to bin .. I dither, drizzle then downscale later before final sharpening just so I have the most detail / resolution in the data before I halve the resolution in post.

@MasseyLee Месяц назад

I had the same issue as you with wanting to automate the Rasa in monochrome. I designed a 4 filter changer for my Rasa 11 which fits in the (very small) space between the camera and the corrector plate. It works well, and I got some prototypes built, but I got distracted by my day job, and didn't get round to releasing it. If anyone is interested, then get in touch and I'll move it forward.

After the first installation of the Hyperstar and it’s collimating do you have to collimate the Hyperstar or secondary mirror every time you switch back and forth?

So...... I travel with my EdgeHD8 for outreach, etc. Guessing Hyperstar would be a Bloody inconvenience, because right now the rig itself (known as Scopezilla) has guidecam, widefield ED72, 2 cameras and electronics all on a crossbar attached to the EdgeHD. But I guess when Hyperstar is installed, No dust cap can be added, and Hyperstar needs to be Removed each time...Because I guess the last thing you want to do also is travel with it installed and increasing stress on the Corrector plate, or simply more chance to knock it and just break the plate anyway... So - looks the the Hyperstar will have to wait until the Observatory is built...But then something to look forward to making the EdgeHD8 usable far more than it currently is.

@johnnydanger8701 Месяц назад

If you have a dew shield on it, which one should, especially an aluminum dew shield then you don’t need to worry about it. You can also put the cap on the end of the dew shield.

@lklmmedia4715 Месяц назад

@johnnydanger8701 understood...except, i'm talking more for constant travel to darksky sites and Outreach, dew heater band is permanently around the scope, then dew hood is basically just material which can be folded down for travel, thin carpet from bunnings actually (more like black Speaker material), because it adheres to velcro, which is around the outer of the OTA, very easy to On and off the Dew shield, then when that is taken off to travel again, the cap goes on the OTA as designed. Suppose more than anything asking/wondering whether Hyperstar OR RASA are worth the trouble for NON observatory permanent installations.

@johnnydanger8701 Месяц назад

@@lklmmedia4715 I wouldn’t use either for outreach because they’re not able to do visual. I wouldn’t want to be fumbling around for 30 minutes adding or removing the hyperstar and AP gear to add EPs to the back of the SCT. I suppose if you wanted to have it set up to show people pictures on a tablet with live stacking or something similar then it would be helpful since it’s going to acquire the data much faster. You could set it up and have people watch the image essentially develop over an hr. As for being worth it in non permanent locations, Yes. It doesn’t take me any longer to reconfigure than it does for planetary. Celestron now makes an aluminum dew shield specifically designed for their Edge SCTs that has a locking end cap. They also sell dew rings that replace the ring for the corrector plate. You could safely leave a hyperstar on indefinitely and transport. The corrector glass takes a significant amount of weight to break. As for the RASA it would be the same situation, except if you didn’t have a dew sheild you could just remove the camera and adapter/filter drawer and put the cap on. The RASA is less portable due to increased size. An Edge 11 is going to take a decent amount of muscle to transport and a RASA 11 will take more. That said, people transport Edge14s.

@viniguez487 Месяц назад

Easy. RASA. Who wants to waste time setting up and calibrating every time and losing precious imaging time. Better to have two standalone scopes for separate purposes. I have both RASA 11 and Carbon Fiber C11. At a certain point it's worth spending more money to save time especially as we get older.

Damn I'm not a real astronomer I feel so ashamed 🤣On a serious note I notice you use a V1 RASA like what I have but autofocus has always been a pain & I never managed to get mine to work properly so ended up going old school using a mask which isn't great, I don't know if it's the mirror flop that's doing it. On another note why do Celestron sell them with garbage camera adapters so when you use an APSC sized sensor the vignetting is horrendous for what these things cost new you'd think they'd have M54 adapters. But I will say when they work & all the niggles are ironed out for what it can get in such a small amount of integration time is phenomenal if you can forgive the headaches it can pose.

@DylanODonnell Месяц назад

Yeh I'd like to see them iterate the range ... the more modern RASA 8 was better than the 11 for those reasons and I'm sure they could tweak it here and there.

@johnnydanger8701 Месяц назад

I’d think the main issue with Hyperstar and RASA auto-imaging would be autofocus throughout each night. If you can do that without having a huge obstruction then everything else is easily mitigated. Diffraction spikes - 3d print cable curve that completely eliminates them. Filter swap - Use SGP or NINA to auto-image multiple targets on night one with R, then same on N2 with G, N3 w B etc. The only situation it wouldn’t work for IMO is if it’s remote and you didn’t want to use an OSC.

@@user-ku4yk4ut4z I blanked out on the rear focusing with the RASA. I was thinking that if the mirror isn’t locked down then it might cause problems. Ideal focusing with an Edge is having the mirror locks engaged and an auto focuser such as a Moonlite NightCrawler or PrimaLuceLab Esato.

@adenwellsmith6908 Месяц назад

I've been watching some videos on NINA. I can't help but think they have got it wrong on the scheduling. This comment was triggered by your changing filters bit. Most people have a a list of targets they want to get. So setting up a job for each make sense. What I think NINA should then do is have means of setting a score on each job. The highest scoring job gets done first. The score relates to things like how high the target is above the horizon. Where the moon is, and what the equipment sent up is there. So if you have a red filter in, its going to pick off the highest priority tasks that need a red filter. NINA also needs the two telescopes one mount sorted.

@DylanODonnell Месяц назад

True. The one thing that bugs me about NINA is the wasted time in session recovery, if it recovers at all. One errant cloud and it wastes 30 mins and dud subs before realising something is wrong. It should halt guiding if the guide star is lost for too long, stop exposing, wait, plate solve, and try again all in a minute after a cloud. I could be doing something better I'm sure, but NINA too probably.

@adenwellsmith6908 Месяц назад

@@DylanODonnell Half reverse engineering it, there is an issue that the type [Telescope] and an instance of that type are confused. Another example, wait for 5 seconds. The system should know, when was the last time I moved. If its a wait for 5 seconds, and its been stationary for longer, don't wait. One other design issue. Local or remote? You should be able to run remotely on say an computer on the telescope, and also have an instance elsewhere the just says, I've a camera but its running on a remote instance. If that is done right, then you can get things like collaborative projects where people pick off a task to perform from a central NINA instance, post back. It's all coordinated. The next bit, when I look at post processing. Well doesn't that look like a NINA scheduling job?

@@DylanODonnell I find that oversight in the program is somewhat disappointing Dylan as all I hear is that this software is better than anything else around. I do have NINA installed on my mini pc but have never used it in anger as SharpCap v4 does everything I currently need and is very easy to use. The guiding does of course utilise PHD2 but if the guide star is lost, SC pauses the capture and discards the sub, waits for a while then tries to restart the guiding, if that is successful it restarts the imaging routine. I'm not sure if it can perform a plate solving routine, though the programming is very flexible and plate solving is used for target acquisition. Anyway, I've been using this for around twelve months and it seems to work fine. Even on nights where there have been fairly frequent cloud induced guiding failures, the target appeared to have remained pretty well centred. To be fair my set up is relatively simple so it doesn't require a more sophisticated program to run it. The only problem I have with Sharp Cap is the latest version (v4.1) won't run properly on my Eagle LE Windows 10 mini pc.
