Hello Luke, I hope that you're doing well. Thank you so much for this interesting video. I really enjoyed it. Please, can you make a video showing how fo do it with only free softwares like SIRIL and Photoshop? As well as how to make SHO rainbow colorized edits from HOO image (no SII, for those having only a Narrowband filter ) That would be extremely appreciated, I've been searching for this kind of tutorial for months, untill I fell on you viddo, but unfortunately I don't have Pixinsight. Thank you so much in advance. Best regards
As someone who has been using fast Newtonians , there is always a cost, that may not compensate for the speed they have. People overlook this easily. In astrophotography there is always a con for everything! That cost is that around F2-F4 is, that every tiny issue someone may have, like a small sensor tilt or a small backfocus issue will be severely enlarged. Add or remove 0.05mm backfocus and your stars are out of shape. This didn't matter on your F6 refractor, but it matters hugely with the F3 scope. Change in temperature and the focus point changes by wider margin. Having a tiny sensor tilt that didn't matter on an F6 scope is now a much bigger issue with the F3. A slight focuser sag or moving focus will ruin all the shots. At higher speed, everything little problem is also 5-6X magnified compared to a scope with half the speed. I won't even mention filter compatibility, because there is a reason that for example Baader makes "fast optics" narrowband filters and they cost somewhat more than just the regular one, but even if they weren't, now you gotta buy a set of filters only to be use with a certain type of telescope. There are just filters, that may work on 98% of all the telescopes, but NOT on your F3 or F4 telescope. Totally possible! I'm just saying- fast scopes are fun and work well, but be prepared with all the cons attached to them. You might not only be using a different scope out of many, but you might have to compensate to it with the entire gear and they require far more precision (backfocus, tilt etc) and yet you might still not going to like what you get, despite the extra photons advantage, especially if someone has been using a well corrected, optically excellent - but slower refractor.
I've been asking questions about the 3 amp spec for the AM5N on the ZWO Facebook page and received this comment "ZWO Astrophotography AuthorAdmin The DC port on the saddle can support a maximum current of 5A when used as an output port." Based upon my current demand measurements, this means I CAN power everything, including the ASIAIR, dew heaters, and my ASI2600MC Pro from that DC output, leaving no wires hanging down from the saddle.
Thanks for a concise explanation. It helped me to refine my use of the GHS process and made it much easier to understand and use. Keep up the great work!
One tip about BlurXT - if you run it twice - once with the 'correct only' box ticked, that'll get rid of the chromatic abberation and misshapen stars. Then untick that box and run it a second time like you normally would. Then your stars will be much cleaner.
A lower Fstop collects light faster if that is considered Important in this demonstration. Also it might be important when figuring out a camera to match your ota for "proper" sampling.
Sorry I missed your live stream … was imaging the Eagle Nebula last night. I noticed you are using several different binning setups. What do you use that for?
Watched this early on this morn, Just had to catch up... some top support from your viewers.. Pete is a gem (one of the kindest guys ive seen) and all the others that showed there support was awesome.. Clear skies guys..
I am really enjoying your content Luke, as an old guy but a newbie in the hobby I always gain knowledge from watching your tests. I tend to stick with shorter subs as it's less painful to throw out a short sub due to a plane or satellite and clouds that come into view during exposure. I would really be interested in the narrow band duo filter test as I'm using a OSC camera and have only recently picked up some Askar C1 and C2 filters for my own testing. I'm still so new that most of what I'm doing is live stacking on the fly but saving the images for later processing. It's baby steps for me so that my brain can retain what I'm learning. Thanks Luke and all the best from SE Utah, Cheers !
Congratulations Luke🎉 Few things in life are as meaningful, rewarding and frustrating as becoming a parent. I have 3 boys myself, 11, 4 and 1 and each has been a unique experience!. Best advise I can give you is to go into this as a team and hold onto the belief that you’ve got this (or will get it eventually :) In the end the baby just needs your love and attention, and you’ll get tenfold back
The one on the right definitely seems to have more detail and contrast ... at least to me. Maybe not when zoomed in on the tiny galaxy, but for sure when zoomed out all the way.
Hey mate, You are a right legend! Thank you for sharing your tips and experiences here at RU-vid-You sure are gifted at this universal hobbie we all share a strong affection for. Your talent and dedication is most appreciated and your presentations are extraordinary. May you continue such exceptional work well into the future buddy. Sending you many blessings and light from Australia!
Luke, you sure have a fine eye for detail. My AM5 has been amazing and at this point I doubt my wife could possibly understand why I’d be attracted to the new upgrade. Fortunately, after watching your video explaining that the differences are relatively negligibly minor, I’m going to relax a bit and continue to enjoy my “old” AM5 (while keeping harmony in my marriage 😂. PLEASE, please do consider making a video on how to adjust the AM4 to be used for visual astronomy, I haven’t found any videos that encourage me to take that leap. As always, brilliant insightful analysis.
Hey Joe!! I think you're spot on mate, no major need to change out your perfectly good AM5! Re: visual setup, that's a good idea, I'll have to do that! :-) Clear skies mate!
Hey mate - Nice overview pal. I wouldn't mine one of these if I did a bit more travel with my gear, but Im toooo lazy 😂 the Heq5Pro is pretty solid for now.
Great video as always! Going to try it on my first narrowband capture ever of the Eagle nebula! I was doing some testing and didn’t expect to be able to capture any data just seeing if I could get focus and stuff like that. I didn’t even polar align. Somehow my guiding was 0.7 arcsec so I just picked a target from the sky atlas in NINA and left it overnight. Using L-ultimate and 4 min subs I got 3 hours of data. I was shocked to see the images! Never seen that many stars before since I was doing broadband from Bortle 8/9 skies.
Great video but I believe your trial parameters are misleading. In the terrestrial trial, you use an identical focal length whereas in your astro-trial you compare the RASA11 with a FL of 620mm with the Askar120 with a FL of 840mm. The difference comes into play when you look at the light you received from the same object In addition, the RASA has a central obstruction that takes away 16% of your light compared to the Askar. Both parameters downplay the difference in focal ratio.
Great experiment. I believe that AI, high resolution cameras and tools like PixInsight have changed astrophotography. Luke what do you think is the ideal refractor size for planetary imaging? I've been thinking a 150mm Sky Watcher on a EQ6R Pro mount
Hey Craig! Glad you enjoyed it mate 👍 Re: refractor for planetary, as big as possible (while maintaining quality) is the best option! :-) The Askar 185 apo would be ideal but it's quite expensive, the SW esprit 150 would also be good, but the evostar 150ed may suffer from some false colour fringing on bright stuff like planets/moon limb 👍 Hope that helps!
ZWO really listens to their customers and I can see nice improvements here. Curious is the new case allows the mount to be placed back inside without having to adjust the altitude (latitude). The soft case is great that way. Unlike my HEQ5 styrofoam boxes, the old AM5 case allows replacing the mount without adjustment. I do note the new color is more red and a bit less orange.
Hey there my friend!! I'm very impressed so far, I must say! :-) Re: the case, you do indeed have some wiggle room for the altitude being left adjusted when put away 👍 Cheers!
