Here are my top 10 upgrades for a Newtonian telescope to improve it for astrophotography. These upgrades aren't specific to the SkyWatcher Quattro 150P; most will work on any Newtonian Reflector.

Hopefully, some of this will help you improve the images you get from your telescope the way they have for me.
Clear Skies!

@3:55 Lovely image first of all. and those funky spikes I also kind of like.

PRO TIP! After Primary collimation using main adjustment screws, finish up collimation iteratively with the lockdown screws till very snug to tight. Also for the primary, start with the main collimation screws fully clockwise and primary mirror bottomed out. Loosen one a full turn then use only two of the three screws to collimate. Do the secondary in the same manner/tightness and you shouldn't have to collimate hardly ever. Of course do the secondary first :P I have a 10 inch and collimation is solid for 6 months now and it's mounted/unmounted each night. Great video!

@Robservatory 5 месяцев назад

Great pro tips! I have been doing the same for a while and collimation seems to hold well. I will be doing a video solely about collimating soon and I’ll be sure to include your advice. Thanks!

@@Robservatory Cool! I rarely see mention of the rear fan and some actually block off the back altogether. In my experience I couldn't image without a baffled fan setup like you have. I tried using a lower CFM fan I had on hand, when my stock unit went out, but wound up getting all sorts of aberrations/ funky stars. The more air turbulence through the tube the sharper the image in my case. Huge difference. A filter on the fan help a ton too! Small scopes a clean beanie or something similar will help filter the dust! Have a great weekend.

This was an excellent video with high production value.

Nice video; thanks Rob! For my next scope, I'd like to go Newtonian but have never been around one. These are great pointers to help us understand what is involved when you end up with one. Now I just need to decide whether its a 6" or and 8" tube. Cheers man!

@Robservatory 5 месяцев назад

8" all the way! Aperture is king!

@stevenpeng5692 5 месяцев назад

Nice upgrade thoughts. But I would put a focuser upgrade as a higher priority on the list - the stock focuser sucks to say the least.

@Robservatory 5 месяцев назад

I haven’t had any issues with it, probably because of the EAF, which keeps it from slipping.

@Lyrenoorfeu Месяц назад

@@Robservatory I believe your split diffraction spikes are due to tilt from the Focuser not from the spider vanes, I have the same scope but the one with the “good Focuser” and the diffraction spikes are nice and straight. So I would recommend another Focuser instead of the expensive spider vanes.

@Robservatory Месяц назад

@Lyrenoorfeu The spider vanes fixed the issue, thankfully!

@AmatureAstronomer 5 месяцев назад

Good upgrades. Might work on my Celestron Omni 150 XLT Newtonian Reflector.

@Rtd_astro 4 месяца назад

Awesome Rob

@KiloFeenix 5 месяцев назад

I feel like a collimator should be number 1 on the list 😂

Thank you very much for this video.🔭

No worries!

2:59 in my experience it isnt constant unless you are using your newt as a battering ram or your fasteners have sloppy tokerances.

@misaelescobarruiz1193 Месяц назад

Muy bien amigo buenas tomas

@jamespeirce2582 3 месяца назад

Puzzled on the OAG recommendation. For a fast Newt guide stars should never be a problem on a relatively small-prism OAG? Due to the wider field of view and fast focal ratio.

@Lyrenoorfeu Месяц назад

That’s right at 600 mm focal length or even less if you’re using a reducer, I would not recommend an OAG.

@jamespeirce2582 Месяц назад

Not necessary. But there is also nothing wrong with using one that is how someone would prefer to arrange things.

@tostativerdk 5 месяцев назад

Thanks for a very useful video :) Must be awesome having an f3 scope! But I also noticed you use 3nm filter, don’t you get a lot of bandpass shift with that combo? Maybe partially offsetting the fast f ratio?

@Robservatory 5 месяцев назад

That is a good point. Antlia claims the filters work down to f3, and they do. They lose some transmission, but I can’t fire out how much. I’d like to upgrade to the high speed version and probably will at some point. I am trying my best not to spend more money at the moment!

@Robservatory 5 месяцев назад

Just a quick follow up. I just heard that the Antlia 3nm pro have been tested at 95% transmission for a parallel beam and 88% at f3.3. I would guess they are around 80% at f3, and with the mirror mask, I am probably at f3.1 or so. I can live with these numbers!

@tostativerdk 5 месяцев назад

@@Robservatorythanks for your reply, ah I see. Well then your combo makes a lot sense :)

@KaiHui-xm2mp 5 месяцев назад

Very informative!

@trevorworrall1226 18 дней назад

Are there issues with mounting the camera and filter wheel "vertically" on the OTA eg does the EAF struggle ?, I have a problem with 3rd axis ballencing and the amount of weight needed . I'm hoping to get all the gear on top similar to yours. ( great video BTW)

@Robservatory 13 дней назад

No problem at all. I use a strain wave mount, so balancing is not an issue. On a traditional mount it is best to have the camera facing down to achieve a lower centre of gravity and better balance.
