10 UPGRADES for a Newtonian Telescope

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.

Here is the secondary mirror holder and primary mirror mask from Backyard Universe:

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.

This was an excellent video with high production value.

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!

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.

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

Awesome Rob

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.

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

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!

8" all the way! Aperture is king!

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

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.

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

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 4 ай бұрын

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 4 ай бұрын

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!
