Depending on what FOV and detail you wish to achieve , a budget cost newtonian reflector with 6” and 8” aperture will give you satisfactory image results under varying Sky conditions at a low cost outlay

A basic newtonian reflector will definitely provide the biggest “bang for your buck” out of all the scopes and probably the most versatile all round type of scope as well

It’s not necessarily the scope that’s prime importance for imaging but the mount and camera would be top of the list for importance in DSO Astrophotography

Newtonian reflectors are simple in design and construction and require minimal maintenance if cared for. I check collimation before each imaging session which rarely changes unless I bump the scope. My mirrors are cleaned every 6 months depending on conditions.I use a Baader coma corrector to ensure my star field is free of coma across the field , it works extremely well on both scopes.

I have no experience with imaging refractors other than using them for my finder-scope and guide scope on the newt

Check out some of my images in the beginners Astrophotography section

I hope others will provide you some information on other types of scopes to give you and informative decision

Good luck

Just few points to tell you or let you know:

1. I have two mono cooled cameras, the same specifications just brand name different.

2. I have 6" F/4 Newtonian bought it this year, i already have 8" F/5 Newtonian i bought it back in 2018, both are nice although i tested them like twice, maybe 8" F5 4 times i think, but i stopped as i try to modify them first and i had other things to finish first.

3. I want very very much to use two scopes with my two mono cameras, i asked around and many told me it is very difficult or not working properly for dual imaging system, i really don't know why it can't be done, i saw few did image with dual system or even three.

4. I don't have big budget, and i really want to have another 6" F/4 to do dual imaging system, but i can't trust if my mount SW AZ-EQ6 will handle two 6" F/4 Newt with accessories including coma correctors and cameras and filter wheels, if it is possible then i just stop searching around and buy the second 6" F/4, otherwise i still keep searching for two small scopes to be mounted together to use them together at the same time, i hate using one scope and one camera only per night, i wasted so much time already.

5. I am trying to choose those two scopes to be good colors and in range of 250-500mm if possible, if i buy a refractor then all people said that only expensive triplet or even expensive doublet can provide better colors, that is against my condition for cheaper affordable two scopes, Newtonian is the best here for colors i saw, but the only problem i have is my possible limit capacity payload of my mount, should i risk it with second Newt or better keep searching, or if i have to wait longer to save then i waste and miss a lot of imaging targets and imaging seasons, i have to reach decision before November at least.
