With planetary imaging a lot of things affect your outcome like image scale, focal ratio, atmospheric conditions and so on ..... that’s why they coined the phrase “Lucky Imaging”
My 8” f5 is a big an aperture as I will ever need , it can resolve most objects down to magnitude 10 on a good night.
A bigger scope would require an observatory as the scope then becomes a wind sock
I’ve never tried to collimate an f4 newt but many IIS members have said on many occasions stick to with an f5 as f4 can be troublesome
I enjoy visual astronomy so I only observe with my 12” Goto dob , it’s on an Az Alt drive turntable base.Its not designed for imaging and I never bought it for than purpose
Hope you gather enough information to make a decision on what scope you by. Remember that you can’t go wrong with a 6” or 8” newt ,they just simply work and work well , they are best all round scopes on the planet for the price
Good luck !!

The problem is, all people giving statement but what i see is completely different, and it is always as this "Believe what you see not what you hear or read", so about big aperture isn't always better, no that is wrong, it is always better, why, because in poor seeing all scopes are bad even 1 meter scope, even 1 inch scope, so i am an educated and i should never judge a scope under poor seeing, that is the worst conclusion, so when i always mention big aperture people keep seeing over and over again "POOR SEEING", oh yeah, but i don't imaging under poor seeing even if i have 10 meter scope, so what else you can tell me people?!!!
6" Newt i was looking for buying to do DSO actually, not planets, i can still use it for planets if i have to, but i already have 8" Newt and 7" Mak, for planetary it is very simple for me that i only go with 12" or larger scope, while for DSO, this is an open area, i can go with 6", 4", 10", 14", 2",...etc, for DSO anything is possible as i see people using all kind of scopes for that, from refractor to reflector to hybrid also, but i have to be so precise in my choices, 6" F4 giving a nice focal length that i can use for different targets and because of price i can even buy two of them, but does a 6" F4 Newt really is a good answer compared to for example 3"-5" refr? And if i will buy a Tak scope later in future then what will be the status of this 6" F4 Newt?
My mistake is i bought or have few things and stuff that making anything else or next step as difficult as it should be, i mean i don't regret this 7" Mak and many dream about it, but for me from 1 year only i already look for a bigger scope, there is one person i don't like in my country who bought C11 and C14 and he just put that C11 into sale immediately and producing amazing results with C14 and in less than 1 year he is already looking for larger scope, and he has 14", so, i think i am no different, i know that a larger scope is the only way in my life, it is just i have to make it large enough, not going with 11" now and 14" later and 18" after 3 years, but i know that being at 12" and larger is already enough for planets, i saw enough results from 12" that is not much apart from 14", and i still hold my plan on 20" Dob so i won't get 14" or 16" next to 20", but 12" can fit somewhere there fine, not 9.25", not 11", not 10".
