Most guys will steer you towards a refractor ( ED80 ) for AP as they are the most common scope used for AP but I decided to stick with newts
My 6” f6 is a tremendous scope for AP , my images are proof of the pudding. I had a Crayford dual focuser fitted in lieu of the single speed , dual is a must for AP
A word of advice if go down the newt path ( don’t go for a F4 Astro graph to start off with ) An F4 newt is difficult to collimate and doesn’t give you much tolerance. Go for f5 or f6 focal ratio
My 8” f5 I use at my dark site is unbelievable ( see my M8 lagoon nebula attached )
Anyway you have to get more advice off others , but I can vouch for my 6” f6 newt and my 8” f5 newt
Rule of thumb with AP is that your mounts final payload should not exceed 60% of its max rated payload capacity ( including telescope, all cameras , dew control , guide scope , adapters, cables and other accessories)
Cheers
