Hello, I am a young and new ametuer astronomer and I live in Singapore, a small island city. It is Bortle 8-9 here and the seeing is around 4-5/10 (sometimes 3) on the Pickering scale. Quite bad conditions. I heard that the seeing limits the useful aperture I can get for a telescope but then the bad light pollution makes me want to go a little bigger. Right now, I am considering an upgrade to a 127mm Skywatcher az5 Mak f/11.8 and the 130mm Skywatcher az5 Newtonian f/5 for visual, maybe a few snap photos using my phone. I currently own a Celestron astromaster 70az. I do not know if those two skywatchers above will give me much better views of the moon, planets, double stars, open star clusters than the Celestron astromaster 70az because of the seeing. But I also heard of something called a Mak to sct adapter and a focal reducer to make the Mak into a Low f/ratio scope to replace the Newtonian. I want those two scopes because the newtonian would be for dso while the mak is for high mag of moon and planets and double stars. So I have a question: Should I get the Mak and Newtonian ota with one quality altaz mount or should I just consider the Mak with the mount and get a sct adapter and a focal reducer. I do not know if the Mak to sct adapter and visual back would be needed for the skywatcher az5 skymax 127 or i only need a focal reducer to lower the f/ratio without a adapter and a visual back, i hope someone who owns the az5 package can help clarify,Thanks! -Entrpy53
