Planets

I'd say more aperture isn't always the best thing to go for, because bigger telescopes require more cooling to give best views of planets. For this reason, I'd not usually recommend big catadioptrics due to their closed design, requiring long cooldown times. Newtonian's open design and less central obstruction is better in this regard, but still, 250mm or even 200mm isn't something you can just bring out and expect optical views. Also, bigger telescopes are more adversely affected by poor seeing. Yes, go for the 250p Synscan. For Imaging, you can't beat aperture, as software nowadays usually take care of poor seeing. But spend the rest on a good quality, long focal length 102mm ED refractor, or even 120mm if money allows (or you can downsize to 200p Synscan to allocate more to refractor). It will allow for planetary viewing with minimal cooldown when you don't have much time. You'd need to consider mount as well, but 102mm could go on same mount as C6.

Looks great, however, I've seen reports online that F15 127mm Maksutovs suffer from mirror flop unlike Synta F12, does it occur in your unit too?

Is there a mount similar to the Skywatcher SupaTrak alt-az mount but sturdier? Those not familiar with the discontinued SupaTrak mount, it resembles Skywatcher and Celestron basic alt-az goto mounts, such as SLT, AZ-Go2, Astro-Fi etc but unlike those it only tracks and doesn't goto objects. I really like the SupaTrak's simplicity, because there's no need to enter coordinates, time, star alignment, wi-fi etc. Just set your latitude which the mount remembers and there's useful latitude markings on the mount already for that, then point to the North while the telescope is fully horizontal and you're done! I understand that equatorial mounts do exactly what I'm looking for but I'm put off because they don't move up-down left-right like SupaTrak or any alt-az mount. So far I've been unable to find a sturdier alternative. Someone knows any?

How does the Bresser F/15 127mm (not F/12 Skymax) compare against C6 SCT? Has anyone compared these?
