Re: Anyone has any experience or comment about meade starnavigator ng or polaris 130 telescope?

Just make sure to avoid the powerseeker127 because it is bird-jones lens inside. It's something bad. If you slowly hunt for a proper parabolic newtonian it is possible to still fit inside the same budget or price.

Re: Building a DIY F/15 Refractor

The aliexpress photo show glued objective , so perhaps expect slightly more edge abberations than air-spaced.

Re: 5" vs 6" SCT viewing/ astrophotography in Singapore

If you were comparing the nexstar SE series , then the 4-5 vs 6-8 have different mount although they look similar.
The jump from 5 to 6 is not just the telescope bigger but also the mount.

Re: Telescope for Astrophotography(?)

Those 2 telescope you quoted are maksutov design , unsuitable for DSO astrophotography.

Weak mount weak tripod (relatively cheaper) limit your upgrade options when your scope or instrument get heavier in the future , later you end up buying twice ...

Re: How much I can see with a 76mm (FL 700mm) reflector?

76mm F10 usually mounted on a yoke design tripod mounting , that's not good to use.

Entry level stuff top out at around 1x mag per mm , the 2x number quoted on website are for better polished optics. Celestron website goes even further quote around 2.3 to 2.5x per mm , misleading.

Re: WTS: Explore Scientific Twilight I with modifications

For my mount I filled the arm empty area with epoxy and drilled out the bottom 2 of the 6 holes at the side to attach 2 more bolt and nut. M5 size fit well.

Worth a try. Low cost materials, big improvement.
