Description

This is a 0.5x crop of the full frame. The imaging scope is F10 operating at F5 with an Celestron reducer with spacing = 180 mm.

It is taken with the good old Meade 10" LX200 classic system with an upgraded LX200Astar panel which gives better tracking. The autoguider tracking correction rate is 200 ms. A piggyback 80mm guiding scope is used. The primary mirror is locked by use of homemade MAPUG design locking screw with spring.

I think the nice round stars shows how good this system really is.

Total exposure time is approx 4 hours with 5 min LRGB subs.
