Description

Ok, got my old Newtonian modified, edition 2020 you may say. And the "Cave Nebula" is a lovely object - mix of 3 different types of nebulae - emission, reflection and dark nebula.

The following modifications have been made:

+) new velor covering the inside of the tube

+) main mirror got an aperture ring on the outside to improve the star spikes

+) second mirror got new (black) colour to suppress reflections

+) new, improved focuser with steel inlays

+) the "spider" holding the secondary mirror is now in a matte finish

Description: Glad I could add data from a second night and therefore double the total exposure time.
