Re: LT 的 DIY 及 modified 天文器材配件相片集 -- Cage for VMC110L

26. Cage for VMC110L

Going to modify Vixen VMC110L scope. Firstly make a cage to replace the left one (original cage) so that the optical axis of the secondary mirror and
meniscus lens assembly can be adjustable.

Re: DSO 遺照集 -- M42 (reprocessed)

Reprocessed again with not so aggressive curve stretching, and seems this one looks not so grainy than the previous one.

24. Spider of my DIY 6" F4 Newtonian

Very unfortunately, this spider failed to hold the secondary mirror firmly, and so it needs to be replaced by another much more stronger.
