SkyWatcher 120ED PRO (since 2011 Nov)
with Vixen GP equatorial mount
SkyWatcher 120ED PRO + Vixen GP 赤道儀
Aperture: 120mm, Focal length: 900mm, F/7.5, weight: 4.4 Kg
這支折射鏡相當好，我很喜歡。

EQ6 Equatorial Mount
Celestron C8 (since 2000 Feb )
with Meade LXD75 equatorial mount
Aperture: 8" (inch), Focal length: 2032mm, F/10, weight: about 13 lb ( 5.9 Kg)
太陽光學買的，買來光軸就不準。
Aperture: 8" 200mm, Focal length: 800mm, F/4, weight: about ?? Kg
上宸買的周年慶特價品，
光學品質相當好，1/10 波長精度。
可惜很重，
可惜直焦，直接接單眼相機 時無法合焦！
Meade LXD75 equatorial mount
I do not think this is a good equatorial mount, because (1) The RA motor burned out twice. (2) There is a gap about 2 degrees when crossing meridian. Presently, it is not working.
Vixen GP-80M.SM ( since 1994 Dec ) with GP equatorial mount
Aperture: 80mm, Focal length: 910mm, F/11.4, weight: about ?? Kg
早期吳志剛先生推薦給我的「入門鏡」，品質非常好，我非常滿意！
這支折射鏡看天狼星，可以看到繞射光圈，已經到達光學極限，
所以我認為品質非常好！

這組號稱地面與天文觀測都很好，實測是光學品質很普通，
地面與天文觀測都不很好！
