Microtech 8" in Newtonian Reflector ( ? )   

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!

Dwarf II Smart Telescope (2023) 













Appolo - MC 120D 

Aperture: 102mm,  Focal length: 1000mm,  F/10,  weight: about ?? Kg

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!
