You can't beat this doublet with anything from China. Forget Dawes limit; it does not apply as this scope easily exceeds 100X per inch aperture on nights of decent seeing.

Can be carried with all necessary accesories in a fat briefcase.

Takahashi Optics in a teenie package. The helical focuser is neat, but I replaced in with an Antares dual rate.

My problem with this scope is that the tube is too long (when used in conjunction with the Helical focuser) to reach focus using a 2" diagonal.

That said I use a nice 2 speed Crayford and 2" dielectric diagonal.

I use 80* Kohki Kokusai 30, 20, and 13 mm eyepieces and keep an original Nagler 4.8 around. I also carry an Antares 2" 1.6 ED barlow.

It does not eliminate all color on the brightest objects, but clearly - even above 250x the contrast and crispness is very impressive. That doesn't happen unless the luminance of the whole spectrum is very well constrained. At F/6.3 I don't know if a better doublet exists.

I use this strictly for visual grab and go, but plan to do imaging with it in the future. This little thin makes a 12 year old LX55 or LX75 Meade mount look like a champ; it is a "featherweight heavyweight".
