Daystar Quark Chromo VS Daystar Combo Quark for my f9 refractors?

Post by fedele »

hi
i have two refractors:
FC100DL
SW120ED PRO

and i m planning to buy the TS INDIVIDUAL 152/900 Acro FraK.

1) Is best to have a Daystar combo and a set of Telecentric Barlow or the Quark? i see this is a more polifuntional setup. Is correct?

2) Now i have only one telecentric Powermate 2,5 x

thanks

Standard Quark has a very adequate telecentric system with 4.2x amplification. This makes it suitable on most refractors - F/10 and faster. Combo is for very slow telescopes like F/13 and slower.
The native 4.2x telecentric was specially designed for Quark with it's small 20-21mm size etalon. This telecentric is cheap in the manufacturing and so, it offers the most economical way in an entry level H-a imaging/observing.

Saved money (vs Quark Combo + several telecentrics) better to invest in a good full size DERF for your coming 150mm refractor.
