30cm Newton, QHY268M Pro, B,V,R,C filters

On fork mount. Mainly for photometry observations and also for some astrophotography. OnStep controlled mount (Fysetc S6 + TMC5160) using Kstars & INDI.

We masked primary mirror and replaced low cost second mirror holder used by manufacturer. final image seems to be vegry good and whole setup is performing well. also 16bit CMOS camera QHY268M is superb performer.

custom secondary mirror holder for stable colimation and to reduce difraction spikes Original image

Telescope and roll-off observatory was finished 17 November 2025. First light report is here.

We spent two or three weeks during summer and autumn of 2025 to build new home for telescope. It was hardcore astropunk project with more then 12 people involved. Kaja Sobotka and Milan Udatny above all. Thank you guys. All of you. New toy available at request to anyone who helped!
