I combined an earlier 2-frame mosaic of the Altair region with the recent single-framer, both taken using the 200mm lenses and ASI 2600MC Pro CMOS cameras, and this is the result. Probably no more to be done here.

Got 2/3rds of the way through setting up the 200mm lenses last night, and this is just 9 x 5-minute subs on cameras 3 & 4 on the Pleiades. For such a short exposure time I am pretty pleased with … Continue reading →

It was clear again last night, but as the Moon was beginning to get more intrusive I only intended to work on the collimation of camera5 (200mm lens). However, after getting the best collimation I could, it felt a shame … Continue reading →

Fired up the 2 x 200mm lenses and 2600MC Pro CMOS cameras last night. Started at astronomical darkness (now 10:00 p.m.!!!) and finished when the mount hit the Meridian and also cloud started rolling in from the West at 12:30 … Continue reading →
