The day after I took the Altair left hand frame it was clear again – but with a lot of thin high cloud. Never mind I’ll still image just to keep the kit running over. Decided I would go for … Continue reading

This is a 2-frame mosaic of the whole of Canis Minor taken with the Canon 200mm prime lenses and the Trius M26C OSC CCDs. Bottom left is Procyon, top right is Gomeissa. Now I have no idea how this happened … Continue reading
A zoomed-out image of M31 taken on the Canon 200mm prime lenses and ASI 2600MC Pro CMOS cameras together with a zoomed-in image taken with the Hyperstar 4 on a C11 again with an ASI 2600 MC Pro CMOS camera.
How many galaxies here? This is a 2-frame mosaic of the whole Virgo/Coma galaxy cluster region taken using the Canon 200mm prime lenses and the Trius M26C OSC CCDs. Each frame is approximately 4-hours of 15-minute subs
The central bright star is Sulafat – move to the right hand edge at the 2 o’clock position from Sulufat and that is Sheliak – these are the two bottom stars in central Lyra. Move 3/4 of the way from … Continue reading
Here is another 2-frame mosaic from the Canon 200mm prime lenses and the Trius M26C OSC CCDs. It is centred on the Crescent nebula in Cygnus. And it needs more data!
I found some more old 200mm data of this region from 2015-08-08 which had 8 x 30-minute subs. I added this to the previous 10.42-hour
Yet another 200mm lens and Trius M26C OSC CCD 2-framer. This time it’s the Aldebaran region including part of the Hyades and open cluster NGC1647 (top left). Only 2-hours (total) of 5-minute subs.
