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 →

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.

These images of the Caph & Ruchbah regions of Cassiopeia are 2-frame mosaic taken using the Canon 200mm prime lenses and the Trius M26C OSC CCDs. Each frame of the Caph image was 2-hours of 10-minute subs, and each frame … Continue reading →

A 2-frame mosaic using the Canon 200mm prime lenses and the Trius M26C OSC CCDs. This is Castor (upper right blue star) and Pollux (lower left yellow star) in a Gemini star field. Castor frame was 20-subs at 10-minutes per … Continue reading →

I think this is probably my favourite image taken with the 200mm lenses and Trius M26C OSC CCDs so far. This is a 2-frame mosaic of M44 (the Beehive cluster in the centre) “Stargated” by the 4 central stars of … Continue reading →
