I found some Hyperstar 4/M31 data from 2021-10-11 comprising 33 x 3-minute subs – so I added this to the 52 x 3-minute subs taken on 22-08-25 to get the result above. So now a total of 85 x 3-minute … Continue reading
I made a composite image out of 2 lots of data of the Markarian Chain region taken using the Hyperstar 4 on a C11 with an ASI 2600MC Pro CMOS camera. This composite gives a total imaging time of 4.7 … 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
I dug out some very old (but very nice) data from a LONG time ago. This is an image of the Cygnus Wall taken with the original Hyperstar (no collimation or camera rotation adjusters) and a tiny little H9C OSC … Continue reading
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
