M31 in Perspective

Managed to get out imaging with the 200mm lenses until 1 a.m. even with an intrusive Moon. Decided I would go for M31 to get the whole thing in the frame. Managed 4-hours of 20-minute subs in the end and … Continue reading

M31 – The Full Monty

This is all the Sky90 data plus all the Hyperstar 4 data I have on M31 put together. It is a damn shame the outer edges of the galaxy are cropped – that’s why this is an on-going project 🙂

Hyperstar 4 Image of M31

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

The Whole of the Virgo/Coma Galaxy Supercluster

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

Sulafat & Sheliak

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

From the Butterfly, Through the Crescent, to the Tulip

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!

North America & Pelican Nebulae

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

The Cygnus Wall

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
