A very quick tutorial for collimating the Sky90
I just received a mail asking how you collimate the Sky 90. I do not have a Sky90 in front of me, so some of this will be down to my failing memory. From memory I think there are 3 … Continue reading
Just a reminder
Here’s a reminder that I used to take deep-sky images at the New Forest Observatory. This is a single-framer of the Sadr region in Cygnus taken with the 2 x Canon 200mm prime lenses and the 2 x Trius M26C … Continue reading

The NGC6914 region in Cygnus
Last night I got 7 hours of 20-minute subs on the NGC6914 region using the Sky 90 array. The result is shown here. As it is clear (and now Moonless) I am going for a bunch more 20-minute subs tonight … Continue reading
Another adopter of the light box for flats
Peter Rusling has also used one of the Amazon supplied light panels for taking flats. He says: “I’ve bought one of these excellent panels and thought I’d share that the light USB L4S version will mount safely on a £15 … Continue reading
You too can make your own high resolution deep-space images – without a telescope!
You too can make your own full-colour, high-resolution, deep-space images, just like the Tulip nebula mega-mosaic below – and you don’t even need to own a telescope. However, you do need a copy of Photoshop and a copy of Noel … Continue reading
Tulip nebula in Cygnus – The Full Monty
I have been putting together a full-colour mega-mosaic of the Tulip nebula region in Cygnus using the wonderful DSS2 data. As this is a pretty huge mosaic you can imagine the dataset was getting a bit unwieldy – and in … Continue reading

CCDInspector results of Hyperstar III collimation
A few posts below I gave a procedure on collimating your imaging camera to a Hyperstar III. On reflection I thought that this could be considered as so much “hot air” without results to prove the procedure actually works. So … Continue reading
The Double Cluster and Stock 2
I am in the final stages of setting up a new imaging system based on a Canon 200mm prime lens with M25C OSC imager and a 52 mm IDAS filter on the front of the lens giving me f#3.85 and … Continue reading
