“The Propeller” in M13

I have very deep data of M13 and for the first time today I took a good look at the image to see if I could find “The Propeller”. And there it was!!

Two Carbon stars near Cygni 32

Last night I managed to get 10 x 10-minute subs using the Sky 90 array on the Cygni 32 region.  Pretty amazed that I could see some nebulosity with so few (shallow) subs.  Anyway – main point of the exercise … Continue reading

The Virgo/Coma galaxy supercluster

12 frames using the Hyperstar III and M25C camera with 2-hours of 10-minute subs per frame.  Also a 200mm lens with M26C camera 2-framer using 15-minute subs and 5 hours per frame.  So total integration time is 34 hours 🙂

Pac Man nebula reloaded

I composited some 4-hours of Hyperstar III data and some 6-hours of Sky 90 data to give the following deep image of NGC281 – the Pac Man nebula.

NGC1333 reloaded

I was looking through some old data yesterday and NGC1333 (Hyperstar III data) stood out as worth taking a second look at. So I reprocessed the data and came up with the (slight improvement) below 🙂

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 California nebula – work in progress

On the evening of the 19th October I got a couple of clear hours before it clouded over.  Enough time to set up the Hyperstar and get an hour (4 x 15-minute subs) on the California nebula.  I had forgotten … Continue reading

Collimating the Hyperstar III

It is possible to get perfect stars right across the diagonal of an APS-size chip such as the Starlight Xpress M25C or M26C – but only if your Hyperstar imaging system is in very good collimation.  Getting good collimation is … Continue reading

The Hyperstar III is back on-line

I have completed the initial experiments with the Canon 200mm lens piggy-backed on the C11, so yesterday I removed the kludge on the back of the C11 and re-instated the Hyperstar III – just in time for all the winter … Continue reading

Better luck second time around

Managed to get 15 x 4-minute subs using the Hyperstar III on the new supernova in M82 last night.  Although the sky looked crystal clear, and was Moonless as a bonus, the seeing was terrible.  Never mind – I do … Continue reading
