Images taken with the Hyperstar and SXV-H9C Camera
Jan 22 2012
Here is a 4-frame mosaic of the Pleiades taken with the original Hyperstar lens assembly (on a C11) with a tiny little H9C one-shot colour camera. Also happens to be one of my all-time favourite images.

Here is a wide-field composite image of M78 and its relation to Barnard’s Loop taken using both Sky90 and Hyperstar I data.

Another deep-sky image from the NFO archives, and another original Hyperstar/H9C composition. This time the Cave nebula in Cepheus. I recall the tracking was so good on this one that I actually got some vertical banding where the tracking error was well within 1-pixel for the whole imaging session. Not sure why it was quite so good that time, something to do with where I was imaging in the sky as well as several other things all working together with me for a change, but I never managed to repeat the precision tracking with this system afterwards 🙁
Another old image from the New Forest Observatory taken with the original Hyperstar and a little SXV H9C one-shot colour camera (1.4 megapixels only!). The camera was highly sensitive and I regret selling it when I bought the APS-sized chip M25C. This image of M78 was taken using just two hours of total imaging time showing the enormous speed (f#1.85) of the original Hyperstar.
Another image using the original Hyperstar and the little H9C one-shot colour camera. Pretty deep for just 2.5 hours total exposure time – shows the speed of the Hyperstar lens 🙂
I just came across a load of very old imaging files taken using the original Hyperstar (no collimation screws) and a tiny little H9C one-shot colour CCD (1.4 Megapixels from memory). Did a pretty good job all told, and this image was a huge pile (probably in excess of 100) short exposure subs (a minute or less per sub). I wanted to catch the “thuderstorm region” between M43 and NGC1977. I will post up more memory joggers as and when I find them.
I came across this print of M42 while looking through some old notes. Print you note – not data – the data has long gone. So why a print? Because when this first came out of the Hyperstar I and SXV-H9C camera I was completely gobsmacked! A thirty second sub (I knew nothing about multiple subs and stacking when I started) with the faithful old C11 in Alt-Az configuration. I thought this was the bees-knees. In fact I was so pleased with it I printed it out and gave it as Christmas Cards to the neighbours in 2004.
O.K. so I’ve learned a little since then – but I can still remember the feeling of elation with those very first images I got at the New Forest Observatory 🙂

Here is the second marathon processing session by Noel. This time it’s the Belt region of Orion. Read the rest of this entry »Tags: Hyperstar, Sky 90, SXV-H9C, SXVF-M25C

Taken over several years this image is a composite of Hyperstar I, Sky 90 and Hyperstar III data. Read the rest of this entry »Tags: Hyperstar, Sky 90, SXV-H9C, SXVF-M25C
