Not sure if I posted this one years ago - but I just came across it again. A 9-microsecond freeze of an air rifle pellet taking out 2 eggs. The air rifle pellet can be seen off to the far left. And the eggs were later eaten by the dog - so no waste. Greg

For a number of reasons I've decided to quit Facebook - so it's either here or www.newforestobservatory.com for my latest piccies Greg

I've seen nothing but good reports on the 10 micron. Greg

Nice job Ray Greg

This was an interesting exercise that I almost got right. A long 6-minute pass of the ISS last night, so long that it went out of the field of view of the fisheye lens. So I rotated the camera as the ISS went over the meridian and carried on imaging. Didn't realise that I had managed to get that tree in on the far left so I made the mistake of rotating the camera a 3rd time - and unfortunately the 3rd dataset wouldn't merge with the first two sets. So I don't get the ISS moving behind the tree Never mind, I'll know what to do next time. The ISS trail is in 5-second bits as it was still pretty light at 19:15 and this was at ISO 100 (my minimum).

This is a composite image of Coddington's nebula together with Carbon star SAO 15274 (bottom left hand corner) taken with the Sky 90 array. 5 hours last night and around 12 hours over 2 nights some time ago. Greg

I recently took an image of Greg's "3" asterism in Leo on the 200mm lenses. In this image I have inserted old Sky 90 data. Greg

Cheers Shane - sounds great from the cooling alone!! Greg

Which camera Shane?? Greg

Yes on cold nights -25C is no problem - but during the summer -15C is the best I can do. Greg

Combining with the other data reduced a lot of the muck, but also I took a load off the left hand side in the first one that I didn't have to do in the second one Greg

Here's the reprocessed image using up to date calibration files. The two bright red stars over to the left are both Carbon Stars. Greg

Just realised that last night's data was actually buggered because the calibration files weren't right for one of the cameras. End of last year one of the cameras went back for repair - I didn't redo the BIAS and FLAT frames, and a close look at last night's image shows artefacts. So right now I'm making up new sets of BIAS and FLAT frames for both cameras, and then I'll redo the last 3 sets of data. Greg

I got 18 x 15-minute subs with the 200mm lenses on this region last night and combined it with some earlier 200mm data. Greg
