From 5:39 p.m. tonight – another faint ISS pass – this time due to a blazing Moon directly behind me. You can JUST see the ISS running across the middle of the image.
Tonight’s ISS pass in nautical twilight (too light really to take the image) – but you can just about make it out.
This is an image of the Triangulum Galaxy – Messier 33 – and it has been a little while in the making. This image is a composite of data taken with the Sky90 refractor and M26C OSC CCD, the Hyperstar … Continue reading
It’s been a loooong time for one of these – so I’ve got a bit out of practice. But this was tonight’s Space Station pass at 5:37 p.m. I got part of a nice long 6-minute pass and you see … Continue reading
Insects can inspire those researching into advanced optical devices. This is a Morpho Rhetenor butterfly – and that intense blue metallic-looking colour is due to the structure of the butterfly’s wing scales. Each scale acts like a tiny photonic crystal … Continue reading
Star reduction does a nice job on the California nebula – image taken using 3 x Sky90s and 3 x M26C OSC CCDs (non-Trius). About 16-hours of 15-minute subs (I think without looking it up).
Managed to find a gap in the clouds last night to grab this image of Delphinus taken with the 200mm lenses and the 2600MC Pro CMOS OSC cameras. This was 28 x 10-minute subs and the last hour of data … Continue reading
This is a composite image of the IC410/IC405 region using Sky90 data (34 x 20-minutes) and 200mm lens data (76 x 15-minutes). A pretty mediocre looking image seeing as there’s 29-hours worth of data in there.
My free trial of Russ Croman’s StarXTerminator ran out, so I just bought the full licence. In celebration I ran it on an old Sky90/SX M26C image of IC410/IC405 which was 34 subs at 20-minutes per sub. In this version … Continue reading
