Another (faint) ISS Pass

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.

4:50 p.m. ISS Pass

Tonight’s ISS pass in nautical twilight (too light really to take the image) – but you can just about make it out.

6-Minute Space Station Pass 02/12/2o22

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

Structural Colour in the Living World

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 Reduced California Nebula

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).

Composite IC410/IC405 using Sky90 and 200mm lens data

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.
