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).

The Whole of Delphinus

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

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.

Star reduced IC410/IC405

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

Star reduced Rosette nebula

This is only 10 x 3-minute subs on the Hyperstar 4 with the C11 and 2600MC Pro CMOS OSC camera – but application of the star reducer program really makes it pop.
