M31 – The Andromeda Galaxy Reprocessed
I used all the Sky90 data and added to it the core data I took on the original Hyperstar with the little H9C OSC CCD. There was a noticeable improvement.

Corona Borealis Reprocessed
I just reprocessed the Corona Borealis 3-framer taken with the 200mm lenses and 2600MC Pro CMOS cameras. This data was collected in June 2024 under astronomical twilight.
Picture of the Week

The 10-microsecond light pulse (150-Joules in energy) was taken using 3 Xenon flashguns developed … Continue reading

A beautiful, completely clear, Moonless night last night, and warm as well! I imaged from 10 p.m. until 1:15 a.m. with the 200mm lenses and 2600MC Pro Cmos cameras. Two targets: A star field in Ursa Major. Arcturus. The star … Continue reading
Picture of the Week
This week we feature a macrophoto of a Morpho Rhetenor butterfly. The irridescent blue colour is not due to pigment, but it is due to STRUCTURE. Acting like a diffraction grating (or a photonic crystal) it is the complex shape … Continue reading
