    From the album: Mars

    Night of the 9th October 2020. A clear night but unfortunately the Jet stream conspired to make images wobble like jelly on a plate! A stack of 9mins of RAW video clips. 127mm Meade Apo Refractor with 3x Barlow and QHY5-11 colour planetary camera. The best of a poor set of clips.

    From the album: Mars

    Having messed about with one of my blurry images of Mars for most of the afternoon, I may have captured the clouds over Olympus Mons or otherwise I've managed to organize 'noise' into a clump.

    A reprocess of my M100 image which is also in this album.

    From the album: Deep Sky III

    In the constellation Cepheus, at 1400 light years from Earth, lies vdB 152, a small blue reflection nebula located at the tip of the dark Bok nebula Barnard 175. Embedded in the dark nebula is the Herbig Haro object HH 450. The faint red streak to the right of the reflection nebula is a supernova remnant known as SNR G110 + 11.3 which appears to be approaching vdB 152. Some of my notes for those that might be interested: Reflection nebulas are created when a nearby star illuminates the gas of at a nebula at an insufficient energy level to ionize the gas but strong enough to create light scattering that makes the dust visible. Reflection nebulas mostly appear blue because particles in the nebula scatter blue light more efficiently than other wavelengths. Bok nebulas are isolated and relatively small dark nebulas containing dense dust and gas from which star formation can occur. Herbig Haro objects are bright patches of nebulosity that form when fast moving narrow jets of partially ionised of gas, ejected from a newly formed star, collide with nearby gas and dust at several hundred km/s. The LRGB image below represents 12 hours integration time and was taken with my Esprit 150.
