Sh2-129 Squid Nebula (HOO with RGB stars) from multiple nights in 2022. 29hrs of data gathered. Some of it very difficult to process as the ZWO 7 Nm OIII filter allowed the brightest stars to bloat horribly. The blue nebulosity behind those bright stars has been lost in the processing. I am making a case, to myself, for the purchase of an Astrodon 3Nm OIII filter because I have other targets whose data could…

Since 1950 many people have loved being flies on the walls in Ambridge to hear the drama and gossip of several families in The Archers that don’t actually exist. The genealogical roots of many celebrities have been investigated with a fine tooth comb over the years in…

Mark Godwin captured an extraordinary image of the ISS crossing the Sun on July 27, 2024, at 15:24:46 UT using his new ZWO Seestar S50 Smart telescope. The impressive still was extracted from a 4-second video sequence….

Multiple milestones in astronomy have reshaped our understanding of the universe: from Apollo 8’s Earthrise photo to Copernicus’ heliocentric model, Galileo’s observations, Hubble’s expanding universe, and Penrose’s cyclic cosmology theory….

Dean Ashton discusses his two-month exploration of a new approach in PixInsight for comet processing, combining the PI Comet Alignment and StarNet2 processes. He explains his workflow and details the composition and colors of various comets captured with a Nikon Z6 camera….

Last night I tried a widefield approach with the camera gear I already have. I used the Laowa macro lens at 100mm and F4 capturing 2 hours at ISO 800. The EQ mount was an Explore Scientific Iexos 100 PMC Eight. No calibration frames used in WBPP in PixInsight. There was plenty of coma creeping towards the middle for quite a distance, A little of this has been cropped but the remainder has been…
