Antares and Rho Ophiuchi Regions Taken over several years. Twice in Spain and twice in East Sussex. Spain 2017 DSLR and cheap camera lens and Ioptron skytracker. 4 hours Spain 2019 same set up but with a luminance filter and Mono CCD camera 2 hours I wasn't happy with either as the cheap camera lens produced horrible stars. Having bought a Samyang 135mm lens at the end of 2019, I decided to try to get better luminance from the campsite I visit from time to time in East Sussex, but it is VERY low from the UK. This time I could take my full rig with me and do longer guided subs. HEQ5, Atik460EX and Samyang 135mm lens. 2022 I captured some luminance with better stars of the Antares region, but half of Rho Ophiucci was chopped off. 1 hour 20mins https://www.astrobin.com/sz1393/B/ last week April 2023 I captured the area around Rho Ophiucci and made a mosaic thus completing the image at last. 1 1/2 hours. Of course we can always use more data but given my VERY limited opportunities I think this will be the final version. Total of 8h 50mins Link-words: CarolePope
