tonioche

thanks David, i was using unity gain (139) and offset 50.

hi all, here's an image i took last month from my usual spot in the south of france. here is the link to full res version: https://astrob.in/417237/0/ i imaged it with my 8" newtonian from skywatcher. here are the details : mount skywatcher eq6r imaging cam: asi1600mm cooled at -15c guiding cam: asi290mm on zwo OAG coma corrector TSGPU zwo filters LRHaGB L: 65x180sec=3h15 RGB:3X20X180sec=1h per colour layer Ha: 14x300sec=1h20 i mixed the Ha layer with the red layer in post process. processed in DSS, photoshop. clear skies

hi all, here's a little image from couple of weeks ago i shot from my usual observing site at the côte d'azur observatory in the south of france. that's the galaxy cluster abell 2151 in hercules. i imaged it with my 8" newtonian from skywatcher. here are the details : mount skywatcher eq6r imaging cam: asi1600mm cooled at -15c guiding cam: asi290mm on zwo OAG coma corrector TSGPU zwo filters LRGB L: 48x180sec=2h24 RGB:3X20X180sec=1h per colour layer still have a few issues to sort regarding the coma corrector but overall happy with the result. here is the link to the full res version: https://astrob.in/412992/0/ clear skies everyone

here's a version with a little bit darker background. 😉

i'll agree with you on that one. i didn't measure it to be honest, just did it visually and it really depends on the screen you're viewing it on. it's the skywatcher 200 f5 TS Optics GPU thanks a lot for all your comments guys

hi all, here's a little image from this weekend, taken with my newly acquired 200/1000 newtonian. i shot it with an asi1600mm and zwo lrgb filters. i used individual 180 second exposures and stacked them in DSS, then used siril to assemble the rgb image then processed it in photoshop. L: 40x180sec RGB:3x18x180sec mount: EQ6R guided with zwo OAG and asi290mm mini i like this triplet with lots of distant galaxies in the background. clear skies
