Nothing to write home about, but at least I got something visible 😀

I somehow managed to mess calibration frames so much, that darks were apparently brighter than lights (at least Siril told me, that 37% pixels after dark substraction had negative values, and result had indeed some strange all-black areas. No, I hadn't subtracted bias twice). So I had to toss the calibration out. And the noise is overwhelming. And it was shot under Bortle 6 sky. And there was moon. And I suppose I should have opted for lower ISO and longer stack. And there is coma, that was only accentuated by deconvolution, so I skipped deconvolution also. And … But!

Lumix G80, Olympus OM 300/4.5, no tracking, 152 frames stacked (out of 180, I really need a better tripod).

#astronomie 9 mètre de focale c'est beaucoup (T200 à F/45 😂 ) faut vraiment avoir peu de turbulence, jusque minuit c'était ok mais après #jupiter était trop basse ou trop près de la maison (qui dégage de la chaleur ...) dommage, seul la première image du transit d'ombre est correcte. A droite les deux satellites IO et Ganymède, Europe est superposé à Jupiter et son ombre se projette sur le limbe opposé camera #zwo #ASI662mc, projection oculaire 15mm, traitement #siril

The Year Lot Longyear Became a Joshua Tree
~~~~~~
Half the Park is After Dark. A magical winter night in Joshua Tree National Park. I love partially cloudy nights. To create this night photo, I lit the subject with a handheld LED flashlight while the camera shutter was open for a long time. So yes, this is a real single-exposure photo. And Lot Longyear is thought to be the bent figure on the cover of "Led Zeppelin IV."

I remember seeing the Horsehead nebula in my parents’ encyclopedia as a kid. I was amazed at how such a thing could exist. And now technologyy has evolved so far, that I can take the same picture from my own backyard! Here it is accompanied by the Flame nebula in the lower left together with the star Allnitak, which is the left most star in Orion’s belt. #horsehead #B33 #NGC2023 #horseheadnebula #flamenebula #astronomy #astrophotography #deepsky #backyardastronomy #astroshots #astrophoto #Space #universe #galaxy #universetoday #nightsky #stars #galaxy #nightphotography #skywatcher #touptek #backyardastrophotography
