Hi everyone, a 9-hour session (10- and 20-second exposures) in Bortle 4 skies targeting Melotte 15 the core of the Heart Nebula. Processed in HOO; stacking and processing done in Siril and GIMP no script osc the "click and pray" approach isn't for me.. clear skies all
Hey everyone, still a long session on SH2 173, 36 hours of exposure. Started last December: 18 hours in B6 and 17 hours 34 minutes in B4 seestar s50. I wanted to create a monoha image by merging the green and red channels minus 0.5 from the blue in Pixelmath, and here's the result. I'm thinking of going up to 50 hours and then doing it in Clear Skies All color.
Hello everyone! I was lucky enough to visit Reunion Island in the Southern Hemisphere and photograph this magnificent target, NGC 6188: 686 exposures of 60 seconds in B4 mode, using an S30Pro camera specially loaned for the occasion. Processing was done using Siril and GIMP. I hope you enjoy it!
Hi everyone. I don't often shoot star clusters, but it makes for a nice change from galaxies or nebulae. Messier 13: 4 hours total (stack of 500 x 30s exposures in Bortle4 ), processed in Siril. Clear skies all
Hi everyone—no need for an introduction here: M16, captured with the S50 from France (1445 x 10s at b9 and 1680 x 30s at b2.8). Stacked and processed using Siril and GIMP. I hope you like it.
Good evening. Here is a re-processing of data acquired in 2025: 3 hours and 22 minutes of exposure on NGC 7000 (30-second subs 402x30) using an equatorial mount in a Bortle 4.8 zone S50; stacking and processing done in Siril and GIMP. Clear skies all
Hi everyone—just one quick hour on the Bubble in B9 (376 x 10s) to get a little preview before tackling a 7–8 hour session. Stack and Treatment siril
Hi everyone—just shy of 23 hours of integration time on NGC 6888 (90% of which was shot in Bortle 9 skies). The data consists of: 4,756 x 10s exposures from me (Bortle 9); 1,925 x 20s (Bortle 9), 366 x 10s (Bortle 3), and 360 x 20s (Bortle 5) from u/Cultural_Cheetah4515; and 386 x 10s (Bortle 5) from u/eukastros. I created two different versions: an Ha-OIII blend and a pseudo-SHO (Forax palette) to really bring out the blue shell. I hope you like it A big thank you to them u/Cultural_Cheetah4515 and u/eukastros for the data. Stack and Treatment siril gimp
Hi everyone: 15 hours (1,800 x 30s) of RGB data (LP filter off) on M20, captured under Bortle 2.8 skies in France; stacked and processed using Siril and GIMP. I hope you like it
Hello everyone, I'm using an M101 Harvb channel with 12 hours in ircut and 5 hours in lp, layered and stretched separately. For the Ha, I simply stretched the red channel, then removed it (star effect), and merged it with the RGB channel without stars in GIMP at 35% opacity. Treatment siril gimp clear skies all
Hello everyone, for this image, I used 20 hours of B3, to which I added 5 hours of LP, which I then layered separately. I stretched only the red channel in Siril and merged the starless layer of this red channel (LP) with the corresponding starless RGB layer in GIMP to integrate the signal Ha, while preserving the IFNs. I'm open to any suggestions.
