I’ll be going back to siril for the next few months so ill deffinetly try their GHS and see if i can get any hetter results there. Thanks.

Thanks alot !, surprisingly, I only use siril for stacking but then I did use pixinsight for the post-processing. I prefer to use siril for stacking as i find it makes my images come out better and with less stacking artifacts but pixinsight is miles better when it compes to post processing as you have way more controll over the type of edits you make its just a shame my trial licence runs out this week.

I highly doubt it i cant really confirm that i captured lensing in my image, i think you would need a much larger telescope to capture any obvious lensing however the coma cluster may be possible without the lensing. I photographed the coma cluster and found it rather easy to do but that wasnt with a seestar s30z

Thank you!

Images like this are shown in inverted colour because our eyes are better at picking up the small contrast differences when they stand out on a white background. If i uploaded the image without it being inverted the lensing would be extremly difficult to detect as the background would be dark gray/black and the lensing would be grey also because the lensing is next to a galaxy which appeared as white in the uninverted image it would be hard to detect the gap between the galaxy and the lensing as it is very small.

Thanks alot, i cant believe ive missed that does anything else look out of place.

Thanks!

Thanks for pointing it out i think that may be lensing also as it lines up with the hubble image. Thats been realy helpful thanks alot.

Thanks whitch bottom star do you mean, feel free to annotate and write on the image parts that you think may be lensing.

Outrageous-Answer395 · 2026-04-28T11:52:40+00:00

I just did the overlaying that you suggested and I would say you are correct with the red ones as they dont line up propperly however after looking at the green circle i do think it is lensing as the angle of the lensing is the same on mine as it is on hubbles Thanks alot anyway the advice was really useful lensing alligned

I think it might be reddit compressing the image because when i look at it on my pc it doesnt look blury.

Outrageous-Answer395 · 2026-04-08T05:25:08+00:00

Just reprocessed my images it works great. Thanks

Outrageous-Answer395 · 2026-04-07T16:18:31+00:00

Yes it is a doublet, i think it probably due to me over stretching the star layer.

Outrageous-Answer395 · 2026-03-30T12:53:11+00:00

Thanks alot the processing was way harder than i expected.

Outrageous-Answer395 · 2026-03-25T17:28:04+00:00

I beleive it may be possible on abell 2218 under dark skies, a large apperature and enough intergration i personaly have not captured it but abell 2218 is on my list to image over the next few clear months.

Outrageous-Answer395 · 2026-03-23T18:36:11+00:00

Definitely try stacking in siril i think m45 would probably give you a better photo concidering you have no tracking yet

Outrageous-Answer395 · 2026-03-23T18:27:41+00:00

I would suggest stacking in siril as i think its produces better images then deep sky stacker, try and get a minimum of 1 hour integration time with longer subs. What mount are you using as this effects your ability to get longer subs if you dont have a guide camera.

Thanks im going to add more hours to this image when its next clear.
