nicoscy Posted October 1, 2020 Share Posted October 1, 2020 Temps are reasonable enough to avoid cooking the imager - good to be back to solar imaging after summer break! 15 Link to comment Share on other sites More sharing options...
Davey-T Posted October 1, 2020 Share Posted October 1, 2020 Nice to see the Sun, no chance here. Dave 1 Link to comment Share on other sites More sharing options...
Altocumulus Posted October 1, 2020 Share Posted October 1, 2020 Nice. Lots of little dances around the rim. No chance here, either, cloud and occasional rain. 1 Link to comment Share on other sites More sharing options...
Lowjiber Posted October 1, 2020 Share Posted October 1, 2020 Nicely done Nicos. Love those inverts.😀 Thanks for sharing your work. Clear Skies 1 Link to comment Share on other sites More sharing options...

nicoscy Posted October 5, 2020 Author Share Posted October 5, 2020 Lol, should actually try to remember to orientate properly, as they are upside down 😅 1 Link to comment Share on other sites More sharing options...
Altocumulus Posted October 5, 2020 Share Posted October 5, 2020 I thought, in space, there was no up, nor down..... 1 Link to comment Share on other sites More sharing options...

randomic Posted October 5, 2020 Share Posted October 5, 2020 I notice in a lot of sun pictures there's no limb darkening. Is this due to a filter used or does increasing contrast in processing hide it? Beautiful pictures by the way, I'm looking forward to the increase in solar activity!

nicoscy Posted October 5, 2020 Author Share Posted October 5, 2020 Post processing and use of an artificial flat in Photoshop which takes under a minute to create. Workflow is not mine, it is MalVeauX who shared this: - Copy base layer and do a Noise / Dust and Scratches: 30 Radius (or thereabouts) and merge layers, then; - Copy base layer and do a Noise / Median Filter 45 Radius (or thereabouts) and merge layers, then; - Copy base layer and do 3x Adjustments / Curves / Presets / Darker, then; - Set layer to Difference and adjust opacity to find a balanced image eliminating most gradients / limb darkening and merge layers I am still a solar noob, playing around with various processing techniques, but I do think I will direct my focus to inversions. I kind of like them more 1 Link to comment Share on other sites More sharing options...
Rusted Posted October 5, 2020 Share Posted October 5, 2020 Limb darkening is more of a white light thing. Though it certainly exists in H-a and possibly Ca. It's most noticeable when teasing detail out of a poor image. It darkens the edge first as you move the sliders in ImPPG. The limb easily vanishes completely during clumsy processing. Sometimes ending with the "Dahlia effect." 1 Link to comment Share on other sites More sharing options...

Rusted Posted October 5, 2020 Share Posted October 5, 2020 Darken a close-up, H-a image enough and it turns into dark petals. Being darker at the limb makes it look as if it curving away like the flower of the same name. Link to comment Share on other sites More sharing options...
nicoscy Posted October 5, 2020 Author Share Posted October 5, 2020 Ah, I don't do closeups - only full disk images. Your scope supports high magnification imaging, mine is a paltry 60mm Lunt with the ASI178MM Still, for someone who is not willing to use anything larger than the SW SolarQuest, the 60mm and ASI178 give me some nice disks! Now, if only I stopped being lazy and try imaging with the DS module on... Something for this weekend maybe! 1 Link to comment Share on other sites More sharing options...

Planning ahead to use a DS - classic result in cloud cover..... 2 Link to comment Share on other sites More sharing options...
nicoscy Posted October 6, 2020 Author Share Posted October 6, 2020 Geoff, I need to stop being lazy and try my hand at double stacking. Filter has been sitting in its case for a year because I more or less enjoy single stack and I am lazy. But, if I want to get more detail in my images, I need to break out the DS module asap! 2 Link to comment Share on other sites More sharing options...
