Re: 11th May'21 image - processing-request idea please ?

I hope this helps Terry, I sat and worked it out in GIMP Merging surface and prom in GIMP • Open both images • Work first on the CaK image: • First remove all writing from the CaK image with the brush tool set to black. • Image – scale image – type in size so similar pixels to the prom image • Then ...

Re: My first large-aperture Hα image – processing ideas

200mm_ha_01_.jpg I've not done as good a job as you :( I just used LR deconvolution in ImPPG. You have the same problem as me, the stack shows only areas of detail and the rest in blank. I get this all the time and I presume this is bad seeing. All my images with the C11 have only one small area of...

Re: Full Disk Mosaic in Ha with AR12822 and AR12823

Well, there is a simple answer to that but you have to look very closely. According to Zirin (Astrophysics of the Sun) p 174 in the blue wing the spicules are doubles called 'twinning'. In the red wing the spicules are singles. That is the only way I know that you can tell. I need to scan in the pho...

Re: CME Impact 12th May 2021-UPDATED

Looks like the Aurora alert was a bit late coming at 6pm, looks like the peak was earlier at around 12-3pm. Still no good as daylight hours, would have been good for the penguins in Antarctica though :)

Re: 11th May image - further processed - request please ?

I think it is a great image Terry, you are doing very well, all the proms look lovely :bow :hamster:
Peter's method looks very good above, you just need to find the equivalent in GIMP

Re: Full Disk Mosaic in Ha with AR12822 and AR12823

If you look closely you will see dark rosettes of mottles across the disc, they are flat and dark with white patches between. If on band the mottles would be 3D in structure and fluffy with no obvious white patches around, the surface would be more uniform and stuck up like grass. Very hard to descr...

Re: white light comparison

No good for what Mark? bad quality optics or just wide band? My Baader K line is permanently just out of focus, it works OK as a blocking filter for the PST at prime focus but when you use a 2x Barlow it is back to blurred. This one is 10A narrower and could be in focus and is much cheaper, that cou...

I found this in the 'Solar Reference Library' https://solarchatforum.com/viewtopic.php?f=7&t=13884 It is for Photoshop but in all 3 programs (Photoshop, GIMP and Paintshop) the principles will be exactly the same. You just need to find the equivalent feature in the others. I have GIMP at home so...

Re: AR2822 mid flare

Being picky, with the flare image, I would overlay it over the original and blend in the original flare (unprocessed in sharpening). It would bring it back to pure white and remove the bad ringing. It kind of spoils the look in close up. Hopefully you will know what I mean, all in a good way of cour...
