The Hedgerow Prom and Solar toolbox

Post by AndreaGirones »

A little timelpase of the large prominence located on the Southeast rim of the sun May 19th 2024.

This timelapse of 1.5 hours was processed and colourized using Bill Blanshan’s Solar toolbox developed for Pixinsight which is a new solar look for me. What do you think? I would like to have a little softer look as i am not a fan of the supersharp surface. Any ideas from anyone?

Also does anyone do solar alignment in Pixinsght. the FFT script did not work for me but IMPPG did the alignment instead.
Imaged from the backyard with hobbyist equipment including the Starfield Optics 102 ED refractor, a Quark Chromosphere solar filter and a monochrome planetary camera.

Hi Andrea,

I use ImPPG for alignment, deconvolution and sharpening, and PixInsight for refined sharpening and colouring. I’m just getting to grips with Solar Toolbox. There are some interesting capabilities embedded in this add on that I’ve yet to properly explore.

Nice one! It is very easy to oversharpen in the PI Tool Box. You need to play with the sliders just a bit more to achieve a softer image.

Looks great!! I've never used PixInsight so can't help. I really like the sharpening in ImPPG :)

When I do solar timelapses I would use Autostakkert4! to stack, ImPPG for alignment and if the seeing is steady enough I would run a Linear Fit Batch Process on all the frames to address any variance in brightness. Also, if you want to get really 'Hollywood' on them then the free video editing software Davinci Resolve has some nice features but a steep learning curve. There is a Youtube video out there in the wild where it was used for solar timelapses.

I have used the Solar Tool Box on past and current images and to be honest it's not for me. I like to invert my images whereas the designers of the tool specifically built it to keep proms and surface detail in the same 'phase'. I know that it has an invert option but ImPPG gives much more control. Also, I prefer grayscale images as I personally feel colour 'hides' a lot of detail.

The 'standard' sharpening tools in PixInsight are good. However, the Restoration Filter tool is overlooked as a method of introducing detail into your image. Keep the aspect ratio as 1.0 then reduce the shape to around 0.6 and play with the std deviation around the 0.3 to 1.0 mark.

BlurXterminator works to if you have it. I reduce Sharpen Stars to 0, switch off automatic PSF and set the manual PSF diameter from 1-5 then adjust sharpen non-stellar to taste. Again NoiseXTerminator can help in very small doses.
