Simple solar limb imaging - capture and process

This is how I do close-ups of the solar limb with my 40mm Lunt and ZWO ASI174mm - including a Powermate/Barlow, and using IMPPG for processing!

Thank you for another excellent tutorial. I always find your tutorials easy to follow and very helpful.

Thanks! That’s really nice to hear.

Thank you for showing your process

I have just photographed the Sun in white light using Baader Solar Film and a 25 mm Pocket Borg refractor and loads of big sunspots .

awesome catch! like the processing also! well done. thanks!

[@CellistOnTheRoof]

Thank you too!

[@WSS_the_OG]

Incredible! I have always been terrified to try this myself. Well done!!!

[@CellistOnTheRoof]

Thanks! You should go for it, now’s such a good time!

Hi Ivana,
That's a great tutorial! Just a note - if you keep the selection box small for your initial fine-tuning, you'll see L-R changes in real-time as you move the slider (and you can always draw the box around some other region of interest in the image).
Also, since Feb last year, ImPPG can process RGB images (I've been using it on Jupiter to good effect) - go check out the latest version.

Thanks very much, all very good to know!

Cool! Sun is so interesting in hydrogen alpha.

[@CellistOnTheRoof]

Thanks, yes I think it’s absolutely mesmerizing!

Nicely done once again! Another thing that can help with Facebook compression is to save your images as PNG files. This doesn't always work but more often than not gives you a better result.

[@CellistOnTheRoof]

Thanks! Yes that’s absolutely true. I do all my planetary in PNG but for some reason found the IMPPG PNG output a bit funny. Maybe I’ll find out down the line I’ve been doing something wrong all along 😄

[@petesastrophotography]

@@CellistOnTheRoof Aha, OK, I mainly use Pixinsight for processing and creating the final image,. I also use Gimp and have noticed that the PNG's created by Gimp and Pixinsight can be quite different.

I miss my solarmax 60

Thanks for the guidance on how to take and process hydrogen alpha images. As always your posts are interesting and helpful to aspiring astrophotographers like myself. I enjoy your presentations and always come away with new knowledge that I can put to use. Looking forward to a great summer of astronomy and more of your posts.

Thank you for sharing this useful info, I'm currently thinking of getting a 174 for my Lunt LS50 as the 290 I'm currently using doesn't give a full solar disc. Nice image by the way.

[@CellistOnTheRoof]

Thanks, really pleased if it can be useful! You’ll love the 174, it’s great.

Quality graph not to bad !!!! Wow I rarely get 100f over 75% out of 20,000

[@CellistOnTheRoof]

It’s rare but it does happen! I think late morning is best time, high in the sky but before the air gets too hot.
