Corona season has indeed begun, and I was able to see and capture the bright Coronal loops from last Thursday (9/29) from my house in upstate NY at an elevation of 952ft with my one 1".

 

The image itself is not that impressive, which is to be expected from a low elevation site with a small instrument during warm weather (note all the insect trails in the image). However, it provides a nice closing point to this thread  https://www.cloudyni...ll-coronagraph/ where I describe the instrument and some prominence pictures, proving that the 1" is indeed capable showing the Corona as well.

As always for the 1", I used my mono IMX249 with 1/3s exposure time and 22dB gain.

This is the SDO image from the same day at the same time for comparison.

Great job, Klaus! I mean those loops are clear and this is a 25mm scope from not-too-high-elevation and not-so-clear-atmosphere.

 

The 5303A filter is special purpose and there is work debugging the light scatter, but it is clear that coronal viewing is broadly feasible.

Thanks for posting the pics! Solar viewing and imaging is so very interesting and rewarding! So many ways to observe the Sun in different wavelengths. And it changes every day!
