Please forgive me to not double post and instead just providing a link (I hope this is OK), but I thought this may be interesting for some people here.
I had posted about about my original Corona observations last November, and finally I had the chance to go out again and repeat this week:
https://www.cloudynights.com/topic/7701 ... n-finally/
In the mean time, from lower elevation, I have made some prominence observations as well. Here I describe an observation of prominences without a filter
https://www.cloudynights.com/topic/7569 ... ominences/
and prominences in different spectral lines, this time in color
https://www.cloudynights.com/topic/7571 ... -in-color/
During this time, I have also improved my small 1" instrument which I post about here, showing some prominence images as well
https://www.cloudynights.com/topic/7638 ... ronagraph/
Anyway, I hope this is interesting to some

Hi
Very interesting.
What commercial coronographs are worth looking out for?
Cheers. Andrew.

Re: Corona and other things
Well done Klaus the corona pictures are fabulous, especially the overlays
I could do this with my Baader Coronagraph, if only I had a very tall mountain of which we have none in the UK

Re: Corona and other things
Klaus,
Very nice! I am glad you posted this. Amateur coronagraphy is something that is open for grabs. So few amateurs even attempt it. High mountains and dry air do help though!

Thanks for all the replies!
> What commercial coronagraphs are worth looking out for?
I do not think there are any commercially available units anymore. The Baader unit was last made 10-15 years ago, and Beloptik seems to have discontinued their similar unit as well:
https://beloptik.de/en/solar-coronagrap ... ce-viewer/
I am not sure if either one would show the Corona since they were really designed for prominences. But it would certainly worth a try - but one would need a proper filter to even attempt it.
