Hi Alfred, I took a liberty to process your image a bit further. Here is the result. So, your seeing is even better and the setup has better potential than it seems on the first glance. Right click on the image and open it in a different window to see it in a full resolution. Valery Thanks Valery f...

Re: 17Nov19 3-Band FDs and HR Images

@mauritus,

The CAK images are great. - I am still experimenting how much deconvolution and unsharp masking to do in imPPG. I like the soft version better.

Brilliant images, Active Region that was assigned AR2752 now with filament as of 18th November 2019.
Thanks Stardust. It is very cloudy both yesterday and today. I didn't have the opportunity to see the the filament. Hope to catch it soon.

The mosaic was seamless! What software did you use to

1. take the 9 images
2. stitch them into 1?

Re: Sol from the 16th of November 2019.

Hi Eric,

That is a great harvest! How long did you spend to get all of that? I especially like the proms with 2 shades. I must say I have only recorded proms with 1 shade of grey. How did you do it?

Re: FD on November 16

Nice catch, Franco. I waited 2 hours for the clouds to clear on 16 Nov 19 and gave up. It cleared 2 hours after that. The following day I got some average images. Hence I am always happy to get something, even poor quality images.

The Active Region that was assigned AR2752 on 13 Nov has moved inwards and also grown smaller. By today, the small spots were no longer visible in WL and G-band. The plage is however visible in HA and CAK. https://1.bp.blogspot.com/-4yUnwo2gyDk/XdFQXfGjIAI/AAAAAAAAoUM/9dntDq96SY0tHilNhs_WMpLdvI_UFqC...

Yes, all equipment, except the PST etalon that is used for the last image is functioning well. I was not able to have uniform featues with repeated tuning of the etalon. May be its internal gasket has been deformed or something. Previously it was ok. Doing some investigation.

Re: 2 Nov - 3-band FDs and zoom-ins

Thanks Eric and Alexandra.

It is interesting to see the differences in the HA-CAK plasma structures. I hope to do more of such high-resolution images comparison. Will include G-Band in the future:)
