July 22 TSE full report

Welcome Emmanuele,

nice to have a fellow countryman in this forum!

I believe that things that regard the sun belong here, but I'm not the moderator. If they kick you out, then I also have to change most of my posts, since my main interest is solar imaging and I post whatever I can here.

I will check out your website right now 8)

What a pleasure to have you back Dietmar!

Great image and great set-up you have put together with the TAO.

I'm sure we'll see some great stuff coming from that location.

adding L to narrow band (?)

Posted By Gianluca Valentini

Hello Charles,

I once asked a similar question to Richard Crisp and he thinks that adding a proper luminance layer to narrowband images makes a lot more sense than using the H-alpha channel as luminance as most people do.
I think it came out really good!

Ciao Charles

Active Region 1027

Hi Jim and congrats on this nice capture! Sorry for the ones gone bad: I know solar imaging can be as frustrating as it is exciting at times wink
Would you be so kind to specify all the equipment used for this image: scope and relative focal length, aperture of the ERF and free aperture of filter, camera and whatever info you can add.
As regards putting together proms and disc exposures, I found this document by Paul Hyndman very useful in learning some of the tricks of solar imaging. If you don't know it I suggest you take a look at it and I hope you'll find useful tips. The last pages talk about the problems of putting together disc and proms images and, although the image processing software explained is Image Plus, you can translate the operations into PS quite easily.
