Re: AR12833 in H-alpha

Thanks, Peter, now is much better! I don't have PS, I am using GIMP but the gradient tool is complicated, I don't like it.

Re: 1h Animation of many solar activities, 17 June 2021

Great animation, you have done an excellent work. I follow the same steps for my own animations but I use GIMP instead of PS for generating the gif.

AR12833 in H-alpha

This spot is still very prominent but doesn't seem to be evolving beyond the present stage. It's a nice view in white light because of the well developed penumbra and in H-alpha too as it is surrounded by several filaments. Below is an image I took with my usual setup, since I was in a hurry I compl...

Re: Answer by LUNT re: Hazy area on front internal lens of 130MT

Be very careful in dismantling that kind of objective. Lenses in triplets are usually held on the optical axis by means of radial screws on the the cell that push on the lens edges, check if this is the case by removing the dew shield. If yes, you will need to loose these screws before to remove the...

Re: Heads Up 5th June

I usually apply the gamma in post-processing, use little of it in H-alpha as it helps while focusing. I think it's only a matter of personal preferences.

Re: Heads Up 5th June

Fine image, Nigella. Noted you keep the gamma all to the right, is it just for this picture or is it your normal practice ? I usually disable this function while taking the video.

AR 12827-12829 - Halpha

An inviting day for solar imaging with quite still air. AR12827 still looks interesting but seems now decayed compared to few days ago. In white light is disappointing but in H-alpha is a different object. Same for AR12829.

Modified Celestron XLT 100ED, ASI 178MM. Thanks for looking.
