880 & 881 in h-alpha and WL

Posted By Gianluca Valentini
Hello guys,

I just wanted ot post these 2 images before going to bed (I've been trying to get some Jupiter but the seeing was so bad I'll end up trashing all the movies I captured sad )
However I was able to get some sun images yesterday. Not so good as the seeing was truly miserable, but at least they're something!

Both were captured at a very short focal (approx 2000mm) to reduce the effects of bad seeing and also to be able to fit both areas in one single frame.

The h-alpha is 100/1000 frames captured on May 6th at 11:49 UTC; The WL is only 50/1000 frames (the rest were unusable) and was captured at 13:52 UTC.

Copernicus

Posted By Gianluca Valentini
Hello guys,

here is another Copernicus that I judged above my standard lunar images. I could sure use a bit of advice on processing here smile

Plato widefield

Posted By Gianluca Valentini
Hello,

I've been trying to get a better result for a while with this picture, but this is, for now the best I can. There is a part that I cannot get as sharp as the rest (right side of Plato)It is though a work in progress, so expect a possible improvement in the near future.

Prominence today: F22.5

Posted By Gianluca Valentini
Hello guys,

I stole some time from work today and I was able to take some avis of the main prominences present today (only 2). This is the largest today at the time I imaged (UTC11:42).

I experimented different focals: this one is the first and shorter focal length, F22.5 approximately equivalent to 2050mm (Powermate 2.5).

Hope you like it

May 7th: old but not posted yet!

Posted By Gianluca Valentini
Hello guys,

I've had some time to go back and process some sequences I captured on may 7th. Some of them had an exposure problem (too dark sad ) but after a few attempts I was able to partially recuperate them. Relevant data on the picture.

Re: Msg to Mike: my dogs!

AR 10884 &10885

Posted By Gianluca Valentini
Hello guys,

here is the 1st decent shot I managed to capture after a few days of beautiful weather but dreadful seeing conditions.
Yesterday it was still windy, but it was gusty and not continuous and the seeing was much better than the previous days (I trashed more than 20Gb of files because they were not even worth processing!!), although still far from good sad Daytime imaging can be frustrating because the seeing is usually even worse than at night :C

Yin&Yang

Posted By Gianluca Valentini
Hello guys,

this is the only prominence that was worth the effort of filming yesterday. This is only 35 best frames of 1000 because the seeing was truly bad and could not save any more than 35. I hope in hte next movies to find more.

Which one do you think shows more detail? the B&W or the inverse color one?

Ciao

Seeing forecast for Europeans

Posted By Gianluca Valentini
Hello everyone,

I wanted to share this link with everyone who doesn't know of it: it is the website of the University of Basel, Switzerland that has a section that is dedicated to the seeing predictions for astronomy. Alas it is only for Europe. The info was given to me a while ago by Paolo Lazzarotti, who also told me that he doesn't trust their forecast for astronomy and that he uses the site only for the jet stream forecast. However, I found that it is pretty accurate. If you take the time to check the raw data, they present there the predictions based on 2 different models of seeing. It is at least interesting to have.
Here it is http://pages.unibas.ch/geo/mcr/3d/meteo/index.htm
Hope you will enjoy it

Ciao
Luca
