New color experiment!

Posted By Gianluca Valentini
Hello guys,

trying to get a grasp of Photoshop processing: It is incredibly complex.

However, while playing with a B&W image I tried to give it a new color (new for me, of course). I like the outcome, so I thought to share it and get some feedback from you all guys. Thanks.

DATA

Tak 102+Solarmax 90 @ F20
Lumenera LU075C at 60 fps
approx 500/1500
Iris and PS processing

Faint prominence

Posted By Gianluca Valentini
Hello guys,

eventually I found some time to go back to some old avis I took some time ago. This attached is a prominence I already filmed and posted, but I like this shot better as it highlights what I liked mostly about this prominence, i.e its faintness, ghostly appearance.

Love sun imaging 8)

Ciao guys

Luca

PS still fighting with Photoshop and I haven't yet found a way to soften the border of the black disk. I hope to get it soon :C

AR 798

Posted By Gianluca Valentini
Hello guys,

back from holidays and back to "work" grin
The seeing wasn't very inviting, but I knew that Italy would have been hit by a lot of rain in the next few days, so I took the chance.

All data are on the image. I used again the FITS export option in Streampix and captured with the 16bit option.
As usual all comments and tips are welcome.

Ciao

Dare to go beyond grin

Beatiful image Robert. Would you be so kind to give me some detail (fps, frames stacked.....)

This object is missing from my list of capture: I've gotta get me one of these blue marbles some day wink

Ciao Robert and thanks for posting this rarely seen planet.

Hello Robert,

I believe that the shots are potentially really good, but processing may need a tweak: Arzachel is a bit too dark and Alphonsus a little too blu! Are you working always on the same monitor, or do you switch between acquiring and processing?

Ciao Robert

My first CCD full disk solar image!!

Posted By Gianluca Valentini
Hello guys,

I had to try a full disk! I'm still trying to cope with some problems encountered with the SBIG ST-2000 and solar imaging, but I believe I succeded in obtaining a decent image nonetheless.

Data are on the picture. Image has been reduced to 50% of its original size. The date is Aug. 28th Approximate UTC 11.00.

Ciao all

My 1st full disk CCD image

Posted By Gianluca Valentini
Hello,
it is my 1st post here and the image attached has been already posted in the solar system forum.
It is the first image processed of a batch of 30 shots I took that day grin

Any suggestion would be greatly appreciated.


The date in Aug. 28th. UTC is approx. 11:00: the rest of the data are on the picture.

Thanks and ciao all grin

Hello Robert

frankly I don't understand your concern: I like the image! Let us say that you are just warming up before really flexing your muscles when the opposition comes wink

Full disk and raging AR 798

Posted By Gianluca Valentini
Hello everyone,
after seeing the splendid images posted lately on this solar active region, I post this :S which is not exactly at the level of Alan's, but it is a full disk and so maybe worth a look.

The image has been obtained as follows:

Tak 102+ Solarmax 90 @F8
ST-2000 XCM with a 13% ND filter
single 6msec exposure processed in PS for disk details and prominences' details and then merged into the attached image which has been also resampled to 70% its original size.

Thanks for looking

A little prom action

Posted By Gianluca Valentini
Hello guys,

the weather sucks here (some areas, including mine, had massive floodings for the copious rains), but I stocked up in the days before and I'm processing some sequences captured on Sept. 10th and 11th.

I've done some testing with exposure times: this image was recorded at 30 fps, 16 bit B&W and the exposure time was approximately 7 msec. Processed in Iris 5.0 and Photoshop CS.

Thanks for looking.

Ciao
