Sun-One of my best!

Posted By Gianluca Valentini
I tried manual selection of this sequence captured on April 4th and the difference with the result of automatic selection is, to say the least, dramatic. I wish I always had the time and patience to do it sad

Equipment is always the same and the other relevant data are on the image.

Thanks for looking

The sun...NOW!

Posted By Gianluca Valentini
Hello guys,

I'm sick at home, but that didn't keep me from peeking at the sun. I noticed that there was this monster prom going on and so I gave it a try although it was a bit too windy and the seeing was truly bad. I selected manually the best 106 frames out of 1500 (terrible job sad ) and here are the results. I post two version: one is the traditional way of processing proms (at least mine) the other is its negative image (without the masking of the disk because unnecessary).
The time of this image is UTC 12:29 so less than 5 hrs ago at the time of this post grin

Which one do you prefer? I still prefer the "standard" B&W appearance, but that's me.

Ciao all

Luca

PS sorry guys for flooding the forum with sun images, but this is, after all the solar system forum and these are shots of the BOSS itself!

My attempt at Copernicus

Posted By Gianluca Valentini
I had a good evening a few days ago and I snatched a couple of moon sequences. This is the first one I process and it may well be my best lunar picture so far grin

200/3000 frames. April 9th 2006 UTC 22:22
Ciao guys

The solar show

Posted By Gianluca Valentini
Hello everyone,

the sun is really giving out a great show these days grin . As you can see from Mike's posts even today has been a very busy day for our star

This is a shot from yesterday. I have a few movies and this is the first one: I hope some of the others will yield better results, although I'm quite content with this one smile

First light..white light!

Posted By Gianluca Valentini
Hello guys,

the sun is preparing a new active area grin

Here is the first light of my new Herschel prism. I have others but this is the first in combo with the same area in h-alpha.

I hope you like it: I know I'm having a lot of fun grin grin

PS this is 70% of original size

Damn the rain!!!

Posted By Gianluca Valentini
Here it's pouring :C
Meanwhile the active region 875 is putting up the best show and we've got no tickets!!!! I suggest anyone who's interested to check out Greg Piepol's site for a nice little movie of the C8 flare that this area produced yesterday (here: http://www.sungazer.net/video/video.html ).

However, I'm still processing some movie of the 24th, the last clear day we had here in Italy. Here is another one of the rising 875 with some proms in the back. The quality of the picture itself isn't that good, but the view is quite dramatic grin

Ciao guys

My best Plato ever!

Posted By Gianluca Valentini
Hello guys,

I had a lucky night with the moon on April 9th (that's when I took also my best Copernicus which was also my best lunar shot).

This is Plato and it is by far my best Plato. I can count all the 4 craterlets mapped by Virtual Moon Atlas grin I can actually count a 5th one on the far left side!
I have a couple of wide field shots of this area that give me hope for something of similar quality but BIGGER, but I will process them very slowly to keep something to do for until the gloomy weather ahead of us endures sad

Ciao

Another prom from april 21st

Posted By Gianluca Valentini
Hello everyone,
this is another prom that I have already posted but from a different sequence captured. Even the processing is a bit different.

Hope you like it

All solar info in a nutshell!

Posted By Gianluca Valentini
Hi everybody!

I just thought to post this info for everyone who's interested in having all the solar info in a single page: the Catania Astrophysical Observatory (this page http://web.ct.astro.it/sun/ ) posts everyday (when possible, naturally) the latest solar images in h-alpha and white light. The site is in English (don't ask me why, since it is in Sicily wink ) and the latest images are right there in the opening page. There is also an interesting drawing of the full disk and all its spots with their name and classification.

Just thought it would be interesting to all solar observers and not out there.

Ciao

Noaa 0875 is fading away!

Posted By Gianluca Valentini
Hello guys,

the 0875 is definitely a goner grin

It is also the only interesting subject in H-alpha today.

I was able to "steal" some time at the telescope for my lunch break and I captured some frames. Alas, the seeing was truly bad and I don't have high hopes for the movies I have. The one attached seemed to be the best.

Ciao all

PS I just realized I forgot to include UTC in the image. It was 12:00 UTC.
