Plato

Posted By Alan Friedman

Hi all -

I love this crater.

Someday we are going to have a date together in fine seeing - but, alas, it was not to be on April 19th.

How I want to sharpen this more - but there is no more signal to sharpen without introducing noise.

275 frames stacked from 800, seeing 5/10. 10" A/P mak, 2x Powermate, R filter with IR blocking, DMK 21BF04 B&W webcam.

cheers -

A wider field image taken the same night as the Plato close-up. Same set-up but at prime focus of my 10" Mak.

Exceptionally nice - among the best I have seen!

IT'S ALIVE!

Twenty minutes of images taken of AR756 on Sunday, May 1st centered around noon.

If you've ever wondered why it is hard to composite many different streams for a high resolution solar image, I think this helps explain it!

Finally - a night of good seeing!

Posted By Alan Friedman

I hate to post a quick preview - but it will take me days to look through the 5 gigabytes of RGB streams I took last night in good (7/10) seeing and I am just plain excited at finally having had a steady night for Jupter. Elevation was about 42 degrees at 9:54 and I didn't even need to refocus between filters!!

A fast processing of one of the red streams (for some reason, It seems that the green filtered streams were a little sharper last night) I hope I can manage a good color image or two from this material.

best wishes -

OK - I think we need to do drug testing on this ETX!! wink

Congratulations on your very fine captures of this exciting sunspot -

Jupiter in good seeing

Posted By Alan Friedman

Here is my first completed image taken in unusually good Buffalo, NY seeing conditions May 4th.

DMK 21BF04 B&W webcam - 500 frames total through red and green filters used for the luminance component. Astro-Physics 10" mak/cass with 2x powermate.

Jupiter composite (final)

Posted By Alan Friedman

I completed three sets of RGB streams from my good fortune on May 4 - covering just a little more than 1/2 hour of rotation. Shown slightly reduced so that all 3 can be viewed without scrolling.

Now I am ready for something different (whew). 8O

steady skies!

Re: Jupiter May 9th, 2005**final version**

Posted By Alan Friedman

Hi Eric -

Nice work! I prefer the processing in the first version. Were they both done from the same stream?
