Saturn Ring Spokes...Probable Artifact

Posted By Alan Friedman

Jim -

On shmutz on the CCD, my Astrovid camera use to have a terrible time with flecks that came off the metal 1.25" nosepiece everytime I unscrewed it, or screwed in a filter. A small can of compressed air is helpful, though sometimes a gentle swipe with isopropyl alchohol was needed. Wasn't as much of a problem with the planets which I could usually adjust position on the chip, but a bear for the moon and sun illuminating the whole chip.

First Ha Solar Image

Nice first image! Looks like your set-up is working well. I had a lot of trouble with interference patterns between the Coronado filter and the filter over the chip on my Nikon DSLR. I don't see this problem in your image.

Look forward to seeing future images.

Sometimes its a challenge to keep having fun while waiting for those elusive excellent nights! That's a fine image for soft seeing.

Re: firewire cams: advantages/ disadvantages?

Posted By Alan Friedman

Hi Wes -

I was just looking at these cameras this morning. The developers at AstroIIDC are working on writing control software for these - they look very interesting. Firewire used to be all the rage a couple of years ago - but with USB2, firewire peripherals are in very short supply.

Jupiter 2/22

Posted By Alan Friedman

Hi Chris -

Fantastic details visible. This image looks a little less crisply processed than some of your others - I like this one better (spoken by someone who has to tie his hands to the chair arms when it comes to unsharp mask smile )

Very nice work -

Alan
