Hi Stefan -

This really is a beautiful image. I smile at your discipline to leave the rough edges at top and bottom. I always struggle with this, hating to lop off good data for the sake of aesthetic. But I think I am one of those pretty picture guys that sometimes get bad press!

Hi Mike -

Good to see a post and new image from you!
That Baja location looks like it might work for astronomy? 8)

Two more McNaught

Posted By Alan Friedman

Thanks for sharing these close-ups - they are a nice change of pace from the (many spectacular) wide field images.

Mare Frigoris

Posted By Alan Friedman

Hi Richard -

Very unusual shot - I like it!
It looks familiar. My backyard has been a mare frigoris for months now.
Here's to a better month of February...

Hi Stefan -

A nice image and interesting discussion on it in the lunar forum. I very often have my DMK camera set to a gain level around 900 (all of the streams captured in my August session were at gain=903). My workflow is different, but I find it OK to work with a stack of 100-150 frames, keeping the tolerance for sharpness quite high. I think your thought to use a green filter might have been helpful here. But a very good result nonetheless.

Last lunar images from 09/14/06

Posted By Alan Friedman

Hi Wes -

I'm sorry to see the end of these September images. The last image is my favorite of this group but they are all extraordinary. We seemed to have overlapped a bunch of targets at a very similar sun angle between your September session and the good seeing I happened into in August. I have one region left to process - Pitatus. Kind of like a really good bottle of wine, it's not going to be any fun to get back to the cheap stuff!

I hope you don't have a long wait til the good seeing visits you again.

cheers-
Alan

Congratulations on a very nice saturn. The brightening of the rings around opposition is well shown.

Thanks for posting it -

Saturn Seeliger Effect(?) 2007/2/8

Posted By Alan Friedman

Hi Richard -

The brightened aspect of the rings is shown very well. The saturation seems a little stronger than natural, but I don't mind seeing the turquoise north emphasized.

Congratulations on a nice capture near opposition - I don't think it is going to happen here.

best wishes -

Jupiter 02/13 Oval BA and STrD-1

Hi Chris -

That's a beautiful image.

Looks like we no longer have an equatorial zone - just one huge North/South Tropical Belt?!
