Really nice Luca - and wisely processed to create a 3-dimensional look. Images that are heavily sharpened lose this, I think.

lovely work!

Hi Robert -

Very nice work on both of your recent Jupiter images!

Thanks for posting them -

RGB filter question

Posted By Alan Friedman
Hi all -

I wonder if any of you have found an advantage to a particular filter set over another for RGB imaging with a monochrome camera?

Thanks for sharing your thoughts on this.

6 inches of Jupiter

Posted By Alan Friedman
Hi -

Here is Jupiter captured through my 6" Astro-Physics refractor at a focal length of about 3.5 meters. The seeing looked good at this magnification - Jupiter was almost 34 degrees in elevation.

Plato (from a steady night)

Posted By Alan Friedman
Hi all -

I had good fortune this morning to find some steady air with the moon up high just before dawn. I processed this single stream image of Plato first as a test because I have a number of previous attempts to use for comparison. I think these conditions might be the best I have had yet for imaging the moon.

Taken with my A/P 10" mak/cass at f30 and DMK 21BF04 webcam using a green filter. 97 frames were hand selected from 400 and stacked using multiple alignment points.

It's nice to have some new work to post after a long dry spell.

best wishes -

Postcard from the Edge

Posted By Alan Friedman
Hi all -

This view stretches about 50 degrees in lunar longitude - from the small crater Horrebow that adjoins Herschel (you can connect the image to Mike's Bay of Rainbows at this point) to Epigenes and Anaxagorus (seen in shadow all the way to the right). The prominent crater with two central mountains is Philolaus. Libration was not favorable this evening for the north pole, but it would be located about 5 degrees to the right.

Made from four frames captured on August 16 through the 10" mak at f30 and DMK21BF04 with green filter. About 300 frames total were used - 80 alignment points - the image is reduced about 20% to keep the file size down.

I hope you enjoy it -

The Sea of Clouds

Posted By Alan Friedman
Hi -

Here is a view of the Mare Nubium. The home of well known Rupes Recta, the region has some other subtle but interesting features. A small rille to the right of the fault line shows up well at this low sun angle.

Captured on August 16 - I was able to find 100 good frames from each stream to use for this mosaic of five images. I processed it a little on the soft side.

best wishes -

goblin prominence

Posted By Alan Friedman
A nice bright solar prominence has been growing over the last two days.
Can you see the small Halloween goblin looking out from amidst the flames?

cheers-
