I got the AP-900 out to the desert, but of course forgot the adapter to attach my focuser to the NP-101. I don't have the hang of mobile imaging yet.

I did have my DMK camera and the Moon was dominating the sky. I'm often amazed at how much difference the Moon makes in a dark sky. In the city, the relative increase in sky glow is hardly noticeable.

This is a mosaic of three images, each about 600 frames of 1900 stacked in Registax. It was combined in Photoshop, but all other processing was done in PixInsight (no wavelets in Registax either).

A larger and less compressed version (http://obsballona.net/coppermine/displayimage.php?pos=-71) is on my web site (http://www.obsballona.org/).

That's nice and sharp! Seamless as well. All my attempts at mosaics of the moon show horrid seams as I can't come close to processing each tile the same.

Rick,

I've been using the photomerge capability in Photoshop CS2. It isn't perfect, but it does a decent job of merging the images.

A Super fine image and very detailed and sharp and did an outstanding job in this mosaic. You did great Andy which model of the DMK camera you have? Clear Skies my friend and congrats on your new mount.

Excellent detail and clarity Andy. I agree with Rick, knowing how challenging mosaics are increases my respect for the image.

Efrain, Kent, and Mahesh -- thanks!

One trick I learned on the mosaics is that in Registax, on the stack dialog, there is a "stretch histogram" option. I always make sure that is not checked. In addition, I stack the same number of frames from each image in the mosaic. This helps keep the final image looking similar between frames. Of course, on capture, exposure is manual and set the same on all images. I also do not do any sharpening or other changes to the images until the mosaic is created. (OK several tricks :) )

Efrain, I have a DFK 21AU04.AS -- color USB camera, 640x480.

Clear skies,

--Andy

I tried to do the analysis of your image, but the large image can not curtail to show the exact locations on the moon, hence the following think I am attaching.
