Hi Alan,

Thanks very much!  Keep an eye on that image as I was too tired to go through all the actual RGB components and colored it from a past image.  I am processing the color components now so we'll see what difference it makes, if any.  I ended up going back to IIDC for all alignment and stacking after first prealigning and hand picking in KIS.   

Although seeing was good here over the three days, it was still rough in the way that images distort (like rippled water).  For the moon, hand picking the frames seems to be working the best but is going to take large amounts of time :(.  When you created your Plato/ Alpine mosaic, did you hand pick the frames for your stacks?  I have a similar mosaic, although of a different area, that I'm working on.

Hi Eric - 

I see that you've added the color to the image - very nice!

I also find an advantage to hand selecting frames when working at this image scale.

Look forward to seeing your other pictures.

Alan

Hi all,

A string of unusually good seeing here lately has allowed me to accumulate nearly 100 GB of data between imaging the moon, Jupiter, and Venus. 

The Jupiter image, still in b&w, is here:

http://www.mindspring.com/%7Eastro4565/jupiter20060717_203905.jpg

After trying several alignment areas and letting IIDC stack, I then decided to hand pick the frames, which made a big difference!  For this image, I hand picked the best 444 of 1800 frames @ 30 fps.  This is the red component (the color component should be along before too long I hope).  At the time I took this, it was still twilight here and Jupiter soon slips below my treelines now, so if I don't catch something before 9:30 or so, I've missed my chance.  I'm still having a hard time with the Mac's monitor settings, so I converted the .mov file to an .avi file and let Registax stack my hand picked frames.  Taken at F30 with DMK21AF04 and C9.25 SCT.  Jupiter was only about 35 deg altitude at the time of this image.  Gain at 885.  

I hope to be sharing additional Jupiter/ lunar images soon. 

Best,

Eric Todd
