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.

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:

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
