Subject: Jupiter through my 6" refractor

Reply-To: <alan@greatarrow.com>


Here is an image taken through my 6" A-P refractor using a Baader FFC to yield a 

focal length of about 3.5 meters.

I probably could have used a little more power. Seeing was quite good - Jupiter 

was just under 34 degrees in elevation.


These images were stacked and aligned in Astro IIDC using manual alignment. I 

used multiple alignment points and averaged the results - it made little or no 

difference at this focal length, the alignment done on the center of the disk worked 

very well. Processing was done in Adobe Photoshop CS2. 


Phil - the way to avoid the crispy planet edge is to use PS or similar program which 

allows you to select just the areas you want to process. This is the most powerful 

feature of this program.


best wishes -
