Description

The data for this image was collected with a TOA 130 and ASI 1600 (about 32.5 hours) and a Planewave 12" CDk (about 32 hours). It is an L(Ha)R(Ha)GB composition. I felt this image deserved its own posting separate from my other IC-342 image as it is a wholly different scale--a different image really. Due to the difference in scale I registered all data to the Planewave red stack, and ended up binning the image 2x2 in software as the resolution was between .6 and .7 arcsec/pix, which is too high for my sky--though the planewave was used at a pretty dark sight. I was surprised to see that my data, was sharper than the planewave, though the planewave was cleaner. Therefore, I ended up rescaling my original image and blending it 50-50 with the new image. That seemed to impart the sharpness to an otherwise clean data set. I was also surprised to see that despite the ammount of data--no additional faint extensions of the galaxy were to be found--in fact I think I lost a bit. I guess galaxies to have an edge after all.

I would be interested in hearing opinions about this image compared to my original--can they be compared? If so, which is preferred. Its hard to argue with the scale--unless one prefers a bit of FOV. I find myself torn. In the end I decided that they can't be compared and decided to post it on its own.
