Images 5D Mod, Test Run,

Hi Everyone,

Well, I suppose some of you have been waiting for this, however the results are just a test run with the modded 5D, in very poor conditions, so I am really posting these to be ripped apart with many suggestions from anyone wishing to respond.

Last night was probably not the best night to try this, as the moon was high and bright, and conditions were pretty poor, but I wasn't trying to take nice images, but rather have a look at the performance of the modded 5D

Anyway, I took 7 exposures of the Cats Paw and Crab Neb, at only 2 minutes and 30 seconds each, @ 400 ISO, with INCR on, and made sure the cover was on the Angle Finder, no light leakage.

Also took 20 Bias frames at 8000th Sec, and this morning took 20 flats of the morning sky just before sunrise, nothing had been altered on the scope and camera, and it was as when i took the lights last night.

I processed all the required images in both DeepSky Stacker, and did the same with Image Plus for comparison, and what a difference there was.

The colour of the images surprised me a bit but realise now that with PS this can be fixed, how I do not quite know yet.

No. 1. image is the combined, aligned/stacked result, from DeepSky Stacker

No. 2. image is the combined, aligned/stacked result, from Image Plus.

No. 3, image is the combined, DeepSky Stacker image with Auto, Digital Development in Image Plus applied only

No. 4, image is the combined Image Plus image with Auto Digital Development in Image Plus applied only

No. 5. image is the DeepSky Stacker image adjusted a bit in Image Plus.

No. 6. image is the Image Plus image adjusted a bit in Image Plus.

I'm sure you can see a vast difference, and after being very careful with the image taking and the way the processing went, I still have that horrid central brightness in the Image Plus processing.

So what is causing this, maybe some one can come up with a suggestion.

It dose however make me think that there is some thing very wrong with the software.

Please look at the results, and please be cruel if necessary, and give me plenty of tips especially the 4th image, yuck

Thank You.

Leon
