Anyone know how to trouble shoot the above problem?

attached is a pict of Trffid Neb. 38-30sec stacked exposures at 800iso. the image was stretched, resized, aligned,etc.

Any hints would be helpful
THanks

RAW image transfer into the computer using a Canon 10D takes about 30 seconds. This is the same amount of time I usually allow the chip to cool between images.
Does the chip remain active? Which would mean an additional 30 second buffer; or, am I good to go once the image download is complete?

Thanks.

Sorry for double posting,
This thread was initially started in the 'Equipment' forum without a reply. I am hoping for better luck here.

Photographed on 8/9/04 with a Canon 10D and a Barn Door Tracker. It's a single 30sec,f/5.6,28mm,iso400 exposure.
Enjoy!

I am not sure where to post this since it is not a CCD or film image.
While imaging with a Meade LX200 and the Canon 10D I experience REALLY bad vignetting. In this example of M51, without dark-frame subtraction, only 8 (of 45) - 1 minute frames have been stacked. I have already subtracted a radial gradient in PhotoShop and am left with what I call the "doughnut nebula" . The images where taken at 800iso. The effect shows up almost immediately once one- or two frames are stacked.

If anyone has experience imaging with the LX200 and 10D and has any suggestions as how to reduce/eliminate this effect within the setup; it would be appreciated. I am supposing I would either need to move the camera closer or futher.

Thanks in advance.

Nico,
Geat shot and nicely framed with the architecture. I am assuming your 'D10' is the Canon 10D. I got mine about a year ago and have taken about 2500 picts so far(but who is counting).

Attached is my very first-ever attempt at astrophotography...It's M57(Ring Neb.)9-1min exposures @ 1600iso with a Meade 8in SCT.

Great site!

Holy Crap! 8O
