Is my DSLR sensor borked?

[ScouseSpaceCadet]

Hi, I'm still very much in the dslr orientation phase after picking up a Canon 450D a couple of weeks ago.

I've used it three times now for astro. Two disastrous sessions and the last one almost there... See below:

Clicking in the image then zooming in and looking at the dark lower left limb, there are a couple of coloured pixels in the frame right on the moon. I think one is blue and one is green (might be red - colour blind...🙄)

Is this a problem or some other anomaly due to the camera and if so is there a way around it or a fix? Thanks in advance.

I'm no genius by any means but I think you can't edit out those 2 pixels. What seeings are you using on your dslr, eg white balance, the image below is slightly over exposed so lowering the iso will help with that.

I think this is the sort of thing that using Dark frame images should allow you to manage in post processing. 

ETA  -  a quick google for Canon 450d Hot Pixel fix came up with this page - I have no idea whether it will work for you, but it's worth a try

Thanks for the replies. The 450D was attached to the Starwave 102ED. 38x4 sec exposures at 4 sec intervals. Shutter speed 1/2000 and iso 800. White balance at default.

I will take a couple of darks next time Gfamily. Ta.

Its quite normal to have dead/stuck pixels even on a new camera and the method linked too by Gfamily works for me..

Here is a video.

A couple of overactive pixels is nothing to worry about... singe pixel NR will get rid of them....
