When I shot the North American Nebula, my astro-buddies said things like “Wow your unmodded Xsi picks up a lot of red” and I thought, hey, maybe I can hold off on an expensive and intrusive mod to my precious Canon.  All of those thoughts disappeared as I began to process my photo of NGC 1499 yesterday.

This nebula doesn’t even EXIST with an unmodded dslr!  I suppose the photo above shows a pleasant mix of coloured stars and faint pink nebulosity, but if you’ve ever seen a REAL photo of the California Nebula, you will understand my predicament;)  So here’s the plan:  Since I do not want to rip apart my 450D just yet, as I use it A LOT for daytime photography, I will wait until boxing day, at which point I will buy a new dslr, then either mod the 450D myself, or fork out the cash to do it right at KW Telescope.

I decided I would give this object a fair kick in the can.  I added about 2 hours of data under dark skies at the CCCA.  It was a nightmare to process however.  Because I stretched it to its limits, I revealed light pollution, amp glow, gradients… you name it!  I don’t usually like to stretch images this far.  Needless to say, I won’t be imaging the California Neb until I modify my 450d!

  1. Before you go down the modded route, try a 7 or 8 minute exposure at the observatory.

    For sure I will. I want to push my exposures to the limit.. but it would have to be under dark skies at the CCCA!
