Orion The Hunter

I picked up a Hutech-modified 20D from Klaus Priebe and took it out for a test Friday night--by luck I had a dark clear night the day I got some new gear! Overall, I like the improved red response but miss the focus feature on the 20Da. I will mess with both cameras for a while, but I think that I will end up either having my 20Da modified, or I will buy a modded 20Da. We shall see. Clearly, the modded 20D cannot be used very effectively for daylight photography, whereas the 20Da can be used for daylight photography--decisions, decisions.

This is a stack of 6 10-minute exposures at f/4 with a Canon 35mm f/1.4L lens--you need to stop it down to eliminate the CA around the stars--at ISO 800. No dark subtraction; at 32F it was not needed. Images were aligned and stacked in Registar and all post-processing was then completed in PS CS2.

Lots of cool stuff going on this image. You can even faintly see the Witchhead Nebula--appropriate for this time of year!

Looks like the camera will do some nice work Jeff. I'd like to see how it performs at longer FL's. Good job.

That's a really nice widefield Jeff. I think you bought a winner there.

With most modded cameras there is a filter you can buy that corrects for the mod for daylight shots.

Let's see from memory its a X-nite CC1 filter. Comes in different sizes to screw on the front of the camera lens.

A modded 20Da with one of these filters may be the ultimate modded DSLR. I would go for the anti-reflection coated clear optical flat glass in front of the sensor. That's what I put on my Nikon D70 and the autofocus still works.

Best,

Greg.
