Horsehead (up close)

Well, my focal length doesn't really lend its self well to this object, but after taking a quick snap on my way to other objects I got hooked.

I had a lot of troubles that night and last night with dark pixels in my reduced images. Not sure what's going on there. The dark frames seem reasonable but something is amiss. It took a lot of processing to get rid of them, and get rid of a verticle line of shading down the left, presumably an artifact of the nearby bright star.

Even without those problems the image would be somewhat soft, being at 0.86 arc seconds per pixel. But you work with what you have

100% size, and only a couple of pixels cropped.

Consdiering all, I'm quite happy with the result, and won't be going back to it for a nother few years I expect (last shot of it with the ST7/LX200 was several years back I think).

Here too, although not any larger:

Good one Roger, there's just something about a close up horsey

Are those Alnitak rays crossing the image?

I hadn't imaged it since Dec 05 either until I did it a few weeks ago, musn't leave it so long next time.

Mike

I think they must be. They are always there the same in every shot. They are also in my shots taken in January 2006, so must just be an artifact of Alnitak and my telescope, they're not in other people's shots

Thanks!

FL was about 2187mm (+/- 10mm). It's a 100% view not cropped more than a couple of pixels.
