The sky cleared and the temperature dropped last night which gave me a few hours of viewing. I picked up Holmes 17P which is fading as the coma expands and got a few random shots while I waited for the rest of the eastern sky to move upwards into my field of view. I got some cluster shots before noticing Orion had slipped into the gap between my house and my neighbour which gave me a chance to image M42 in colour for the first time.

Tonight is clear again and I’m sooo glad I’ve got remote control working, it must be -4 centigrade out there and it’s been +14 all day. That takes some getting used to!

I left the camera while I completed a DVD quiz with the family and found nearly 500 frames of holmes when I finally got back to it. The result is interesting in that I think it shows some erratic movement in my mount, surely all the stars should show the same arc when I stack using the comet core as my target? Instead I have strange curves, take a look:

There not a lot of post processing gone into this, very little, so it’s a little rough around the edges.

I’m currently pointing the scope in the direction of the Perseus A galaxy which has several faint neighbours all within the SPC900NC’s tiny field of view.

I’ll come back to this post when I have more images, unless I freeze to the finder the next time I go out to realign everything.

I’ve just done a quick processing of this M1, my best yet but still room for improvement. The mount just won’t track for long periods I think it’s time I had the DEC axis apart for a regrease as well, or maybe I should leave it intact and adjust the grub screws, anyway that’s for another time. Here’s M1 taken from a stack of 28x40sec frames.

And another M42, this one is is taken from a stack of 200×2.5sec frames. When I get some time I’ll reprocess this with selective frames, but for now it’s just a rough draft.

There are more but I won’t have time to process them tonight so I’ll leave them for another day.
