yet another m42.....

Orion Nebula, 4" f/10 Mak; Canon 300d; 5min exposure; ISO400
I just tried to process this quickly now...will give it a proper go tomorrow when I'm fully awake

Thats a decent start Michael.

Now all you need to do is get about 20 of those and stack em

How did you guide the image?

I hope you dont mind me playing around with your image a bit. Heres what I came up with.



Images Plus, Levels, star tightening, very slight unsharp mask.

Dave,
Feel free to try and process any of my images.
That's a very interesting looking version you have there from Imagesplus. Certainly brings out the filaments in the nebula. Like you said, I need more of them!
As for guiding, I guided by hand. I placed the dsi in the LX90 and simply kept the star on the centre of the sceen for the length of the exposure. I didn't get it perfect though.

Michael if your gonna guide by hand like that heres a tip I used once before i had my autoguiding setup.

tape a sheet of transparency film over the screen draw a fine x in red ink on the transparency near the guidestar. now center the guidestar and keep it there for the exposures. Its pretty much what your doing but allows a bit more precision. Also slightly defocus the guidestar. This makes it easier to judge and also removes atmospherics from the equation a little bit.

Good suggestions Dave. Thanks!
What I did was I used the cursor as my crosshairs. However, it wasn't the easiest. Eventually, I'd like to have the whole auoguiding setup working automatically. All in good time though...
Thanks,

Also remember that when you get a load of these images small guiding errors will average out and wont be so noticable.
