My first deep space image with a DSLR, mounted on the 10" SNT of the OLLR Observatory, here at Castle Yeti. The Orion Nebula:

wow,so how come this is your first?

Silly question, Is this as seen or has it been enhance colourwise? Whatever it's a great shot

20 second exposure @ ISO 400 Focal length 1016mm, aperture 10".
The 1100D was mounted in the telescope focuser via an EF-T-ring and 2" adapter.

It's my first attempt as I've only just got my mount anything like accurately polar aligned.

Other than a few tweeks in RGB the image is as taken, you won't see any colour visually without at least 16" aperture, but the long exposure captures enough light to show the emissions from the nebula.

Next trial will be to take several shorter exposures and stack those, which should eliminate any trailing of the stars, also I'll use the remote shooting via my laptop, rather than the liveview on the camera, as focus is probably the most important aspect.

A little post processing I think

Try 30 30 second exposures and download registax, used by us all in astro

In case you aren't sure of where to look;

I use Registax to process my avi files for planetary images.

I want to ensure that I'm not getting trailing, if 20 seconds is producing trails, 30 seconds will produce even longer ones. But as I refine the alignment etc. I'll be able to get finer detail and bring down the ISO if need be.

I'm going to get reading 'Make every photon count' again, as it will mean more to me as I am now actually doing the job....

Stunning images.

You've lost the cloudy bits....
