Hi,

My four-day BAUT ban gave me ample time to learn how to do polar alignment properly and try out my new Canon 400D at the prime focus of my 8" SCT.

This is my first attempt at Omega Centauri.

50 x 30 seconds @ ISO1600. Dark subtraction, stacking and processing in IRIS. No flat field applied.

And here is my first attempt at M83 (my first ever galaxy!).

50 x 30 second @ ISO1600. Dark subtraction, stacking and processing in IRIS. No flat field applied.

Any criticism and suggestions for improvement would be gratefully received.

Clop,

Your shots are excellent. How did you link your Canon 400D to your scope??

What telescope are you using???

Hi hpkl,

Thanks. It's a Celestron Celestar 8 Deluxe. The image of Omega Centauri was taken with the 400D piggybacked onto the top of the telescope using the Celestron piggyback adaptor, and a 200mm telephoto lens on the camera. The image of the galaxy was with the 400D at the prime focus of the telescope, mounted using a Celestron Deluxe Tele-extender and a T-ring.
