Eta Carina taken by myself, Charlie B and Dave S on 3 May 2008, it is a 5 min exposure at 1600iso taken with a Canon 350D Unmod using and Orion 2" Deep Sky Filter. At Prime focus with a 102mm F/5 Skywatcher piggybacked on my trusty 10" LX200gps. (Autoguided with a DSI)
Brightness and contrast adjusted in Photoshop, NoiseWare was used.
This is one object I cannot tire looking at, everytime you sneak a peek you always see something you've missed.
Amazing effort from the unmodded 350D. Hoping to try this soon too with my achromat.
By the way - you have a nice refractor there. Wonder if the williams optics field flattener would have a good effect with your scope (if it can be fitted).
Thanks to all who have responded.
The scope works well with the setup, I have a Saxon ED80 which works really well and am more than happy with, but this Skywatcher 102mm I'm certainly suprised as well.
At first, imaging (attempting anyway) the horsehead, the CA was more noticeable because of Zeta Orionis, the brightness of this star after 10 minutes exposure compounded the CA problem but is hardly noticable imaging objects around the fainter stars, I have to admit the filter I use fixes alot of these problems. (As cheap as it is...it works!)
I will have to look up the Williams Field Flatterner and see what thats about because in the corners of the image there does appear to be slight trailing.
