I had a quick imaging run last night after spending some time re-establishing my polar alignment. Decided to try some longer (4 min) subs with the ED80.

Here's 15x4 min with the DSI II pro/ED80 combination from Brissie.

Nice. There is plenty of potential in that for a colour shot. I must try with my Zenithstar sometime...

The seeing was good last night. I tried a little myself, but nothing worth going public!

Thanks Jonathan. I forgot you had that ZS. You'll get a nice wide field with the ZS and the DSI III. If you get some good colour we should get Allan to do the registar treatment.

4 min subs now? I told ya! :) Good results. Easier to process with those longer subs?

Thanks Rob and Frank. The conditions here were quite good on Thursday night although there was a bit of smoke about from a fire. I'm thinking the image is probably a bit under-sampled (3.6 arcsec/pixel) with this combination.

Troy, the 4 min subs meant I did a lot less stretching than I would with 1 min however the galaxy core is over exposed so to get a really good image I'd end up having to layer some shorter subs into this image.

Very nice image Peter, Needs that bit more focal length.

A bit of colour data will finish this shot off very well.

Thanks Doug. I was having a read of Robert Reeves book on webcam astrphotography. If I understand what he's saying it looks like somewhere around 1.4 arcseconds per pixel is where I really need to be.

I was planning to get some RGB data (if the clouds go away) and try my first LRGB.

Nicely done - now lets see the LRGB version
