Lagoon and triffid widefield

I forgot to charge my battery, so had to dust off the DSLR (I was not going to waste a perfectly good alignment).

Funnily enough, there are still some stretched stars in the corners despite the use of a dedicated flattener on the FS60.

Also, there are some artifacts in the lagoon - not sure where they came from, everything is clean and I used flats (my new lightbox from exfso), so would appreciate any ideas how they might have shown up.

The attached JPEG was compressed to 30% quality of an 85% reduction of the original. Levels were adjusted in GIMP and no other processing was performed. It is the best 120 of 150 x 30 sec shots with 50 darks, 50 flats and 50 dark flats taken with an unmodded 1000D on an unguided mount at 370mm FL.

Hi Matt

That's an excellent shot of this pair, very well processed by the looks of it but I am unsure of the artifacts you are refering too..?

This version cannot really be appreciated with the terrible jpeg compression artifacts though.

Mike

I would like to thank Mike for hosting my image . I should look at getting a wordpress or similar account - that makes 2 images I am (reasonably) happy with now

I must say I was pretty surprised at what 30 second shots could produce - I only got the DSLR out because I had no power for my CCD. I will have to experiment with that a bit more...

The blotches in the bottom two-thirds of M8 I am a little concerned about - I have not seen those in other pictures. Maybe I need to hose out the Canon? The rest of the optics are virtually pristine ...

A really lovely image of this lovely pair Matt. The hi res image is superb. The overall field of view really adds to the image beautifully.

Well done.
