Lagoon Tonight. I'm a happy camper.

Loving this it tell ya!

This one took me hours to set-up, photograph and process, but I am extremely happy with my little ED80 and Canon 400 D set-up.

Lagoon Nebula 17 minutes at F/7.5 ISO800 Darks and offsets removed blah blah. Processed with Deep sky stacker.

Manually tracked using an illuminated reticule on fork mounted C11 (polar aligned on an equatorial wedge)with the camera on the ED80, piggybacking on top.

Baz.

Hi,
Is this a single 17 minutes exposure?? It's really look good!!

Anyway, your sky must be very dark to get a single 17 minutes exposure without sky glow shown!! Nothing can beat a good dark sky!!

Happy imaging and have a nice day.

really nice shot.
I dont think it's a single 17mins exposure though, i'm pretty sure it's from a couple sub-exposures.

Nice image, Barry! I like the colours better than the usual all-red ones...

You are correct, the total exposure is 17 minutes. Each guided shot was around 171 seconds.
