Alpha Centauri to Crux

[wayne anderson (Wayne)]

I went for shorter subs to reduce star trailing and hoped
that DSS would do the rest to round the stars out.

Stacked in DSS

I have a such question: how had you managed to take such a "linear" image without flats? Or with?

[Larryp (Laurie)]

Nice, Wayne!

Great photo Wayne. You really nailed the "Dark Doodad" in Musca and the "Coal Sack".

Does that camera have a Bulb setting?

Michael.

Thanks Mike, Laurie & Pupkin.

Mike, The camera does have a bulb mode but no socket or IR remote for a bulb.
If i use bulb mode i need to hold the shutter button down with a manual bulb.

Pupkin, This image of alpha centauri to crux is about a 70% crop of of the origional stacked image i cropped so much off to focus on the area i wanted to have in the image.

Nice picture Wayne , there are several options to control the Bulb function . I currently use a canon interval timer attached to an IR device that enables me to accurately take multiple exposures at any exposure length using my nex5.

Great shot Wayne. Great what you can do with just a tripod!
