Echoed - an amazing piece of work! Mind sharing your technique for taking and then blending multiple images? It's something that I would like to try...

ooo +1 for that
I regularly see people saying 'stacked images' etc no idea how you go about it though
Does Microsoft ICE work with dark images?I regularly see people saying 'stacked images' etc no idea how you go about it though

[quote=Gilhooligan]Managed to get my first relatively decent (for me with my kit lens anyway) night shot whilst up on the west coast of Scotland. Theres so little light pollution up there.
Mmmm milky way,Id be very interested in where these were taken in scotland. (how far north)?
And camera settings if possible.
Getting married there next month at a well known castle so i have a pic in mind.
Nowt wrong with kit lens mate, decent pics!!

Not too far, but quite far west. I was staying at cairnbaan on the kintyre peninsula. Camera settings were 20s exposure, f3.5 and ISO 6400. Mmmm milky way,Id be very interested in where these were taken in scotland. (how far north)?

Ill be staying near skye so prob about same way west, just a bit further north.Cheers for camera info, if i get the pics im after (trails and stars) ill post em on here.
Orange glow from sodiums can be a real pain....
Here is the advantage of using an Astronomic EOS clip filter [cls]...camera lens was left in manually focused /zoom positions from previous star shot attempts...they were probably moved as well along with some cropping to reduce image size for uploading but it doesn't detract from what the filter can achieve...both pictures taken on same night, from inside as it was bloody cold...
No filter in an extreme light pollution environment
With cls clip filter
Some Canons cannot physically fit the clip filter, your settings are totally awry from normal use but even with my old [now] 1000d's ISO limitations it's still able to remove the sodium emission wavelengths and give you something useful....
Edited to clear up different zoom/settings..

This thread was linked in another and it prompted me to both bump it and ask a question:
So anyone who frequents the P&V forum might have spotted I recently acquired a Samyang 14mm f/2.8, with part of my motivation for getting it residing in its astrophotography uses.
The other night I had my kit in my car and despite being within pissing distance of several towns and under 10 miles from Cambridge, it being overcast and me having no decent locations nearby I stopped to do a little experiment. We all know that you have to focus - to quote Bob's imaginary t-shirts
- 'to infinity and back a bit'. I wanted to see exactly what difference it made and I was a little shocked; there wasn't any. Here's a 200% crop:
The third shot which was a bit further back again was noticeably less sharp than the 'back a bit' image and so I had evidently gone too far.
Can someone knowledgeable on this subject please explain why we go 'back a bit'?
(P.S the difference in brightness of the images derives from clouds moving and light pollution hitting them)
(P.P.S the full (and rather average, hence being on Photobucket)image for reference. It was a quick edit and is too dark - I know:

Nobody knowledgeable has appeared so I'll have a go 
Is it not the case that many lenses actually go beyond infinity (Buzz style
) and when you go 'back a bit' you're going to actual infinity ?DibblyDobbler said:

Finally decided to get off my arse and star trail a well known Calderdale landmark, only for the cloud to start rolling in

A bit of a work in progress but it's given me a few ideas having a go on the next clear night.

Here's a selection of mine:

Folly by -robinecs-
Windmill by -robinecs-
viaduct by -robinecs-
As for stacking software I use a piece of freeware called starstax a lot quicker than doing a photoshop script.
