Jarrod, thanks for the pic's all looking excellent what is another good point is that you are describing how these pic's was taken which as a guideline will help others and give me hope.

No worries, the pictures aren't much but they at least show what sort of tracking I can get out of it.

I just try to explain it as I go not only for others but if I'm doing something wrong then hopefully someone can advise otherwise.

Here is a slightly better version of the last pic I posted, I'm still trying to get my head around gradient removal but I think I'm starting to get the hang of processing.

As you'd expect, we're always on the lookout for stuff shot using the Polarie.

If you have a few minutes (4 and a bit in fact), this video was compiled using time lapse images taken with the Polarie:

And this seemed to me to be a pretty good solar image taken by Tom Kerss:

There are many ways to do it - Google for "time lapse stacking" for various tutorials. I've seen stuff on how to use Adobe Lightroom, GIMP and others. There's probably info somewhere here on SGL too.

I know that Quicktime Pro is one pretty straightforward method - you select File... Open Image Sequence and select your images and a frame rate. Provided the images are sequentially numbered, QT will do the work and then you can save a movie format.

HTH

Cheers, Pete

There are an awful lot of blue halos on the stars. What were you using?

Did you have IR/UV Cut filters somewhere in the train?

Cheers

Am I the only one who read the title of this thread and thought: "Ooh hello! I'm Julian and this is my friend Sandy!"?

Hmmm. I did think: "What brings you trolling in here", but... :p

Maybe widefield VIDEO Astronomy, for those less patient? Have been dying to try out some of my old Dad's manual SLR Lenses. Those nifty little (fast) video-cam lenses give Real-time views to mag +8 seemingly? A bare lens and a tiny videocam makes (dragging out) an HEQ5 seem slight overkill too. ;)

For some reason I didn't get the alerts that people where posting here again, sorry about that folks.

No filters or anything, it was using a cheapo 70-300mm lens and it was the first time I had used that lens in that fashion so it was more of an experimental shot.

What I think/hope is the main cause is just that the lens wasn't stopped down so I'd try it stopped down next time and then again with a LP filter. But to be honest I haven't really seen many good things said about that lens in the first place, so how much of a difference it'd make I don't know.
