DF I've never thought of focal length when using the AT65. I'll have to think about that or google it.
The 65 means it has a 65mm objective, that is all I know.
30 seconds was the longest I could go without tracking, anything beyond and I was
getting star movement, and ISO was 12,800.
Later on in the night I did use tracking and longer exposures for the Pleiades, Bodes and the Cigar galaxies
with exposures of 1-2 minutes and ISO 3200.
Haven't gotten to them yet in processing. I had to go back to work

I still dont get it, excuse my slow brain

When i shoot stars with a 16mm lens at 30s i still get starstreaks. How is this prevented at 65mm? With trackign i can understand but without?

Its a telescope is in not? Dont think the same rule applies. Could be wrong. There will still be a max duration but not sure what that is

I understand what you mean, given how "zoomed" in Andromeda is, a single 30 second exposure with no tracking would be a blurry mess. Must have been tracked!

To be honest, not interested at all. Whats the difference in shooting brackets and make an HDR in lightroom? It works fantastic and there you have at least both source files and not a baked-together raw file.
To me things like this is so prone to ghosting effects and other strange behaviors...

Oh, OK then...never mind.

Well I'm intrigued at least...want to have a look at it. Thanks for posting the link.

My main skepticism would be around the fact that the samples are super-easy to solve blends (ultra-flat seascapes with no towering trees, mountains, etc...

Beautiful.

Some very nice pictures on here lately!

Thanks Guys - I am really hoping for some camera time this weekend!! It's been so long since I've really thrown myself at it but it's not exactly the time of year for it either!

That's true Eddie. I just don't remember a lens correction on vignetting this severe in ACR. Here is a comparison. First, straight into ACR and then after lens correction is applied. I definetly like it better without the vignette correction so that's added an extra step for me.

Sorry Gene I can't help. I love this tyoe of lighting...

I can only imagine having to raise 3 boys... shooting them was trouble enough! This shot perfectly sums it up I think

Geez, I look bad enough as it is! This edit makes me look downright goulish.
