Canon 600D, cls filter, Sigma 10-20 @10, F3.5 180x30secs.Stacked with Startrails.

I think if i had a darker sky this would have come out a lot better. I am pleased I got the hang of the Intervalometer. Bit of a palavar to do, change cr2 to Tiffs & then stack, time consuming

Very nice Fay.

Yes, it's a shame you can't stack RAWs in Startrails. The answer is to capture JPGs as it's not an issue with this sort of image.

BTW I think you have a couple of dodgy subs in there - there are some static stars! I had the same when I did one as I included a few test shots by mistook.

That's very nice Fay.  I'd echo Duncan's comments but it's a good start especially with new software and camera to get to grips with.

Fay

Thanks. how do you know that there are some duff subs  Duncan? not sure how I would spot them from the individual subs

Nice one BUT

You now admit the 600D is for astro use, which means the bad weather is your fault  :P

Very nice Fay, funny thing is I was planning on doing star trails this evening at the Outreach event, assuming there is clear enough sky.

Fay

No not really astro use Mick, i have been practising HDR photos & ND filters, normal pictures :lol: :lol:

Very Nice Fay
Good star trails and I really like the trees they make the picture, so I hope you will stop moaning about them now.  :cheesy:

Fay

 :lol: :lol: :lol: it is a palavar doing them. took ages to convert to tiff & then ages to stack them, we are talking hours here! i do need more hours and a darker sky. will set it up again at DSC

Agree looks really nice. Like Dunc says there are some static stars in your image so you probably accidently included a much shorter sub...?

If I was you I would just shoot in Jpeg & stack straight away without all the conversion palaver  (much quicker) & I don't think there is any benefit in shooting raw for this type of image (I don't think)...

Fay

yes i think you are right John regarding jpeg. Is it the big stars whose trail suddenly ends that are the problem?

Fay, if you look between the trails esp. to the left there are non-trailed stars from subs that are not part of the sequence. The blob at the end of each trail is probably a sub or two with longer exposures (hence bigger stars) taken at the beginning or end of the sequence - maybe you were checking exposures or something. I would look at leaving out the first 5 or ten subs as these are probably the culprits.

Duncan, all the subs are 30s F3.5. once i had it going i left it alone.

Just restacked in Starstax, a lot quicker, but then in Startrails I chose the longer option.  Duncan do you think that the Sigma 10-20 @ 10 could have caused what you are talking about, around the edge? It is nearly a fisheye.

Oh thats good, much much better than my naff goes at it.

Fay

thanks Chris. i would have liked longer trails & more of them but not that many stars were visible
