First Startrail

[Fay]

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

[The Thing]

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

[mickw]

Nice one BUT

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

[Carole]

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

[julian]

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. 

[Fay]

  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

[JohnP]

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? 

[The Thing]

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.

[Fay]

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.

[Rocket Pooch]

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
