first light with my nifty fifty

[Andywilliams]

There is so much wrong with this image that I am hesitant to share it but its an interesting and challenging learning curve!

I am very happy with my first capture of at least some of Barnards loop.

I was surprised at small the FOV was.

Im not sure whether the focus is soft or if it is coma?.....and I need to work on my tracking skills.

Barn door tracker. Canon 40D (modded). 50mm prime lens. ISO 800. 60X1min lights, 10X1 min darks. stacked in DSS and a quick process in photoshop.

all critique is very welcomed.

Yeah- it's upside down.......

Great image BTW- captured the Barnard Loop nicely

Nice shot! Looks like there's a stacking error?  All the stars are doubled up, kind of thing you see if you knock the tripod during a long exposure, are the individual sub's like that?

I suppose it is very hard to tell if you have pin sharp focus with a 50mm lens..... there is no such thing as a Bahtinov mask for a camera lens..... is there ???

You have spurred me into having a go at this feature.

I'm liking the scale and the star colours.  How did you prevent the bright stars in Orions belt from not over exposing and swamping the image ??

There is for a 135mm lens, I use the one from my Star71 - but that only gets you 95% of the way. Any tweaks after that are by eye.

Sure is, Starsharp2, not cheap but fits most filter holders, I have the 85mm one that fits my Cokin holder.

Thanks, wxsatuser.   I have now discovered something else to spend money on.

It's a wonderful hobby but wallets take a bashing.

Hi Craig, yes, all of the subs were slightly out.....my tracking issues I think. DSS was kind enough to stack them for me anyway and I am happy with the loop but 'must do better' with the pin point stars ?
