Hi Guys,

I attended the SPSP but only managed one photo.

(1) Polar Align, 3 star align normal manner
(2) Slew to Eta Carinae, can see Eta in eyepiece
(4) Remove eyepiece, add camera, focus (takes me 40 minutes)
(5) Take a 5 minute sub and got this result

Its a starfield but no Eta. I cant have knocked the scope coz its a 5 minute sub and the tracking looks OK, it was subpixel. I slewed away then GOTO back to Eta and same result. What have I taken a photo of? What happened?

I was very dissapointed and after showing my daughter some lovely scopes (thanks Rod) went to bed. This was my first time under dark skies and I would have loved a shot of a nebula.

I just used my normal procedure and this has never happened before?

Any thoughts appreciated.

Paul

Just one of those things Paul.
Tomorrow is another day.

That's a puzzle, Paul. There's no nebulae in the photo, and it looks deep enough that there should be if you were close to eta. I've had a bit of a browse through CdC but I can't pick the starfield...

No idea, but even a 5 second sub will show you the object, so 5 minutes will have a ripper. Bumped it perhaps? Could you see Eta while focusing?
Like Doug said "it happens", actually Forrest said that too.

Nice detective work there, Houghy! I was looking too close, I think...

Houghy,

You are absolutely brilliant :). Thanks so much. It is close to Eta so maybe the mount wasnt locked down enough and I changed the alignment while putting in the camera.

Thanks everyone for helping.

You live and learn.

Just for fun I have processed it, amazing what one five minute frame from a dark sky site can be like. Coz of the number of stars, saved at 30%, 900px.

On the upside: this is a rare and good image of the dark nebula FeSt1-157 - I guess not many people have tried that before... :)

I didnt get there till Saturday evening and set up at the imaging field across from Mike. I had a look for a giant scope on an EQ6 but couldnt see one :)





Next time maybe i should setup and then just spin the EQ head and see what I get :)
