Green moving object near Vega about midnight ??

[oldpink]

was trying to align the NEQ6 through some breaks in the cloud tonight
just before midnight Vaga was clear so I put the camera on to test the auto focuser
I ran a 10 sec preview and was surprised to see a green blob just off to the side of Vega
I ran 3 x 30 sec subs to see if I could get more detail, to my surprise I got a green trail moving across the screen

got some 5 sec subs as well that were dark but could still see it move out of frame

oops pictures seem to have loaded twice

Just an internal reflection of Vega, you have another 180deg from it but closer to the bright star. An object this bright really tests how well baffled the scope is and how effectiive anti-reflective coatings are.

Lens flare/Reflection.

.....strange the 'green' is not in the same position, it does look like its moved/moving?

The scope's tracking may not keep the star centred, so it's drifting slightly, which could mean that different parts of the scope's FoV is causing the reflected light to "move" around the FoV?

Or the focus point is changing (either through changes in the seeing or the focuser being moved). Certainly the "tightness" of the star seems different in each frame.

don't think its a reflection as its moving way too fast to be caused by tracking movement
there was a lot of high cloud causing variable viewing conditions, the whole sequence from the first pic till it moved out of the FOV was just under 3 minutes

I, too, think it's a reflection. You can see an associated blob bottom right of Vega, quite close. It also moves away from the star. It's an interesting effect though!

Had similar experience the other night http://stargazerslounge.com/topic/222887-the-blob/ but nobody found it worthy of comment 

A refection does seem to be the most "earthly" possibility

If it's green it's probably Klingon

You should ask Ogilvy the Astrnomer...he has good form at explaining and catagorising Green Flares...something about a million to one and being of no harm.....

On serious note it does strike me as a lens flare / reflection too. Could alse be amplified by a small finger smudge if there was one there on any optics in the chain (reducers, coma correctors, filters,
