Just getting back into star gazing after a long break always used a mates telescope but have just purchased and am setting up a Meade SC 8" on a pier mounted Super polaris with AutoStar system.
While checking alignment and drive speed I had mounted my SLR with 300mm f4 lens and snapped a couple of 30 second exposures of Jupiter and on review noticed a moving object in the frames.
Now this green mystery object appeared it was too slow to be a satelite or other normally fast moving things like a metiorite.
I have uploaded four images, two were about a minute and a half apart and the other about seven minutes away. The fourth is an enhanced crop of the object showing a halo around it like could possibly be seen around a commet or a large asteroid.
How do I go about identifying this mystery object??
It looks interesting so any help is appreciated.
Its most likely an internal reflection in your camera lens. A few people have posted images like this before, and that green colour is very typical of of this effect. Bright objects like the moon and Jupiter do this on a regular basis.
I agree with Jacquie. It is an internal reflection of the lens from a bright object. Just look at the symmetrical position of it: It is ALWAYS on the opposite side of the bright object same distance from the centre of the frame.
That thought did cross my mind but it was nice to think I'd found something even if it was just for a couple of days.
I have seen this before with terestrial pictures at night with bright lights in the frame and it was due to the daylight filter fitted for lens protection.
Removed the filter and it doesn't happen as the lens coating is good and doesn't reflect like that.
