What is this Blue Object??????

[atalas]

Interesting , every time you put your camera in your scope and take an image would the camera be in the exact orientation every time ? Its starting to look more like Its an internal reflection ,would explain the movent If the camera wasn't in the same position for every shot . Also as the star moves lower down, the angle the star light hits the camera might change the position of a reflection in the camera .

I think this focus shot was taken 2 night ago.

I loaded your image and stretched the levels, cropped the strange object and did a 3x enlargement on it to get the two images I attached.

Well it certainly doesn't appear to be an astronomical object.

is it a doughnut?

yes i thought that too! However, I have a Canon 300D and when I see doughnuts on it, they never look anything like that!

The enlargement seems to show concentric rings !! And the bright spot at centre almost looks like a secondary mirror (a tad out of collimation) !! ??

Interesting Paul....

I just wish I could have some clear sky to take some more images....

Even off other bright stars.

Looks like my moving planetry is not looking any good anymore.....lol

Tony, before you posted those images did you crop them at all. If so can you upload the uncropped images. I'd like to see where your "blue planetary" is situated spacially on the chip in each exposure.

Also can you post your exact times for when you took the shots eg 8:30 PM 25/10/05. You can get that info if you right click on the original image in windows explorer,
select properties,
then the summary tab,
then advanced at the bottom right of the properties box.

If you then scroll to the bottom of the images list, Date and Time Taken will show up before the description section. This will be helpful, assuming your camera has the right date and time set

Oh and if your home now check your camera time against the time at the bottom of the page here. Just to check

[Striker (Tony)]

Paul,

The second uncropped image I posted was 22nd October 2005 9:53pm

This one.

I have checked the date & time...its correct...but it could be a minute or 2 out at the most.

All other pictures have been edited so no time or date available.

You don't keep your originals uneditted and save the modified ones as different images

Are the others uncropped and at the same focal length/magnification?

[Striker (Tony)]

Yes I do Paul...but at the time these were just focus images...nothing special....

The others would be the same focal length but they could have been different rezolution as I was playing around with DSLR focus image quality settings.

I might have more originals on my observatory computer.

It's a fake. Well done. You had us all going there for a while, Tony!

[[1ponders] (Paul)]

If you wouldn't mind would you zip up the originals (jpeg would be fine as long as they haven't been cropped) and email them to me at my yahoo address. I'd like to have a close look at them and have a bit of a play with them. They were all taken at prime focus with your celestron and a Focal reducer, right?

Tony, if you can capture again, swinging the OTAso the star moves to a different point in the FOV should prove if it's a reflection. If the blue Unidentified Object stays put, relative to the star, then it's can't be an internal reflection....
