First Astro Pics - Blue Moon Stereogram

[Arcturus]

So, here's my first attempt at photographing the Moon. I took two different pictures and positioned them so that it creates a stereogram.

To view the stereogram simply cross your eyes whilst looking at the picture until a third moon forms in the middle of the two. Most of you probably already know how to do this.

Why there is a gaping black hole in the centre, I don't know. Perhaps something to do with the focus on the camera?

That certainly doesn't look like focus. It looks like a damaged sensor. Have you been playing with lasers? :lol:

[Arcturus]

No, It isn't sensor damage.

When I took the picture the focus on the camera wasn't set at infinity. I manually focused it at the eyepiece. I reckon the black blob is actually the secondary mirror inside the scope. :shrug:

How incredibly cool (forgetting the hole of uncertain origin). It works quite well with the stereo vision. Apart from the hole the image is quite sharp.

Did you move the position of the mounting between the two images? If so how far?

Thanks for showing us all.

The mount wasn't moved. All it took was a couple of pictures taken a few minutes apart whilst the scope tracked the Moon. :)

How did you take the photo? Afocally with the newt and a camera pointing into the eyepiece?

If so, you're right - the black hole is actually the secondary. It can be a problem with afocal newt photography. Try various combinations of eyepieces and lenses (depending on teh camera). Even the positioning of the camera when pointing in the eyepiece can sometimes reduce/eliminate it.

Nice job.

[Arcturus]

Yeah, I did it afocally. Thanks for the advice Mike.

Glad to know that it was just the secondary. :)
