M45 as a Stereo Pair
Parallel Vision 
Cross Vision - -
I found this oldish image of Reflection Nebula M45 and turned it to Spatial format.
I have imaged this one at 2007 with SW 80ED scope.
2h with QHY8 and a IDAS-lp filter.

The good old Moon as a Stereo Pair
real stereo pair. There is two ways to do it. First you take two pictures from other sides of earth
at the same time and there will be some minor parallax.
Secondly the libration of the Moon can be used for that, you just have to wait a longish time to
have a same phase of the Moon but with differen libration amount.
In fact, several stereo Moon images has be done by this way.
-
In above image, there is same method used, as with my DS images, to
create a pseudo parallax between images.

I shot this Full Moon image at 2005, more moon images from me can be seen here:
IC1805 core as a Stereo Pair.
This complex formation is located in a core of IC1805, the "Heart Nebula".
I shot the original 2D-image at January 2008.
Image can be seen in this post:

Wider view shows the whole nebulosity complex.
This object can be seen in a Right at very center of the Heart shaped Nebula.

Sh2-223, 224 and 225
In HST-palette

This was the moust difficult target.
The image spans about five degrees horizontaly, there is two
old Supernova remnants in the same field of view!
Extremely low surfage brightness and large angular size makes
this trio from the Sharpless catalog a very challenging to shoot.
There is a very dense Star field. Note. the "noise" in the image is
not a noise but Stars!
I think, this is more difficult than a SH2-240.
It can be seen in my older post, here:
-
I spend three nights for H-alpha and here is the result.
I think, this must be the firs NB color composition from this target?
Least I wasn't able to find any.
-
Total exposure time for H-alpha channe is 11h.
Taken with very fast optical configuration @ f1.8.
