Orion's Belt & Sword: great mosaic in H-alpha

Post by Danilo Pivato »

Hi all,

a photomosaic consisting in 17 shots that show the central
part of the constellation of Orion.

The mosaic measures approximately: 9°x8° (6464x5860 pixels)
and was completed in 21 nights.

The total time exposure of all frames is 76.5 hours

The equipment is Telephoto Nikkor 300mm f/2,8 @ f/4;
CCD: SBIG ST-10XME with H-alpha filter.

The location is my balcony observatory in Rome:

It is a wonderful photo.
There are two questions I have.
I see no diffraction spikes around bright stars at f/4. I presume the Nikon lens has either 9 iris blades or shaped iris blades to give a circular aperture.
Also the off centre images of the brighter stars in various locations is presumably a result of the mosaic nature of the photo.
In a single photo the off centre bright stars would congregate at the edges.

The detail and contrast and extent of the photo is wonderful.

Regards, David
