Description

The Orion nebulae (plural), using my wider field piggy-back setup, with Pentax 200 mm f/4.0, riding on the back of my scope. Focal length is over-rated for astrophotography. I like a nice wide-field. This one came pretty well, considering that it is a set of 45 by 60 sec unguided frames.
