m42 - 300D modified...

Here's a recent M42 from the SF bay area....

This was done with a camera I modified using a
8" f4 Meade Schmidt-Newt and guided w/ a DSI-Pro.

A IDAS-LPS was used to cut down on the sky glow.

A very nice image Jeff.

Very nice, Jeff! Stack/layer this with some shorter exposures to bring out the Trapezium stars, and you'll have a winner!

Lookin' good Jeff!

Great shot. There is some coma in the top left side. Is that because your camera was not square in the visual back? Sometimes visual backs have a bit of sloop in them and you have to push them hard up into the visual back before you lock them down. Also it is good to have screws on both sides or 3 sides of the visual back holding the camera in evenly so it is not leaning down out of square.

Also perhaps the collimation of your scope is out.

Sweet shot! 8)
Thank you!
