Mitch,

Only the Ha image is showing in your post. I don't know what happened to OIII.

This is a good quality light frame. How many do you have? It's too bad you don't have darks. This is definitely stackable.

Next time take 15 darks before the lights and 15 darks after the lights. You will then have a total of 30 darks that you will use to create one master dark. I think you will be very pleased with the results.

For now I would not worry about taking images with all three narrowband filters. Build knowledge with Ha and then move onto the others. I've gotten good at Ha, next step is OIII when the weather clears. Several weeks ago I used an exposure calculator at Starizona. (Actually I had to modify it for use with CMOS cameras.) It told me that I needed a 200-second exposure for Ha and 90 seconds for OIII.

Gents

Don't worry about the 'attachment is missing', this issue is under active investigation with Robin and myself.

Mitch,

Dave and I have had a lengthy conversation with cuivenion on the topic of Offset.

viewtopic.php?f=9&t=1209

Silly question: Have you dialed in enough Offset in your images? Offset 0 is evil.

Try and keep up ...

I have put some serious stuff in the other thread.

It shows through in your problem solving and analysis technique.
