Greg.

Thanks Greg. This is a broadband Astronomik 2" 740nm but I'm getting some 1.25" from Edmunds.

Thanks guys. Different take on known objects. Good for moon nights too.

I suspect there is off band leakage (eg UV) that causes star bloat with some filters.

You might want to try a UV cut in the image train as well

Thanks Peter. You are absolutely right about the UV leakage. I normally use a UV and IR cut to narrow the bandwidth but need to work out where to chain the filters in the imaging train with the new scope. With other scopes I used GSO tube extensions and they have threaded end which are convenient to add filters.

Thanks Mike. Yeah, anything that allows me to image under my bright orange skies.
