IC 405 and the FOV?

Recommended Posts

Ron Clarke

I imaged IC 405 (the Flaming Star nebula) and expected to see most of it in the finished image. I was using the ED80 with my Starlight Xpress CCD and a 0.8 reducer/Flattener as well!! I did about 35 x 300 sec subs + Bias and Darks.

I was shocked to see just a small portion of the top of the nebula and that was all that was in the FOV.

I will try this target again ASAP with my DSLR and see the difference?

Comments please?

Thanks

Ron

You do have the whole of IC 405 in the top image Ron.

It is the lighter greyish bit in the center of your image.

I would guess you need to back off the red channel when you process the image as the new chip seems to be very sensitive to the IR end of the spectrum.

Maybe an IR filter would help.

Thanks Graham, I do have an IR cut filter but haven't used it yet. Got a Moon and glow filter in at the moment so I'll swap them around!

 

Cheers

Ron
