November 16th H-alpha disk

Post by highqe »

Several weather fronts passing through the Sydney region, hence the seeing was very average,
that said, we had a clear window late morning.

Very nice FD image, Peter!

Is this "single" image for disk and prominences or this is combined disk and prominences different images?

Thanks for the feedback.

It's a single exposure, but I run my PGR 6.0mp camera in 16bit, gamma off.

PGR's internal gamma look-up-table is not good.

It causes posterization /banding in low contrast areas, hence I'm effectively shooting in RAW and stretching the data later.

The downside to 16bit is the camera can barely deliver just 6 frames per second....limiting capture runs to about 250-300 frames.

That's an excellent FD. I am not able to get that kind of details from a DMK camera.
