Ghost image.

Post by MAURITS »

When I use my 60 mm scope with a Lunt Ha 60 mm frontfilter than I see a nice image, but when I double stack it with a Lunt Ha frontfilter 50 mm than I see during the recording one double stack image.

From the moment I start the processing I see the image with a ghost image nearby.
What do I wrong or how can I solve that problem?

Hi Maurits

Unless I am misunderstanding, that is normal with externally mounted etalons Maurits, just tune the secondary etalon (the Lunt50) until the ghost is off the primary disk.

Thanks for the answer Mark, I have done this after tuning I don't have a ghost image during the recording, but I see it back during the postprocessing.
That's very strange ...

Try using the false colour option in Firecapture. It helps when you are tunning the two etalons
