Description

This is a first light image with my new ASI6200MM that was intended more as a test, but evolved into a new project. I started this project with a QHY16200A on the same scope, and wanted more data with this, but in the end liked the wider field so much more that I went with this data. This is all taken in one night, and due to poor planning on my part (I didn't expect the data to be that clean), I only have 3 Ha and 4 SII exposures. The OIII in this region is pretty faint, so that's why I concentrated on that to get the noise down. I still have some spacing issues to resolve, which should be done when my new adapter comes in. In comparing the OIII channel from this camera, and the QHY16200A, it was a night and day difference.

It seems gain=100 will be a good test to do as well. Early indications show a lot of improvement at gain=100 vs. gain=0 for narrowband with only a minor impact on dynamic range. This was taken with Gain=0, Offset=0, but I had previously built my bias/dark library with offset=50. I had to get creative with the dark subtraction, but honestly this sensor is so clean I probably didn't have to do that.
