Description

I decided to image this object as a test following an equipment reconfiguration. I replaced the field flattener on my Tak TSA120 with the focal reducer as I was never quite happy with the performance of the reducer. The focal reducer introduces a .7x multiplier resulting in a FL of 5.25. I don't think that I have quite nailed the reducer to camera spacing just yet though I think that it is close enough for now. We can only fiddle with these things so much.

The image data was captured in sets of 90 second subs as I wanted to avoid saturated stars with the QSI 683 camera. It also allowed me to capture all of the LRGB data that I needed in a single night session. The image published here is a 60% crop of the source frame size.
