I used SharpCap last night to get color images of M33. I took flats and darks at 2 minute exposure. I set the camera mode to 16-bit for the first time, which selects 14-bit mode. The captures I find this morning are all monochrome, not color. There is also a tiny grid pattern on the low-level details in the photo.
I am testing this by capturing terrestrial images today with SharpCap with no flats or darks and they are in color on the screen, but when I take a "snapshot" and look at the PNG or TIF file, it's monochrome and has the grid pattern in the lighter areas. I think I have tried all of the settings on the right hand side and nothing changes it to color.
I recently did a sensor analysis for this camera. Could it be that went awry somehow?
Prior to doing the sensor analysis, I was getting color images using 10-bit mode.
Also, when I take flats, it asks whether I want a monochrome flat frame. Should this be checked for a color camera?
Also asks "capture and subtract bias frames" - should I check this one?
