A rough night of imaging :(

I’ve been working with the Jupiter group a lot, and tonight yielded less impressive photos than the first two nights. We switched to the 55 mm lens for the sake of fitting Saturn’s rings completely in the frame later in the night. This cut the image size by about half for Jupiter, and changed the requirements for the levels. Because we have to use the lowest exposure time possible to freeze out turbulence, the images turned out darker than last night. The contrast is worse, fewer details are visible, theres some visible bias noise, and Registax is having a hard time aligning features. I don’t know whats going on, but hopefully my group (Saturn) will have better luck getting data.

UPDATE. Saturn showed up just about as clear as on the 105mm lens, but the seeing was noticeably worse. Registax will be the final judge of quality in that regard. No images from me tonight, the atmosphere has me in a bad mood. I need a hug and a comfy bed :(
