First Light: Celestron NexImage
I haven't been crazy about the Meade LPI, so I thought I'd give the Celestron NexImage a try. First impressions--a bit noisier on Mars, but three times faster capture. I can also use equinoX to drive the camera, which is much easier than how I had been capturing with the LPI. Hardware is still the 10" LX200+Televue 2x Barlow+Televue 2.5x Powermate (12,500 mm efl, f/50). Processed 1000 frames in KIS, stacked best 400, multiple passes with small wavelets. Histogram & smart sharpen in PS CS2.
This image is sub-par, and it's my own fault. It was cloudy all afternoon, so I didn't plan on setting up. But when I went outside at about 9:30 and saw clear skies, I quickly set up on the driveway. The scope never had a chance to reach ambient--it came out of the 70° house into the 50° air. The image was bouncing all over the place. I just wanted to try out my new camera.
