Moon. Home San Diego, CA, LX200gps, 8", Philips ToUcam Pro 740k, prime focus, 130 frames taken and 34 frames used, aligned & stacked in Registax, final processing done in Photoshop 6; Levels, Gaussian Blur, and Sharpening. My first attempt using a webcam with the Steve Mogg adapter. I am very impressed with quality and relatively little effort to use this method of Astro Photography. I will try using my 6.3 focal reducer next time for greater FOV. |
