Description

This was my first test of a new Hyperstar lens for an EdgeHD 1100.

The color data were taken one night with an ASI1600MM-Cool attached to a ZWO-EFWMini. A new spacer for the EFW must be obtained to get proper spacing with the filter wheel. The back spacing was off by 9mm and there is a lot of distortion in the color data. The color data were combined and Gaussian blurred. The Red and Ha channels were blended at 70%/30%, respectively. The luminance data were taken with the proper spacing restored and a 1.25" CLS filter threaded into the ZWO T2 ring adapter between the camera and the Hyperstar lens.

For version 2, I tried adding the H-alpha to the red channel (1:1) and 30% of H-alpha to the blue channel to simulate H-beta.
