Collecting ASI-120MM-S (thanks to Ah Wah) and installing its CD driver as well as SharpCap. Able to achieve 59-60 fps when the camera is connectd to the Icore 5 - 3.2GHz 16G Ram computer's USB3.0 plug. Appear to be nice and easy to use. No hot/dead pixel observed yet upon quick check. Hope to try it...

I guess you may make an adapter to fit the 203mm ERF to the C9.25 There is no flatness data for the substrate material, that's why I called joiners are 白老鼠. The material is red glass, it must have extra layers of coating to reach the target transmission curve. With the 33-36% CO, a full aperture of...

Baader 1/10 lambda flatness with dielectric IR coating would be the 1st choice despite its higher price tag. Daystar and Lunt have smaller aperture ERFs but their flatness is only 1/4. However, the max aperture of Baader is only 180mm. I have enquired from Baader but they have no intention to produc...

C8 EdgeHD Ha (solar & DSO) scope released
Dear all, Be prepared to move up larger aperture to 8inch plus for Ha solar and DSO Ha imaging. Yes, dual purpose scope. A genius method to di-electrically coat the front corrector to achieve big ERF at 1/4 lambda. At present the biggest ERFs are 180mm by Baader D-ERF (1/10 lamda) and up to rarely m...
