That's good to know Bill. As you know, I modified my handset cable so I could tweak settings remotely from indoors, but for those that choose not to, storing the handset inside the housing could be a pain. So its nice to know that once the camera is set, the handset could be removed and all the settings remain.
After the moon passed behind the house and the cameras were in shadow, even with this slight increase in contrast the mag limit dropped to +5.2. Caught several meteors but none bright enough to generate a spectrum. (Did actually get a bright one on another camera, typical.) That itself is a significant change, don't normally get any "normal" meteors with the other gratings on the 902's Nonetheless I hoping that the 910 combined with the high quality substrate will raise the detection limit a couple of magnitudes. That should improve numbers. Time will tell.
It's an assortment of odds and sods I've accumulated. I generally use 300 grooves/mm or 600 g/mm. 25mm and 50mm square. The 50mm square ones fit nicely into 72mm rotating mounts making them east to attach to the lens. The 600g/mm seem to give the best results from what I've captured so far.
Hi, I monitor a couple of weather sites but I'd never seen that one. Looks like good astro info.
It turned out to be a very good night, with a nice bright meteor 0058UT. Got it on two cameras. Had a quick look before heading to work. The spectrum has very bright sodium emission with a trail. I'll process it fully tonight.
