Mike Where did you get the Rainbow fisheye F1.4/1.6-3.4mm c-mount lens you show in a previous post? I have searched ebay and the internet and cannot find it. I am very interested to get it. I am using the stock lens now for my allsky camera. I would like the superior resolution of the rainbow lens. I am using this camera as an external sky camera for my remote observatory. My observatory is 100km west of my house over a large ridge. THe sky conditions there are often very different then at my house. I cannot determine the sky conditions until I open my dome and even then I'm never sure. The allsky camera will help me tremendously. I greatly appreciate any help you con offer.

Bob, the model number is L163VCS. I paid $70.00 on eBay for mine but I've seen them as high as $200 on other sites. Do a search for Rainbow L163VCS and you'll get results. The difference between this lens and the stock lens is night and day.

Hi Mike, were did you source the clear dome I have searched for clear acrylic 80mm half spheres on the net but can not come up with any thing that looks like yours with a lip on it. Also could you explain your resister heaters parts and how you wired it, that's a great idea.

I know this is way off the subject of refractors but where else can I post? Banned from CN of course. I like this forum much better anyway. It has a minimum amount of drama. If this "All Sky Camming" continues to amuse me I intend to build my own permanent housing and mount it on my roof. I ordered two clear acrylic 80mm half spheres from a craft company for $.85 apiece. I found an idea online for a cheap housing. The professionally built All Sky camera I like is the Starlight Xpress model Oculus. It is however $1100. I think I can build one for half or less including the camera and lens using pieces from Home Depot etc. There are some cheaper ones from a company called Moonglow Technologies but they use video cameras with RCA type cable and requires a frame grabber and USB adapter to use on your computer. Their bundles are over $600. One important thing to remember is you must have a heat source. Without it the lens and or acrylic bowl will obviously dew over. I use Kendricks dew straps that were short and made for eyepieces on my now makeshift setup shown above. I intend to build some kind of heat source inside the housing to prevent the clear dish from dew similar to the dew strap concept. Note the resisters for a heat source So what size resistors did you use and how many?

The original moderator "Watcher" I think flew the coop. Istar Mike took it over then he flew the coop. The only way to flush 'em out is start telling dirty jokes!! Mike

Hi Mike
I'd be happy to moderate this forum.
Just as I do elsewhere.
But who should I contact to get the owner's permission? Istar Mike?
Thanks Chris

Go to Mike but Ales calls the shots over him. But who the hell knows who's site this is. As far as most of us care it's your call....take it over. You as a volunteer are way better than none. How do you do this stuff as I'm a computer loser myself??

Mike,
Moderators need administrative control to be able to edit posts and ban members who have seriously broken avatars.
I can remember Ales saying this is NOT iStar's own forum, a while back, when I asked why there was no response to a direct question for iStar.
The person who started the forum usually needs to give permission and share the admin password with a new moderator.
Chris
Edit: Members: Staff are shown as Ales, Mike and Watcher. I'd better get in touch with Ales, then, and throw myself on his mercy.
