Quote:David, . . . Another suggestion is the panasonic scb-2000, because it has up to 8 second intengrations. That would make the mallincam croud a little jealous since you could capture objects MUCH quicker. Not as colorful but hey, it's nearly instant fir most deepsky objects.
Quote:LOL! I am doing this on the cheap... Actually, my budget for the necessary starting parts has run dry before I got started thanks to a BIG mistake by a company that charged me several thousand dollars too much by accident and now I am waiting to get the charge returned ( They are OK about it and acknowledge the mistake ) - But it's really messed with me ordering some of the extra parts I need. Anyway, yeah, expect ultra-cheap stuff... And very unconventional, with PC based control of the camera and adjustable high-resolution exposure tubes - but I still need to get and test the camera first.So far, the equipment list for this project that I have collected and prepared;1 x P8079HP Cascade Tube ( Gen1 )1 x xx1130 distortion-corrected 18mm lightweight cascade tube ( Gen1 )1 x Omni IV level Litton M869 Gen3 tube. Similar to MX10130 in size. 1 x MX10160A style tube. ( or MX11769 ) 1 x xx2500 ( MX9644 style ) adjustable gain Gen2.1 x Gen2+1 "Hybrid" tube... Assorted C-mount adapters and mount parts.Battery boxes ( commercial ) and switches and stuff.So I am planning a Gen1/2/3 project with sufficient information to use whatever tubes the user can get and I'll explain the photocathodes as well. I'll write up a technology primer too.As for cameras? Think small, like Microscope... Setup like an adjustable focus relay lens. But I need to find the right one. eg, http://www.ebay.com.au/itm/2-0Mp-NEW-DIGITAL-USB-MICROSCOPE-500x-8xLED-Camera-/110728070990?pt=AU_Business_Industrial_Medical_Scientific_Equipment2&hash=item19c7e8474e#ht_4005wt_905It's a 2.0 MP ( 1600x1200 ) image sensor with USB interface and direct-to-PC attachment with software and exposure times out to 1 second and it's very lightweight. With modification, it looks like it might be perfect for what I'm planning. ( Feedback is OK - Image Intensifiers I know, the needs of the astronomy community, I do not ) I still need to buy it yet and determine it's suitability... Also I need to make whatever I do make usable both with eyepieces and camera. RegardsDavid,

It's a Samsung, not a Panasonic 2. The Philips ToUcam 840 Pro II and the SPC900NC are both fantastic webcams. But no-one has worked out how to do a Live broadcast thru NSN with one modified for long Exposure yet.3. No, the Mallincam crowd don't get jealous of the Samsungs '8 seconds' capture I use both the Samsung SCC-A2333 and the Mallincam Xtreme together switching betweeen the two and they really are chalk and cheese But Bang for Buck the Samsungs do a good job. But Jealous? Not on your Nelly
Quote: I am currently trying to adapt my p8079hp for astronomy viewing. I have encased it in pvc tubing and will employ a separate mount to mate it to my f/4 sn 10". Has anyone combined this nv tube with a telescope, and with what results? I am to test it tonight with a ~10nm h alpha filter. Any suggestions?
