Revolution Imager hooked up to an analogue TV. Hand-held shots of the TV screen. Calculating up from the accumulation rate and in-camera integration gives a total refresh time of about 20s x 5 = 100s Nice thing about this set up is that the TV has a 15” screen so the images of close DSOs are an eye-popping 4-10” across. (Oops! told a lie about the TV screen - it's 15" not 20")

When'd you get the Revolution? I thought you had a Gstar EX3? Is the Revolution an R1 or R2?
Great shots!

Howie
Thanks
I started out with the Revolution Imager #1 (ICX 811 chip).
Saw Ken's review about 7 months ago and bought one straight away.
I've been tinkering with it since then and I really like the simplicity of analog to analog.
I'm always disappointed in the resulting image when I use analog to digital capture so I use the Revo mainly for observing.
I bought the G-Star so I could mess about with digital as well. Steve Massey is good bloke. He knows a bit about video astronomy and the camera looks like it will do well for DSO video and planetary asto. And $580 was about what I could afford.

Wow Robert, they look fantastic!!! Yes, I agree about Analogue to Analogue. The less the signal in converted the better. I get far better views on the cheap little included monitor than I do on my laptop, but a bit hard to save screen captures on the Monitor But for Outreach, the little Monitor or a large TV is great. Your results look better than many I've seen from more expensive cameras. Those colours in Helix! Niiiiiiiiiiice!

Thanks Ken
I think I'm lucky with the old analogue TV that I picked up from from a Sunday market ($30).
It has a lot of fine adjustment that seem to enhance the views nicely.

Yes Robert, old CRT TV's are the best, but most have gone to the tip! Ummmm . . . for our Northern Hemisphere friends: the 'Tip' is Australian for the Rubbish Dump. Probably called that because that's where we 'tip' our rubbish out

Hi guys. I was checking out your posts and Ken caught my interest with the revolution imagers; am i right you are getting these images with a 80mm aperture telescope?

Sander, I use an '80ED' 80mm ED Refractor, a 120mm Achromat Refractor, a 150mm Achromat Refractor, and a 10" SN10 Schmidt-Newtonian Astrograph. The Revolution Imagers seem to work well in all of them.

The scope I used for the shots of the TV was a Bresser 127L, 5" f9.4 achromat, with a 0.5 focal reducer. Robert
