[SOLD] EOI: ASI120MM Imaging/Guiding Webcam

[John0z (John)]

Just a note for anyone needing to use the 1/4" photo mounting hole at the back of the camera - the hole machining seems to have been pressed such that the thread lead-in isn't there. I checked with ZWO to confirm that it was supposed to be the right thread, and used a taper tap to start the lead-in as they suggested. After doing this carefully, the camera goes onto my photo tripod adapter quite readily.

Ive been reading up on these because I didn't see this tread in time to get onboard but I might order one off thier online store. I have a few questions though.
The red an gold models are both 1.3mpx CMOS sensors, how come the gold is cheaper?
Are they cooled?
It says they support long exposures for DSOs but the longest I could find an example of is one second, anyone have any experience with this?

I'm thinking of getting one a ls a guider planetary

Difference are in the specifications... to summarize ASI120MM versus ASI130MM:

• Camera: ASI120MM vs. ASI130MM
• Chip: MT9M034 (1/3") vs. MT9M001 (1/2")
  
• Chip size: 1280x960 (1.2mp) vs. 1280X1024 (1.3mp)
• Pixel size - 3.75µm vs. 5.2µm
• Bits: 12 vs. 8

You can do exposures as long as 128 seconds. Mine gets too noisy after 8 seconds though, so I'd say that while you could probably do it, you'll need a good library of darks. You might be able to put a Peltier on the back and a fan.... maybe.

As for short exposures for planets... yep.. very good camera.


<LATE EDIT: No, they are not cooled>

Excellent, thanks! I think I'll keep my Starshoot/DSLR combo if it was cooled I'd definitely consider it, but for the price there's not much that comes close. Looks like good value, just doesn't suit my needs.

If you have the mono Starshoot, it has the *exact* same chip as the ASI130MM (The Gold one)...

Hey, has anyone been able to guide a PMX with this camera ? If so what program and settings did u use ?

Marcus.

Finally finished. A bit frustrated that I have never thought it took such a long time because two of the cameras were sent to the wrong address. However, fortunately they were found and the last one was delivered to Peter today. Thanks guys, hope everyone enjoy it and get your images soon.
For the late PMs, I don’t mind to help during next trip two months later. However, everyone could buy directly and I think a local club could organise the group-purchase to get a discount and save some shipment. And Sam is back. Contact him for any technical problems.
