CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!
Here's the Eta Carinae in H-alpha. Very good guiding and seeing. Apologies for the file size - 220KB, but a smaller size didn't seem to do justice to the detail in the image.

Fantastic! any LRGB version of the image :-)
Can you explain a bit on the fabrication of the Artemis camera? how difficult it is to fabricate it and how much was the total cost? how does it compare with ST-7e or ATIK-2HS?
The camera was GBP 800 (or S$2400) for the kit. Price has gone down to GBP 765 now. Assembly was not difficult, but you need to be confident with soldering and using a multimeter to check voltages etc. Some pictures of my assembly is on my website at
Also, a 12V and 5V power supply is needed. I made mine from a standard PC PSU.
It's a 1.4 megapixel CCD, so much better res than either the ST7 or 2HS. The chip is very low noise and fairly high QE so performs well. The raw images are cleaner than the ST7, but with the small pixels the well depth is not as great.
wow...thanks Tan Guan...you really did justice to the ED80 in a way I never can...thanks for sharing. and I think the collimation from vince snr helped too! do share more of these wonderful shots in future...
I have "downgraded" to a WO 66mm for super portability but oddly, the scope cost more than my ED80! now I miss the aperture (but not the OTA size!).
ok..so as not to go off topic, do post your images under new threads with the relevant subject titles....
cheers and welcome back!

Thanks TG for the info. I noticed that the camera is identical to ATIK 16HR. You saved $900 by buying the kit!

Yup, identical camera and capture software from Jon Grove and Steve Chambers. Only the colour is different. Good thing about building your own is the mods you can make. eg for use in Singapore I would get a higher power peltier. Camera is only happy with the CCD below 10 deg C, and you will barely get that with the standard one.
