THIS ITEM HAS NOW BEEN SOLD.
This listing is for my personal camera (Kayron from Light Vortex Astronomy). It is a QSI 660wsg-8 monochrome CCD camera with the onboard 8-position filter wheel and Off-Axis Guider (OAG).
The camera has been extremely well kept and cared for. I am supplying them in the original QSI pelican case, alongside the power adapter (with EU and UK plugs), a new USB cable, the QSI Allen wrench set, the 2" adapter for the camera and the guiding cable. The camera's condition is as-new.
The QSI 660wsg-8 requires a single USB connection to control both imaging and the filter wheel. It also cools to -45°C below ambient temperature. The CCD sensor is Sony's ICX694, which is extremely low noise requiring no darks whatsoever and having peak Quantum Efficiency of 77%. The readout noise is also extremely low at only 3.97e as per my own measurement. Its full well capacity is of 17,719e, also as per my own measurement. For more information, please see QSI's website:
Please note that this camera currently retails at just over £3,700 from UK suppliers, €4,400 from European suppliers or $4,200 from US suppliers. Payment is preferred via bank transfer but PayPal is OK with an extra 2.9% to cover PayPal fees. I'll cover postage to you via tracked Courier.
I welcome any questions you may have regarding this listing. Thank you for looking.
I have decided to buy an OSC CCD and have narrowed it down to a choice between AS129MC Pro and the ASI183MC pro. I would welcome some advice and comments on my reasoning.
First, I know there is a good argument for going mono, but that’s for the future. I want to take it one step at a time. I am just about getting my head round guiding.
My kit is a HEQ5-Pro Rowan Belt modified with mainly Explore Scientific ED APO 102mm f/7 focal length 712mm permanently mounted on a pier.. I also have a Celestron C8 but that’s for later. Until now I have been imaging with a Canon450D moded and a Canon 2000D. I have an ASI178MC (not cooled) that I bought to experiment with last year.
I also have travel gear consisting of an AZ Gti WiFi on which I sit my DSLR with a Cannon 300mm lens, which is great for big targets like M31, Rosette Nebula etc
After extensive reading on Forums etc I am leaning towards the ASI294MC-Pro. (but tomorrow I might change my mind)
My reasoning is that the ASI1294 has a larger sensor size, 14 bit ADC vs 12 on the183; and larger pixels, and a greater full well capacity. So this means that the FOV will be only just a bit tighter than the my DLSR so with my ES102 I can still get good images of larger targets like M42 especially if I add an FR. Without the FR I can get smaller targets. I should also be able to use it with my Canon 300mm lens when traveling. It should also work well with my C8 when I start using that.
I have also read that the larger pixels at 4.63um are more forgiving than the ASI183 that has 2.4um pixels especially when focussing. The ASI294 also has a much greater full well capacity, in theory providing greater dynamic range and less chance of blowing out stars.
But I have a nagging doubt, because the ASI183MC pro although it has a smaller sensor size, is still quite decent and the tiny pixels mean that it has a resolution of 20mp compared with the 11mp of the ASI1294. So am I turning my back on greater resolution for my shorter focal length scopes? In the world of DLSR 20mp beats 11mp any day. Plus the ASI183 has an 84% QE!
What brought it home was a test exposure I did with the old ASI178MC that also has 2.4um pixels, but a much smaller sensor. Using the ES102 I took 50 x 30 sec exposures of M27 (dumbbell) and compared them with results from the 450D on the C8. The FOV is the same, but the 178MC results were so much better.
Any views most welcome.
I have recently bought a Orion Starshoot Autoguider. I downloaded phd 2, eqmod and ascom stuff. After a small research I found out my mount (exos 2 gt) doesn't support computer acces without firmware upgrade and fancy cables but I have the st4 port so it shouldn't be a problem. In phd I choose camera as Starshoot Autoguider and mount On-Camera. Aux mount and AO are both none. My wiring is one cable to pc from camera and another to st4 port from camera. When I started looping I selected the star with no problem. I choosed the one star alignment option from my hand controller and after centering the Archturus in the middle of view I pressed ok and it was successfull. I started guiding and after a while I get the error: RA calibration failed star didn't move enough.
I have a question about filterwheels; SBIG filter wheels specifically. As far as I know they are the only ones that really use the 8 position filter wheels. So I have it loaded with L, R, G, B, Ha, OIII, and SII. So that is seven filters, what goes in the 8th slot???
Thank you for your insight,
I have been trying to connect my QHY FW2 to APT and even though it establishes connection, I am unable to rotate the wheel with the software. No clue whats happening. The wheel is powered, connected to CCD and APT. But nothing after that. Someone please help
