Recently i bought this brand new camera from David Hardie when he was doing a big sell out of some really nice items in excellent offers !!!
Unfortunately the camera although brand new doesn't serve my purposes so I decided to sell it at exactly the same price which I bought it from David , it was a really special offer 🤪
The camera new costs £1685 and I will sell it for £750 to be fair....🤪🤪🤪🤪
Camera comes with all its extras and case in absolutely brand new condition....!!!!
Info from FLO site :
Postage expenses are on me, secured package.
Paypal accepted ,just buyer pays the fees.
If payment is in EURO we will just calculate the daily exchange rate at Xe.com.
Many thanks !

Hello I'm new to this forum, greetings from rainy Luxembourg.
I see this subject has been well covered already but I have a specific situation I need help with. I have a f/3.67 20" (508mm) Newtonian,coupled with a TS-Optics Coma Corrector 0.73x Reducer, and an Apogee U4000 CCD (chip size 15.2mm x 15.2mm). I understand I need an over sized secondary to take full advantage of this f/2.7 super fast setup, but exactly what size secondary should I order? This setup has disadvantages that I cannot change like unforgiving collimation and focus (and some coma), but this is the one thing I can change for optimum performance. Can anyone tell me how to calculate this or, better still, calculate it for me?

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.
