Inconsistent description throughout.
Still talking about the regular QE figure and interline CCD...
The EMCCD image senor itself:

the original poster said he had no real budgetary concerns so I don't see the value in suggesting a modified security camera. In fact I think it important to point out for newbies that a Samsung or one of those Chinese Ntech cameras require some modification to work with your astro equipment. Hence it's not like you can just open the FedEx box and start imaging right away, rather with some of these cameras you need to remove Filters or solder wires and then deal with control interfaces not designed for astronomy.
Personally I do not have the patience nor interest in DIY video astronomy, that is why I went with a mallincam extreme. It worked great within 10 minutes of putting it into the SCT visual back. I am sure we will see a new generation of higher resolution video cameras for astronomy over the next few years... But for now for true live imaging, the Extreme is a great product and given the OP low priority on how much is spent, it seems we should fous on the higher end products. Heck, I am curious too... What can $5k or $10k buy in ultra high end video astronomy?

Hi Al,
Thanks for keeping a practical perspective on this :-)
I have just had a quick look at some of the scientific cameras/sensors and they look very interesting.
If I had the time I am sure I could get something operational.
However at this stage my preference is to buy a fully integrated "top end" live view cam for astronomy
It seems that out of all of the posts there are 2 recommendations for Mallincam Extreme.
I am surprised that the Mallincam seems to be the only fully integrated "top end" live view cam for astronomy. Or are there better spec'd options out there still??
cheers

A few years ago I was working on a project with one of the smaller Impactron ccd's when TI just discontinued the chip. I wasn't aware that any of the family is still available.Watch out for that one.

That's hilarious...I should have played it off instead of being a jerk. What an accurate mistake.
It is funny ... and an honest mistake. Neat way to learn about a new camera though.
We can only hope that this and other 1/2" cameras do indeed come down more in price ...

Predictable eh. Now that the water is sufficiently muddied you may be regretting asking the original question. I started with a Mallincam and seemed to have figured out how to use it and was up and running the first night. The low end cams are not turnkey and for me, I like remote control without needing an engineering degree , cooling, and long exposure capability.
I wouldn't say that the non dedicated cams are not turnkey. My camera is very easy. That Mintron model has been and still is being sold as dedicated astronomy and microscope cameras. I am fairly certain that they were sold as the Gstar for a time.

The most common mod is to remove the IR filter. On most security cameras this is a fairly simple mechanical mod, not electrical. On many cameras this makes a dramatic improvement in sensitivity.
Adding the wires for a remote handbox is a bit more involved, you need reasonable soldering skills as the points to attach to are very small. Some cameras now have an external connector and this makes this mod/upgrade much easier.
Cooling mods are much much more involved (cold finger under the CCD, physically mounting the Peltier cooler, re organizing the interior to get heat away from the Peltier cooler, etc. You need electrical knowledge, fine soldering skills, metal work skills, etc.
Re programming the DSP in some of the latest cameras is well beyond the capabilities of the vast majority of folks around here.

Thanks for all the input. It appear that although there are some very good scientific camera options the only real high performance turnkey solution that matches what I want is the Mallincam.
Thx for the help
cheers

What is your definition of "turnkey solution" ?Hi All,
Thanks for all the input. It appear that although there are some very good scientific camera options the only real high performance turnkey solution that matches what I want is the Mallincam.
Thx for the help

Any of those scientific cameras are turnkey, they don't require any modifications.
They just need a nosepiece and a power cable.
If you have the funds to buy a $10k camera, is a nosepiece a problem ? Just keeping things in perspective .

One of the previous posters referred to Princeton Instruments EMCCD cameras, used for real time video astronomy and lucky imaging.I agree. I have noted that the camera I own is sold as a dedicated security camera, a dedicated microscope camera and a dedicated astronomy camera. Mallincam is undoubtedly good, but this doesn't lessen other choices.
It doesn't get any more real time and live than that but to some Mallincam zealots, or shills, it's always "Mallincam is the only real video high performance tur(n)key cam".

Or maybe someone buy one of these for me

Actually anything on this page is acceptable

Point is there are a lot more expensive equipment out there if one has the $$$.

I have not made any decision 100% in any direction.
It just seems that the Mellincam Extreme fits criteria at a very reasonable price with minimum to zero changes.
Similar decision for purchasing my Tak Mewlon 300 and Tak EM400 mount some years back.
They were not the cheapest and also not the most expensive possibility on the market.
However they did represent a high quality turnkey solution.
I will probably put much more research into some of the other cameras but as mentioned I am only just starting out on Live Video Astronomy so have a lot to learn and understand which is why I asked for opinions and advice.
Cheers

I don't think we will see images from the megabuck systems on this forum. Kinda like seeing the 200" Palomar on the reflector forum.
What is "megabuck" to you? $3000 might be megabuck to some.

And you're right, Dwight. While I've spent a goodly amount on our hobby, all of my equipment together doesn't come up to a fully dressed Harley Davidson...not even close. And since some of those astrobucks were spent on my 8X8 backyard rolloff, most of my enjoyment is about 25' from the back door.
It's all in what you wish to make of it; spend a little or spend a lot. It's all good!

I'm looking hard at the MallinCam Micro as my entry point into this hobby. Not too much invested, but seems like its a turn-key and capable cam. The biggest thing is it will let me get everything figured out and decide if I really enjoy AstroVid and want to put more money into it. Then I can graduate to something bigger if I decide want to pursue broadcasting and more outreach.
G'day Grue.
With Video cameras it is the same as buying a telescope.
You can start astronomy with a Supermarket 70mm achromat on a Wobblitronic Mount to test the waters and see if you like astronomy, only to get frustrated at the faint smudgy views and the wobbling mount, and give up (how many millions of those cheap 70mm scopes end up dust-covered in the garage or buried at the back of the cupboard forever).
Or spend that bit more and get a simple but effective 8" Dobsonian Reflector from a Telescope shop and see some serious stuff.
The 8" Dob will keep you interested and excited more than a 70mm Wobblitronic El-Cheaposcope.
Then, when you are ready and you want to see even more detail, and go deeper, you start looking at 16" Dobsonians, SCT's, or Apo Refractors.
I believe it is the same with our Video cameras. We should start with something we know that works, and works well, or we suffer the Wobblitronic El-Cheaposcope saga and get put off.
The Micro is a fantastic 'starting point'. It's a bit like that 8" Dob. It won't show you super great detail on super deep objects, but it also won't put you off. Not like stuffing about modifying a cheap security camera which is a bit like the Wobblitronic.
The Micro will certainly whet your appetite with some terrific results, making you want to go that bit better as soon as possible.
With Telescopes it's 'Aperture Fever'.
With Video it's 'Sensor Fever'
The Micro will excite you enough to want to play with bigger toys
not put you off with disappointing results and having to 'home modify' a cheap CCTV camera.
