Group purchase of tucsen cameras

I am looking for participants in:

GROUP BUY OF TUCSEN CAMERAS

The offer on the table is:
Tucsen TCC6.1ICC color CCD camera for less than AUD1000. ...
At this price we don't have to pay GST nor cost of imposing GST
on goods purchased via internet which is bonus on the top of
the manufacture's discount.

The catch is that we have to form a group of 10.

The price is a hefty 60% less than
the price offered on the internet.
It also means that it will have a good re-sale value
if you want to sell it in the future.

The camera is based on one of the most successfull CCD sensors
ever used in amateur astrophotography.
The size of the sensor - the most limiting factor in small cameras
is good. It similar to that of standard DSLR and so is the resolution.
Unlike DSLR is offers no red colour discrimination filter,
cooling, 12v power supply, controlling software with
integration capture, focusing help and sofware development kit.
It is a bit more than a "first-step camera".

Tucsen is quite a large manufacturer - mostly
involved in research grade cameras for microscopes.
It comapares and competes well with Zeiss.
It is an ISO9001 certified company (international certifiate
of quality of whole technological process incl testing and
distribution meant to be "peace of mind" certificate)
with a number of other accolites to its name.

Look for their and similar products on ebay
to judge for yourself how generous this offer is.
http:\\www.tucsen.com
http://www.tucsen.com/…/Cooled-CCD-C...en-VS-Zeiss-i…

As our dollar is plunging I would assume
that it is opportunity to kick-start
your astrophography which is not likely to be repeated soon.

More information in the attached file
Go Ozzie! Go!

BTW: Please feel free to distribute...

With regards,

Thank you Chris for sharing your find with us.

The offer looks interesting, perhaps the only thing that concerns me, and please correct me if I am wrong, is the low value of 8/12 bit ADC- it will limit dynamic range quite a lot comaring with other astro cameras with 16bit ADC.

It is a valid concern.
It may be that the whole impact of it is only in the time required to process the signal.
It is hard to believe that somebody would deliberately
lower the dynamics provided by the chip.
I will re-direct your concern to Tucsen in China

On second thoughts:

12 bit means 4096 shades of grey.
As this an amateur camera - isn't it enough?
If this applies to each colour it makes palette of colours so huge
that difference between 12 and 16 bits colour may be not noticeable.

I realise that there are 32bit colour devices too - but it is question of value for money.

BTW - I had a look at your photos. Superb. Congratulations.

Regards,

Krzysztof

Thank you Krzysztof for your kind feedback regarding my humble attempts at imaging DSOs.

Perhaps you are right that this could be enough in an amateur camera, particularly if there is not much noise coming from camera's electronics.

My camera's ICX 814 has a shallow well depth thus even with 16bit ADC, it gives only about 10,000 different values /shades of grey per pixel (given that my calculations are correct).

So again, this seems like a great opportunity to relatively cheaply acquire a nice camera for astrophotography.

12 bits is all that most astro cameras can actually do - they are generally gain boosted and sampled at 16 bits, but the lower bits are dominated by meaningless read noise in all but the most expensive ones.

Warranty: Tucsen respects 2 year warranty.


The response I got from Tucsen is similar to mine, but
it is less scientific, more commercial:

Quote:


2.Generally speaking,the dynamic range of 16 bit camera will be better,but you do not need worry about this.

We sell this camera to canada and England astronomy amateurs every year,they are all satisfied with this camera.

And i have sent your the sample picture,TCC-6.0ICE is really suitable for your application

End of quote


Interesting to hear about your experience with well depth.


So far I got 5 committments.


Regards,

Krzysztof
