Hello all,
    I have been testing the New ASI 1600GT for about 6 weeks I tried testing from New Jersey but the weather has not cooperating so I sent it to Florida to a friend of mine David Webster who tested this camera in the same scope that I would of and we were very pleased with the outcome. Attached you will see a Narrowband image of the Tadpoles (IC 410) that was processed in PI only.

 

I personally like the idea of an internal 5 position 1.25" filterwheel.  The measurements of the camera are as follows 4.3" X 4.3 X 2.3" not including the nose piece Fans are quite I did capture all the images with SkyX but I also tested it with Sharpcap, Maxum as well as ASICAP software and I had no problems while testing.

 

 

Tadpoles

 

14" LX850 F8 native
1600 mono - Gain 20
Paramount MEII - Protrack - No guide
PixInSight - Full process
HA - 18 @300sec
SII - 20 @300sec
OIII - 20 @300sec
Bias - 100
Dark - 20
Flat - 20 ea.

 

The Camera has an internal 5 position filter wheel which worked flawlessly I did get the cooling down to 40 below ambient for testing purposes but did all of my testing at -20.

I also just decided to shoot the moon for giggles because all these images were done with the moon lurking in many different phases.

 

Because these moon images were done spontaneously and not part of the testing  I really don't recall the setting but I'm pretty sure I was .005 and stacked 20

Hopefully I have covered everything for now but weather willing I plan on doing LRGB soon.

Hi einarin,

    

      There is no info. on this camera yet but it looks like it will be introduced at NEAF.

it is a "copy" :-) of Atik ONE body. I was very happy with my Atik ONE featuring ICX694, but sold it due to lack of time to do any AP. Now I'd consider this ZWO ASI One with the PANA1600 sensor and 5 only FW (because for RGB work I prefer one shot color cameras nowadays so I need only few filters for narrowband).

 

AFAIK there is no official information out yet, but I noticed this product on some video last year (along with some 2" filterwheel I think).

Hello Konihlav,

 

       The bodies are somewhat different but I can tell you this one will be a keeper for me.

Hi Joe

 

ZWO is a non-stop invention machine!   The twin fans look cool, do you know if the "GT" will have superior cooling to the other 1600 based cameras?   Also can you elaborate on any other additional features... is the DDR buffer the same or larger?  Looks like the same 2 port hub?    5 position wheel, but will it come with 7 or 8 position in the future?  Last but not least, it would be great if it had a shutter!  ZWO has taken some flak for constantly improving on the original 1600 based camera, personally I am thankful for their pace of innovation, but I think it will be important to get this camera out to the market with as many features and capabilities as users would want to see, rather than take that risk of version 1,2,3 etc...

 

Looking forward to seeing more from this little baby!

let us know also the dimensions of the camera body...

and if the internal FW accepts only 1.25" or if it also accepts 31mm unmounted filters (like ZWO's mini EFW) ?

I assume it won't accept 36mm unmounted filters?

and am sure it wont accept any larger in the future due to the all in one design.

thx!

BTW I was also considering to beta test this one, but due to lack of time I gave up (and am a happy keeper of the ASI094MC Pro that's just a great and wonderful thing - but still missing some ultimate mono camera :( )

Other than what appears to be better cooling what is the advantage?  It still seems too large an obstruction for Hyperstar and otherwise the ASI1600MM/miniEFW is a pretty compact package to begin already.  

 

Does it reduce the distance between the 1.25inch filters and the sensor?  If it does that would certainly reduce vignetting like in the QSI bodies and would be a nice improvement.

Hi Mike,

 

      Not that I would use it on a Hyperstar or RASA telescope but it's not wider then My Canon or Nikon and some people use them with Hyperstar. and as for the filters being close to the sensor I can tell you they are right up against the sensor unlike my 1600 mono with an external filter wheel.

 

   This camera is a good fit for those that want an internal filter wheel and that't what I was looking for. 

 

   As you can see below my arsenal is pretty extensive and this camera may make me thin the herd.

 

Thanks,

Joe

The dimension are as follows  4.3" X 4.3" X 2.3" The camera I tested only had a 1.25" filter carousal.

At least you can use less expensive 1.25" filters.  I use 2" now with external filter wheel on my QHy163M.  How easy is it to change the filters?

Hi,

 

Perhaps I have overlooked it.

 

What is the image size in Pixels and Pixel size in microns ?

Hi Mike,

 

  It's only 4 screw to access filter wheel.

Thank You waytogo.gif

note:  this is the EXACT same camera as the ASI1600 mono.  It is just being offered in an more ergonomic form factor and has an extra fan. Apart from that it is the same.   ZWO needs to offer something more here imho for this to be a product one would want to buy, I mean unless they price it below the effective cost of a 1600pro + EFW5 wheel   which is probably unlikely... Soooo....  what do they need to make this a winner?     Well in my opinion...  1) a Shutter  2) option for 7 position wheel  3) integrated OAG, 4) maybe 4 port hub?  and 5) 512MB buffer

 

absent a few of the above additional add-ons  I really don't know why you would want to pay up for an integrated camera + FW  -- i mean maybe... but would you pay more for it than the component parts?  If however it has the additional goodies listed above then I think ZWO can charge considerably more and get it...   but hey this is just one person's view...

What would be the best way to populate a 5 pos filter?  

 

I was thinking maybe RGB, OIII and Ha and not bother with L. (  You can create a synthetic L ).

 

I notice others use LRGB and Ha and then have to open up the filter wheel to install OIII.

 

EDIT: Sorry did not mean to hijack this thread, I'm hoping to buy one of these as soon as prices are available.

I go simple with LRGB plus one open spot. I like to leave one open so that I can puffer the sensor off without having to open the camera.

I notice it has an ST4 connector.  Can't imagine why you'd use a camera with built in filter wheel for guiding!

Some camera drivers allow the imaging camera and ST-4 port on that camera to "relay" the guide corrections on behalf of a guide camera without an ST-4 port. For example, QSI cameras can do this. It's a pretty rare hack in the age of PulseGuide but folks do it on occasion.
 
I suspect, though, that it might just be an artifact from an earlier hardware base that hasn't been streamlined away yet for the production version. Kind of like what happened with the regular 1600.
