- Andromeda Galaxy
- field flattener
I used a Nikon D7200 prior to receiving this for my birthday this year. What a great camera, the cooling system is really awesome too. I cant utilize it so much here in South Florida, but it works great. Highly reccomend. Im very happy with the 4 ZWO products I currently use (AAP, EAF, ASI071, 120mm Mini). I used it with my 6SE on a EQ6 mount.
First Light with ASI 071 MC Pro - Great Results
Put this behind a William Optics ZenithStar 73 APO, using a Williams field flattener, Baader Moon and Skyflow filter then centered it on the Andromeda Galaxy. Settings were 180 gain, 120 sec captures, cooled to 5C. 80 images captured and 76 images stacked with Deep Sky Stacker the post processing done in Photoshop under. Viewing was clear with Bortle 7 sky and full moon. I'm quite satisfied with the performance of the camera especially under the viewing conditions.
ZWO ASI071MC Pro Cooled Color CMOS
Love this camera, having lots of fun with it.
ZWO ASI071 Pro Cooled Color CMOS
have shot this camera about seven sections and the pixs are great. niece detail and color. also i use it for star ligament so no need for spotting scope.
Upgrade from DSLR
This is definitely an upgrade and a bit of a learning curve from the DSLR. I pretty much had to throw away a night of imaging to work out a lot of details but that is to be expected. I'm using a Celestron 9.25 with the 6.3 reducer. I had done some research indicating that the proper back focus from the end of the reducer to the camera sensor would be around 105mm , so I loaded up on spacers. This turned out not to be so. After a great deal of experiment I landed at about 65mm before the vignetting finally subsided. Most of the learning curve has been around learning how the camera interacts with the computer and whatever programs you're using. To be honest, I still haven't worked all that out. Finally got a whole night of imaging in, though not ideal conditions ( 25mph wind gusts and a bright moon for half the night). I was blown away by the difference in image quality from the DSLR even in less than ideal conditions. Having never dealt with FITS image format there have been a number of other hurdles in the processing of the images that have been hair pulling. Deep sky stacker and pixensight both seem to read the images in gray scale and I had to figure out how to debayer. That word never enters your vocab with a dslr. But I'm sure I will figure all this out in time. That is half the fun of this hobby. Overall great camera so far. Wish I knew how to add an image to this review.
