Hello,

 

Last weekend got a clear night and decided to take first light with ZWO ASI533MC Pro. The Moon was quite near to full, but still was giving around 1h 30 minutes darkness - good chance to make some tests of the ZWO Duo-Band Filter too. Additional performed test was the usage under the skies of APT's support for the ZWO native driver

 

As target picked-up an object that is well known with idea that can show the performance of the camera itself. BTW I have never imaged the Rosette so far, and it is still in my list for a narrowband attempt

 

The first revision is comparison of single frames, auto stretched - one when the Moon was high above the horizon, the second was few minutes after its setting.

 

 

The second revision the processed image taking all available frames 50 with Moon and 11 without. Used is the unity gain for the camera - Gain 100, Offset 70.

 

Having some experience with DSLRs I'm very happy with the results from ZWO ASI533MC Pro. No darks or bias frames are applied! Just dithering and cooling to -20C In the net saw some opinions that this camera is good entry level for images coming from DSLRs. There is need to make few serious sessions without Moon, however on this stage, my opinion is that ASI533MC Pro is great OSC that can give very good data when there is no time to make LRGB with mono camera. My plan is to use it as main imager during astro parties

I wish my ASI-533MC-Pro would hurry up and get here !!!!

 

I feel a trip to the dark site coming on.

Ivo,

Very Nice!

 

My 533 arrived from HighPoint on Saturday and, of course, nothing but clouds/rain/snow for the rest of the week

 

Also - THANK YOU for APT (and the bonus Christmas present). I love it.

Many thanks Roy!

 

Congrats on the camera! I think that we will be quite happy with this model The absence of amp-glow sold me in no time It is the CMOS camera I have been waiting for...

Hello,

 

This is my second round of the ASI533MC Pro testing. Again a popular target is selected in order to give better base for comparison. In this project didn't use any filters in order the camera own performance. Other change is that the gain is a bit lower than the unity, trying to increase dynamic range.

 

As additional note, have to add that 2/3 of the frames were taken with moderate sky This winter was not generous and had to use what is given...

 

I'm quite happy with the result The camera is sensitive and gave deep look on the object even with the smallish 80mm refractor.

 

 

97х5min = 8h 5min, gain 75, offset 70. WO 80FD, WO FRII, CEM60, APT, PI, PS
