Hi guys

well the ZWO ASI 1600MM finally arrived ( after the postal system sat on it for 3 days :-( )
I did some comparisons between it and my ZWO ASI 178MC that had been the main solar cam up till today
The ASI 1600 is a 16MPix Monochrome camera

these first two are unprocessed ( SOOC ) , just resized for the forum
and ALL images are single frame only ( no stacking)

firstly ... the ASI 178MC using mono mode in SharpCap

Now the ASI 1600MM

NOTE:, tho the SOOC image from the 178MC looks more detailed. But strong brightness variation can be seen across the image compared to the 1600MM

A picture is worth 1000 words ;)
Canon 5D3, 6D, 700D, a bunch of lenses and other bits, ohhh and some Pentax stuff ;)

What I discovered in processing was that the 1600MM image processed so much better and resulted in a significant increase in finer details :-)

ASI178 processed ...

ASI1600 processed ....

There isn't really any comparison between the two ..... the ASI1600 shows much better detail. Specially seen around the Active Region

Next post .... prominences

The limb and prominences are just so much sharper for the 1600MM

The ASI 1600MM seems to have a better dynamic range ( well I would expect it to ;-)a )
it is easier to pull out prominences and still have a non- overexposed surface
please excuse the poor editing blotchiness in the dark area around the outside of the sun ( I don't claim to be the world's best editor ;-)a )
