Today I like to present the first and second light with my new camera, ASI 1600 MMC.

First an emission nebula in Cepheus, SH2-140, 11 hrs. HaLRGB:

Second the Coma galaxy cluster Abell 1656, 13 hrs. LRGB:

The picture also shows the Quasar QSO[HB89] 1256+280. With a redshift of 2.66, this quasar has a distance of 11.3 +/- 1 billion light years. It is thus located shortly after the Big Bang and thus the observable part of the universe:

I hope you enjoy the images as I did. The camera is worth every cent.

 

Cheers Jens

Jens,

Wow...those images look outstanding.  I'm attracted to the idea of using short exposures and you've done a great job with it.  As usual, your processing looks perfect.  Very well done!

  Never had luck with this camera, but your images look great Jens.  Tempting to go back and try again.

Fabulous images! The Coma Cluster is on my list of objects to image - as soon as the Full Moon wanes. Now I have a solid reference image to gauge mine against.

Jens, these are great images. You must have some wonderful skies, those colors are so rich! And your stars are impeccable.

Very nice - you clearly understand how to use the new tech to its fullest.  Hopefully more people will learn you don't have to spend so much on a camera these days to get top notch results.

Thank you all for your feedback. Highly appreciated.

John, more or less short - in any case shorter as with my Atik. I made a test with 15 sec. exposures on M 101 and had 630 subs to integrate in Pixinsight. It took 2 hrs. and the result had strange stripes in the image. I don't know why. Calibration with bias, darks and flats as usual. For now I will use 180 sec. subs as a standard for LRGB and 300 sec. for NB.

Jon, not really. My best SQM values are around 20. Normally around 19.6

Mike, I aggree. The cost of the camera is not the factor. Care and attention during exposures, keeping the telescope, mount and the rest of your equipment under control and last but not least good skills in image processing is the main thing. On the other hand hiugh quality (and expensive) equipment does no harm :-)

Sam, I was really sceptical at first regarding the new CMOS chips. I tested the ASI 1600 MMC one year before and was not satisfied at all. On the other hand I saw more and more superb images from some photographers with that camera, so I gave it a new try. And what should I say, either I was too unexperienced last year or the newtonian is the better choice for the ASI instead of the small FSQ85 from last year. For my part I will use the ASI now as standard. The Atik 460 Exm will take a break now :-)

I like both images but the second one (Abell 1656) is fantastic!
