ASI1600MM Pro unboxing, cooling and dark frames test.

Recommended Posts

Hi all,

Since a few days, I'm the proud owner of the asi1600 Pro.

Performed some first tests, see: https://youtu.be/hHJBbpNoi2I

 

I used SGP Pro to test cooling and dark frames (2m and 5m) on unity gain settings.

Is it ok to use unity gain (139) setting or should I use high dynamic range?

Also, this is my first mono. Do I need to take flats/bias frames for each filter separately?

And how could I stack either broadband or narrowband images? I'm used to deep sky stacker.

Cheers,

 

Wido

I use 139 for almost everything. Its a good starting point.  2m for LRGB and 5m for narrow band is ok.

Dont use bias with a CMOS camera.

You will most likely do better with flats for each filter.

Adam, Rob,

 

Thank you so much for the valuable information.

I'll try to take flats for each of the filters and make a dark library. 

And I'll check out Jon Rista's website. Thanks!

This will be my first advanture with a mono camera ?

Hi all

Just finished my first narrowband session imaging the Cresent nebula. Used a standard unity setting of 139. I'm really impressed by the h-alpha images. I started out with a simple workflow with the new zwo 7nm filters, using deepskystacker and Photoshop to create a combined image.

This was my very first narrowband session...still have a lot to learn :-). Tips are welcome!

I like that you jumped straight in with a full tri-filter image :)

Hi Adam, 

Yes, I'm probably moving a bit fast and now I'm in over my head, haha.

have to learn how to process this stuff :-).

collected some more data and tweaked a bit more. Neutralised the stars by taking out the green colors. And added clarity to the surrounding nebulae. I'm amazed at the detail I get in my red zone. This is addictive.

Flats: The official answer is that you should do flats per filter. In truth I usually find that a luminance flat works for everything. On the rare occasions when it doesn't I do it properly!

      Hi everyone,
      This has been on my hard drive for some months, so nice to have finally got round to processing it! Shot over several nights in January in my back garden.
      NGC 281, also known casually as the Pacman Nebula, is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm. It lies about 9,500 light years from us and is 48 light years across.
      As the final version, I've gone for a crop, which I think holds up well, though I'll include the wider fov version in the next post.
      I used a more natural colour blend for this image:
      R = 76%*Ha + 24%*SII
      G = 100%*OIII
      B = 85%*OIII + 15%*Ha
      For some reason, I was not expecting much from this image, but the result looks like it will be one of my favourites...the narrowband data was really good!
      Captured using APT, stacked using APP and processed in Pixinsight.
      5.4 hours integration time.
      Link to full details and higher res version.
      Thanks for looking!

      Hi, this question has probably been done to death here, but can I ask the community to help me decide on a new camera?
      After struggling with my very glitchy QHY5LIIc camera for a while, as well as having a forced break from astronomy, I have decided to get a new camera. After all the problems I've been having with the QHY, I really don't want to use this manufacturer again. I know lots of people use them quite happily, but once bitten ...
      I have been looking at the ZWO cameras - OSC, as I haven't the time, clear skies, or patients to do LRGB imaging!
      I have about £250 to spend, which I may be able to push to £300 if I wait a bit. ? So I've been looking at the ASI224MC, ASI290MC and the ASI178MC cameras.
      I mainly do planetary/Luna imaging, but I have also dabbled in a bit of DSO and would like to continue with both. I have a C9.25 and a ST80 guide scope. I know these aren't ideal for DSOs but please humour me!
      I think from the specs/information that the 224 is probably the best option. Although the resolution and QE are the worst of the three, the well depth and read noise are the best and the fps is pretty good too.
      I don't know if there are better/cheaper cameras using the same chips, such as Altair's range. I just don't want to make the same mistake that I did with the QHY!n
      Any help/advice you can give will be much appreciated.?

      I have discovered that the Nexstar+ handset of my CPC800 has a Camera sub-menu, apparently for controlling a camera.  This is not documented in the CPC800 manuals and I could not find any instructions online.  All I found on the Celestron website was a picture of a C8 SE with a camera attached and a cable leading from the camera to the aux port.
      Has anyone used this feature, or have some instructions?  Is it really useful for anything?
