A Cluster of Pearls in the Southern Skies ( NGC 3766 - "The Pearl Cluster" )

Recommended Posts

Shimmering like a pearl to the naked eye, this open cluster of mostly young blue stars ( known as the "Pearl Cluster" ) is approximately 5500  light years from Earth and was discovered by Abbe Lacaille in 1752 from South Africa.

This HDR image is constructed from 11 sets of exposures ranging from 1/4 sec ( to capture the centre of the brighter stars ) through to 240 seconds ( for the fainter stars of the Milky Way ).  Total exposure time was around 5 hours.

      Hi,
      I bought my first telescope, SW 150pds about 6 months ago with the purpose of astroimaging "when i feel ready".  So far ive used my Nikon D810 for that, and I'm now  planning on taking the step buying my first AP camera.
      My targets would be DSO's, and not planetary. I want a mono-camera, not color. 

      I want to get away with a very good camera to a reasonable price (wouldn't we all...) and in this regard I've been drooling on the ZWO ASI 1600MM Mono for some time. The price for it is in the upper part of my budget, but I'm willing to if its worth it.  I've seen from other treads that sensor-size isn't everything, and dynamic range and gain and all is just as important, but i have trouble understanding it all 100% when it's all new to me, but in my experience i am a practical person who learns things much better and faster with the gear in my hand. So without getting to technical, and staying as objective as possible - please help me with; 

      1. Is this a good camera to go for?
      2. It's sold with options of filters 1.25", 31mm or 36mm - Why these options, and what determines what i would choose?

      3. Would you go for another camera in this price range, and why? - Or to rephrase it a bit; If you were in my shoes, which camera would you og for?

      I'd appreciate any help:)

      I might add, that i understand that with my lack of experience, buying a mono-camera with filters and all might seem premature, but for some strange reason. I enjoy these "way over my head"-projects and figuring  out things as time goes - I just need some guiding in the right direction.

      I took these two photos only seconds apart. The top bit I took secondly. I’m not sure what it is I’ve captured. But can anyone tell me what it could be??

      As open clusters go NGC 2281 doesn't have much to shout about when comparing it to the Beehive Cluster or Pleaides and appears not to be a common target for Astrophotographers. However, what it does have is a name which accurately depicts what you see.
      It's a bit of a magic eye moment, but stare at the bright star in the centre of the frame. This is the 'point' of the heart which sits above it.
      20 light frames of 100 s each.
      15 dark frames,
      25 flat and bias frames.
      Taken with a William Optics Z61, ZWO ASI294MC Pro Cooled set at -15 degrees and unity gain all atop a Celestron AVX mount.
      Thank you for dropping by.
       
      John
