The Jewel Box ( NGC 4755 ) is an open cluster of mostly hot young blue-white stars that appears to the unaided eye as a bright 4th magnitude star close to the Southern Cross. Only visible from southern latitudes, the Jewel Box was first recorded by Nicolas Louis de Lacaille during his visit to South Africa in 1751 and was later described by Sir John Herschel as "a casket of variously coloured precious stones" - hence the name "Jewel Box".

      Hi all,
       
      I'm pretty new to astronomy and need help deciding if I should buy the following telescope or not, mainly if there is anything visibly missing by looking at the photos?
       
      Thanks in advance!

      Skywatcher 150/1200 f8 planetary Newtonian.
      Bought this originally intending to set up a planetary rig but circumstances call for sale.
      Will come with eyepieces and a collimation eyepiece. Not used by myself and has seen very little use. Mirrors in good condition
      Collection only
      £50

      Having upgraded from canon 1000D to Nikon D5300  how do users of the 5300 find it for Astro I will be using with APT , and how do you take flats as I can’t use Av mode as there is nothing in tools menu to choose no lens ,  do you use in manual mode  and look at histogram ? .

      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.
