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 everyone!
      I was lucky enough to spend Easter in Mauritius and managed to get a night of imaging in despite the tropical night time clouds! As someone who lives in the Northern hemisphere, the Carina nebula has always been a target I've coveted, but during my holiday, I also loved Crux as prominent constellation in the Southern sky. So when I ran into polar alignment issues with my Skyguider Pro, I decided to play it safe and go for a wider field, capturing both those targets rather than focusing purely on Carina as was my original goal.
      This was shot from my father in law's rooftop in Bonne Terre, Vacoas, Mauritius and my basic polar alignment meant significant field rotation, but I still got some usable data. Cropped, processed and finally upsampled.
      Data was shot at f/2.8 with a 50mm lens, unguided on an unmodified Sony a6500. 174 lights at 30 secs each = 1.4 hours of integration. Bortle 5.
      From the colours it looks like these objects sit right on the disc of the Milky Way and I know there is more in the picture I haven't mentioned!
      Thanks for looking!

      For deep sky observations, can you make suggestion which will be more fitted with my behavior: mobility is not a big concern as a least 11" aperture is must whereupon computerized stuff is no good choice for me.

      Hi guys
      I'm breaking the cardinal rule here of posting late at night, right after finishing PP, so let's see what sense the dawn brings! 🙃 
      I shot this in the early hrs of 29th of March. There was no moon present (i think!) and conditions were pretty good, AFAIK. 
      This is 28 x 360s, so about 2.75 hrs in total. Taken as usual with the D5300, IDAS-D1, and SW 80ED. 
      APP used for stacking and gradient reduction, everything else done in PS. 
      Would have liked twice, or 3 times, the data, but it's just not happening, so i've just decided to process what i've got. 
      Thanks for looking, and all CC welcome as always 😀

      Hi guys,
      This is the first lights of my ASA 12"N f/3.62 (purchased in 2007) with my Moravian G4-16000 CCD camera using one KAF-16803 chip of 36mm x 36mm (4K x 4K).
      The adjustments, collimation, ASA OK3-Z pression screws, asked a lot of attention.
      For a precise collimation, i use the CATSEYE XL & XLKP kit.
      This is the first 3hrs of exposures taken the last weekend in one night. The second night was too windy unfortunately.

      Hi,

      I'm totally New to this hobby and i'm having trouble understanding something in stellarium.
      I have ordered (not recieved) a Sky-Watcher Explorer 150PDS, which has a 25mm eyepiece 50degrees FOV as a default.
      I also have a Nikon D810.

      I wanted to get an idea of what my field of view would be with the 25mm eyepiece (30x on 750mm focal length), 
      and also what it would be With my Nikon D810 mounted shooting prime Focus - no eyepieces.

      What surprised me was that it wasnt much difference between the frame and size of the object i get with 30x magnification (25mm eyepiece), and what i get with the Nikon D810 mounted. 
      I dont get this. What magnification do i get With my DSLR mounted with no eyepiece?
