I cannot get my starry night pro plus 7 on an iMacOS high Sierra computer to communicate with the NexStar+ hand set on a CPC Celestron telscope.
I have upgraded the handset from version 4 to version 5 and bought a new usb data cable , plus a 5-Pin Mini B Cable to fit into the NexStar+ handset,all to no avail. Please help!

Can we establish how your computer communicates with the Nexstar+?

On my setup, a USB to serial converter plugs into the laptop. The converter requires a driver. A serial lead (9 pin one end, telephone style the other) connects to the handset bottom.   I need to tell the laptop which serial port I want to use, otherwise the setup doesn't work.

Newer handsets may have an all-USB connection - I'm not sure.

It seems a great idea in theory, but I have stopped using it as more bother than it was worth. Most of what I want to view is either in the handset database or can't be located in the planetarium program (Stellarium in my case).

Thank you for responding Geoff. The old handset NexStar version 4 needed the converter and RS 232 cable into handset socket and usb into computer and that did not work either. I now have the newer version 5 handset which has a mini B usb socket at the handset end and ordinary usb cable to the computer. The starry night software does not give the option of using a usb port. I would the two to communicate if only to download new firmware to the handset.

Why did you upgrade the handset? (Please don't say 'because you could' ?)  Was it because it wouldn't connect to the Mac?

Until a Mac user answers I would suggest going back to the previous version handset, or trying a more co-operative program that supports USB ports.  Or get a Windows laptop, which should run a greater variety of astro-related programs.

You should be able to connect for downloading firmware via USB independent of the Starry Night. (my advice here is don't download upgrades unless you positively need to fix an issue. Save a lot of aggro and lost time that you won't ever get back.)

      A week or so I good I did some preliminary research for a decent 32mm eyepiece.  Looking at my results today I went for budget but decent.
      I have ended up with a shortlist of: -
      Revelation 32.0mm Plossl Eyepiece 1.25"
      Celestron 93323 1-1/4-32 mm Omni Series Eyepiece
      Baader Planetarium 32 mm Classic Ortho Eyepiece
       
      My query today as I recheck my findings is the Revelation one.  That is coming up at almost half the price of the other two (at www.telescopehouse.com)
      But this eyepiece made my shortlist due to positive comments about the GSO build.
      So, finally, my question, does the purchase price suggest this 32mm isn't a GSO?
      No rush here.  It's a wish list not a need list - as I remind myself... lol

      So the little circular bubble level is weak.
      But how to improve the levelling stage a head of the alignment stage?
      A traditional level like this one
      Or a simple multi purpose one like this one?
      And we do this on the tripod before adding the mount & OTA?
      The mount looks gently curved. How do we check that for level or do we trust the ‘fit’?

      Hi 
      I’m attempting to get back into astronomy, previously owned a 150pl reflector but parted company with it several years ago, I like the idea of a Cassegrain style as one of the big factors Of letting the 150pl go. was storage and transportation of It! I am interested in mostly visual observations but would look to take a few pictures here and there OF planets and easy nebula/DSO., I feel that a Schmidt-Cassegrain would be the best suited, my main stumbling point is should I get the 5 or 6 version. Is the 6 under mounted? And is it worth the extra cash, obviously there’s a higher light gathering power on the 6 but would it be much better than the 5, I see that the % of lens obstruction on the seems high! As the secondary mirror looks to be the same size on both 40% vs 14%! Obstruction by area. Any guidance would be very appreciated. I’m not against the idea of upgrading the mount in the future to a eq5 maybe? But want in usable to start with.

      Hi all, looking for some help please! 🙏 I have a wedge for my 8SE and when using EQ North to align it, it says it is slewing to Vega but ends up all the way over at Polaris!?  Any ideas? 🤞🏻 Thanks in advance! 😊
       
      I have updated the firmware, Mount is pointing at north, have inputted my latitude and longitude, I have tried picking the nearest city too and nothing seems to work! 😟

      Hi all.
      I have just bought a Celestron 18771-CGL power tank to allow me to get out to the dark skies of the South Downs with my Nexstar 8SE. This is a great bit of kit because it's so light and portable and powers the scope for hours no problem. However, I've also been thinking about getting a dew heater and the only downside of the power tank is it's lack of a second 12v output. I was looking on the First Light Optics website and they sell a DC splitter cable to allow two devices to be powered from a single output. I'm not an electrician obviously, but logical tells me if the dew heater controller is also a 12v device there should be no problem running both the scope and the heater at the same time other than draining the battery faster. Is anyone using a splitter cable in this way? Or can anyone confirm my logic is flawed?
