      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!

      Hello, i am new to this forum, i made my account here because i need help.
      So few weeks ago i ordered a USB to Serial cable to be able to Control my Telescope with my computer using stellarium.
      It arrived today.
      So i made my Star Alignment, then i plugged the cable to my Telescope and Computer, i installed the Cable driver and ASCOM Platform + ASCOM Celestron Driver.
      I started DriverConnect.exe and put the Celestron Driver i downloaded, and did the properties informations ( had to tick on "Advanced Setup" and "Show All COM Ports" ) and i put "COM8" on "COM Port", then i pressed "OK" and then "Connect"
      Result:
      Create              Creating device
      Connected           Connecting to device
      Error               System.Exception: Connect to COM1 failed, no Celestron scope detected
         to System.Dynamic.ComRuntimeHelpers.CheckThrowException(Int32 hresult, ExcepInfo& excepInfo, UInt32 argErr, String message)
         to CallSite.Target(Closure , CallSite , ComObject , Boolean )
         to ASCOM.DriverConnect.ConnectForm.btnConnect_Click(Object sender, EventArgs e) in C:\ASCOM Build\Export\ASCOM.DriverConnect\ConnectForm.cs:line 268
      Dispose             Disposing of device
      ReleaseComObject    Releasing COM instance
      ReleaseComObject    Completed release. Count: 0
      GC Collect          Starting garbage collection
      GC Collect          Completed garbage collection
       
      "Connect to COM1 failed, no Celestron scope detected"

      In Stellarium i set-up everything, the plug-in and restarted the app, then added my telescope  and i says it's "connected" but i can't find my telescope.
       
      Telescope:
      Celestron NexStar 127SLT
      The Cable i bought:
      https://www.amazon.com/Telescope-CP2102-Adapter-Control-Console/dp/B077G37VL1/
      PC Specs:
      Windows 10 Pro, GTX 970, 8GB Ram(DDR4), i7 6700 3.4Ghz
       
      Looking forward for your help, thanks in advance,
      dragorom7.

      Hello everyone, happy Tuesday.
      First time stargazer here, I'm hoping I can get some awesome feedback from you guys. 
      my fiancé and I are planning on taking a trip to Great Basin National Park from October 25th-30th, we're trying to catch the new moon, we want to do some deep sky viewing but we're having such a hard time on knowing which kind of telescope to purchase. we do have a few must- haves on our purchase, but I wanted to see what you guys recommend and what your experiences have been.
      we need a telescope that is portable
      good for deep sky viewing
      reflector vs. refractor
      and almost, but not necessarily, easy to use (we have time to learn the ins and outs of it)
      I apologize if its a lot, but trying to understand the jargon, as of now, is giving me a hard time
      Cant wait for any responses!!
      p.s. anyone ever been to Great Basin? what should we expect on our trip? its our first time going and first time doing any serious camping!!!
      THANKS A BUNCH!!!

      Hi my name is Jay, new to all and any forums, lol. Not sure where to start so here I go. I have a few questions about Sirius the double star while observing through my Nexstar 4se telescope using a 2x Barlow and my neximage burst color. While I was able to capture quite stunning results of the star Sirius, this morning before sunrise, I was curious though as to if I might have incorrectly focused my scope on the star or if this image is a clear image of the star? I will attach a brief 7-8 second video I took this morning. It was the first time I had gotten to focus my scope on the star as it kept drifting before but I solved the drifting issue as a result of improper anti-backlash. But now back to the video, was wondering if any of you could help determine if I properly focused on the star because from what I see the star appears to be in the shape of an out-of-control atom in the video and at the center it is black, is this the observing of a quasar? Thanks for all the help in advance if anyone stops by thanks for the time and efforts here's the video.
