The Spectacular return of The Sphinx


Recommended Posts

Well, I was finally able to put the newly repaired Sphinx through its paces over the weekend, Saturday night turned out a bit of a bust weather wise, however it gave me the advantage of already being set up for the following evening which was a completely different story.

Sunday...?   Transparency not all that great, (perhaps NELM variable 3 to 5) and with a half moon shining, not ideal conditions for deep sky observing, however was still able to bag a few  old favourites, including M53, M13, M92 and M51, M81 & 82.  Then spent the next two hours exploring some galaxies in Canes Venatici, Coma And Virgo.  Managed to pick up M63 - The Sunflower Galaxy, NGC 4565 - The Needle Galaxy, M64 - The Blackeye Galaxy, M104 - The Sombrero Galaxy, NGC 4631 - The Whale Galaxy, NGC 4559, M84 and M86 from Markarians Chain, The Leo Triplet and M87 - Virgo A, plus  a whole host of other NGCs.  Not much in the way of detail, (mainly due to variable conditions), they pretty much all lived up to their names as ‘faint fuzzies’, but nonetheless a most rewarding couple of hours.  The Sphinx performed spectacularly, with each goto resulting in the target well within the FOV.  The most gratifying aspect of the evening was the integration of the Avalon X-Guider into the ensemble, getting the main scope and finder dialled in is just so much easier now.  Also the laser pointer performed its function perfectly as well, that being to improve efficiency of initial star alignment.  All in all a most enjoyable two hours or so of observing.

      Hi everyone, not sure if this is the correct forum for this thread but thought it was close enough to topic 🙂  
      In prep for my Pulsar Obsy build a couple of months from now I’m looking to get ahead of software requirements for the dome.  Can anybody provide advice on a decent ‘Skinny’ software stack for mount and dome control.  Observing has been simple for me thus far, only need to worry about mount control.  However,  I got to thinking about how clumsy and inefficient things would be if goto commands were two separate unrelated actions one for mount control from my chosen planetarium software SkySafari, and then having to reach over and key in the Azimuth setting for dome position.   As far as I know there is no dome control interface from SkySafari, so it looks like this will be achieved via an RDP session into my Intel NUC and thence to the dome controller.   No big deal I guess this will just join my Atik Horizon control Software.  What is my best solution for joint mount and dome control?
      Kind Regards
      Paul.

      Hi all,
      As i am soon to be the proud owner of a Vixen Polarie star tracker i am looking for some advice from the experts here on SGL with regards to widefield imaging with the Vixen Polarie.
      I will initially be using it with a modified Canon 600D so am looking for advice on which lens would be best suited to use with it, I have already been pointed in the direction of the Samyang 135mm which by all accounts is a pretty good contender, so aside from that particular lens what other/s would you recommend that are Canon fitting,
      Thanks in advance 🙂

      Hi I've got an 8" dobsonian and I just got a dslr to connect to it. Obviously there's no tracking so what kind of things can I capture. Will I be able to do dso and planets?
      Thanks
