Autoguiding on a NexStar Evolution SCT

Recommended Posts

Has anyone been successful at autoguiding a Celestron NexStar Evolution SCT? It doesn't seem to have an autoguiding connection on the mount. Some articles mention a way to do this through a PC, but fail to go into further detail.

I'm aware that a wedge is needed for this, I just can't seem to find anyone that actually did autoguiding on this type of scope...

Anyone? There are plenty of these wedges for sale, has anyone used one?

Found this on cloudy nights ...

Seems doable

'have an Evolution and you can autoguide them via ascom with the normal computer connection - and it should even work wirelessly.

But almost all autoguide software would need to use PulseGuide commands - and those are only enabled by ascom when the mount is on a wedge and in equatorial tracking mode - rather than alt-azimuth.

So yes - effectively you do need a wedge to autoguide, but you don't need a special guiding port. You just need computer control of the mount via ascom.'

      Hi everyone,
      I would like to use my QHY5L-II with my OAG. However, it seems like even at 2x Binning its not able to see stars. I've used Dark library, but no use even then
      Any help will be appreciated.

      Hello everybody on this community, very happy I recently joined stargazers lounge.com
      Last November I was able to modify my EQ5 mount via shoestring astronomy GPUSB (ST4 mount-USB laptop, my guiding camera is connected to the laptop by USB and PHD2 as guiding software) so I can autoguide it for long periods 6 minutes and more, I was really happy that this project was achieved and now I can get more details out of deep sky objects.
      My question is how can I go GOTO with this set up, trying to find objects to image is really time demanding without GOTO, and my goal is to take advantage of time to get those photons.
      I installed already ASCOM but I didn't connect with the USB connection (I think only work with serials cable)
      Thanks in advance for your valuable comments

      I have recently bought a Orion Starshoot Autoguider. I downloaded phd 2, eqmod and ascom stuff. After a small research I found out my mount (exos 2 gt) doesn't support computer acces without firmware upgrade and fancy cables but I have the st4 port so it shouldn't be a problem. In phd I choose camera as Starshoot Autoguider and mount On-Camera. Aux mount and AO are both none. My wiring is one cable to pc from camera and another to st4 port from camera. When I started looping I selected the star with no problem. I choosed the one star alignment option from my hand controller and after centering the Archturus in the middle of view I pressed ok and it was successfull. I started guiding and after a while I get the error: RA calibration failed star didn't move enough.

      I connect my mount to PHD2 using ASCOM and most nights I have the error "Star did not move enough" as well as "Suspicious blah blah, axis may not be perpendicular". This does not happen when I connect the mount via ST4 cable. I read somewhere that I can do a Calibration Sanity Check in PHD2. I am however unable to find that function in the software. Is it some pop up feature or does it have a location in the settings/brain icon?
      Any help will be highly appreciated.

      I have recently purchased an Orion Mini guide scope and I'm keen to start autoguiding using my Altair GPCAM2 224. However, I have a MacBook and it's not playing ball. I've managed to get BETA versions of Atair Cam and PHD2 drivers on my Mac but the frame rate on Altair capture is horrendous and PHD2 doesn't recognise the camera. Therefore I'm resigned to having to shell out on a windows based laptop. I'm looking to the second hand market at the moment but all I want is the minimum specs I need to capture. I will use the Mac to process images.
      Altair states minimum requirements are :
      Windows PC Hardware Requirements: Minimum CPU: Equal to Intel Core2 2.8GHz or Higher Minimum Memory: 2GB or More USB port: USB2.0 High-speed Port  
      It doesn't say if this is IntelCore2 single, duo or quad. I'm presuming single here. Even still is that the minimum for just capturing data? What are others using. I'm really reluctant to start shelling out another £100+ on a used laptop just for autoguiding.
      Chris
