Dome Slaving

Recommended Posts

Hi,

I'm after some advice on dome slaving.  I have a Pulsar 2.2 metre with the dome rotation kit (and two equipment bays) arriving at the end of November and I'd like to slave it to the hand controller rather than buy Maxim DL, SGP etc.

Is this possible?  My mount is a CGX-L with the standard handset.  I use SharpCap Pro to capture images and I am not looking to change my setup drastically nor spend anymore money at this point given what the observatory has cost me.

Thanks in advance!

Adam

Does sharp cap control the scope through ascom ? Replace that driver with POTH and chain the original driver and dome driver from POTH to get to your desired result.

No I don't think it has the ability to control the scope ?  unless I've missed something.  Don't want to stop using it as I've only recently got it set up the way I want for taking decent pictures!

I think that the slaving would have to be via a computer.  If you are in the dome and not using a computer then aligning the dome by the buttons on the rotation drive won't be much of an effort. 

Celestron has a downloadable computer control programme CPWI that connects via the handset and there appear to be ASCOM drivers for that.  ASCOM lists Celestron drivers and Pulsar says "The supplied Pulsar Observatories software package allows full control of the observatory from a computer, and includes  an ASCOM driver for use with third party software, i.e. Maxim DL, to allow full synchronisation with your telescope."  I presume they mean 'e.g.' rather than "i.e." so that you wouldn't have to have MaximDL.  If so then POTH in conjunction with CPWI and the ASCOM drivers should allow slaving of Dome to Mount.  POTH is part of the ASCOM platform.

I don't use SharpCap but I can't see that it has a GoTo feature anyway; the guiding feature wouldn't in itself need slaving.  I would imagine that you could simultaneously use SharpCap as now.    Certainly worth a try once you have the dome up and running.

You would certainly need to use an ASCOM driver for your mount and control your mount via a computer but you don't need anything more than a planetarium program like the free Cartes du Ciel and POTH. This is essentially what I use to control my Pulsar dome and it works faultlessly.

Yeah - wot he said. 

Tell us more about what controls your scope  - do you have ascom installed ?

      I have a steel pier for sale. This was purchased along with a pulsar dome and believe it is an older Pulsar model. The pier sat in a yard, exposed to the elements for a few years before I purchased it so there is some surface rust and flaking paint but will clean up nicely.  £250 and buyer will need to collect from Suffolk.

      Hi,
      I need to lift off the dome of my 2.2 metre Pulsar observatory so I can smooth out the joints between the 4 sections. They are causing problems when the dome is rotated. When I bought the dome it was installed by Pulsar so I have no experience of lifting the dome on or off the walls. My plan is to use 4 Acrow props to do the lifting so I can do it as a one man operation. I assume that it is best to place the props outside the dome and lift using the edge of the dome. Can I ask anyone with experience of these Pulsar domes if this is the right way and are there any snags?
      Thanks, Hugh

      I and my girlfriend has come home from a one week travel at Malta, a small island in the Medeterranien Sea. About a mount before we go I came in contact with an amateur astronomer down there, Maurice. He invited me and my girfriend to visit him and his DIY built observatory.
      The observatory is built on top of his house and it has a real dome.
      If you find it interesting to read about it I have done a small report from our visit at the Malta observatory with photos:

      The Raven and the Owl observatory, Malta.
      After this visit it's hard to understand why we stay in Sweden where we live, when it's dark it's also very cold. We often have from -20 degrees to 0 degrees Celcius temperatures. Now adays we don't have many clear nights either.

      Hi guys!
      I thought I'd pass on this link to a blog I am constructing. I intend to detail and illustrate all the steps involved in the construction of a 2.2m square dome observatory from its conception to it's complete outfitting. I am an amateur astronomer and most of the stuff I used in the making of the dome, apart from the actual construction materials  was from recycled stuff and bits and pieces I managed to scrounge. A lot of the outfitting electronics and gadgetry came from cheap Asian sources and the circuitry and software was again partly home grown or borrowed from other sources.
       
      Time, patience and a generous helping of youtube videos and forums like this one are a must if one gets stuck but thankfully one will always find the answers if one digs deep enough.
       
      Anyways ..here it is for any of you who want to browse..The blog should grow  steadily as I add more and more information and pics and of course anyone interested is welcome to drop me a line on this forum or by email.
       
      There is a lot of ground to cover and so it might take me a while to finish uploading it all ..but after all...hey ...it took me a year and a half to finish!

      Welcome to The Raven and the Owl Observatory ... a home-made little portal to the stars...

      I have a large (maybe 4 metres, 12 feet in diameter) metal dome which is in need of some refurbishment. Does anyone have any particular advice about what to cover the interior with? Previously there was some polystyrene panels  fixed up with wallpaper glue which over time have broken off and land on my optics and equipment, something I'm not very happy about. Take a look a the video or pictures in the instagram for what has happened over time (https://www.instagram.com/rhulobservatory)
      Is there any particular need to cover the interior at all? 
      Thanks,
      Stewart
