Update on Astrotortilla - I've now got it working and it's fantastic. It was worth all of the angst trying to get it operating as I now get every object bang in the very small field of view that a Atik 314L+ has. The problem was I didn't download both index files as the instructions tell you that you don't need both unless you are using a 3 deg or more field of view. My advice is download everything and if you want to isolate the files you don't need you can move them to a separate file so it doesn't slow the system down while plate solving. To be honest I just leave everything where it is as it doesn't take much longer to plate solve using all the files. The other problem was using the exact fov for each combination of camera and scope - don't do this as you spend days trying to figure out why it won't plate solve. Use at least 50% more at each end of the scale eg. if smallest fov of 5mins use 2.5mins and if largest fov 1deg use 1.5deg.

Thanks for that, but the blog has been removed. Do you know of anyother links?

Thanks for your quick response. I've just checked the log viewer and it hasn't kept any of the file details, but hopefully it should be clear tomorrow night and when I set it away again I'll put the log onto here.

I have been very busy beavering away in my new obsy so I haven't had much time to come onto to Stargazers Lounge, but when I need help I know somebody on SGL has already encountered the same problems so I'm hoping to be helped with an Idiot's guide to Astrotortilla. I don't think it's the setup as I have downloaded all of the index files I need to run it, I also have setup my camera/telescope combination and everything is running okay - except it won't platesolve. I even gave it a photo of M51, used telescope simulator and even upped the search area to 180deg - still nothing. Can anybody help me

I think it depends on the size of the aperture as to how they build it, but for me they used a fixed rail system onto the garage roof. The total cost of the hatch, including electrics was £4,400. If you just want a manual opening then I think that is about £2,000. To be honest I went for the electric motor because I have problems with arthritis and I thought I might have a problem with the weight of the sliding hatch and it being difficult to move - far from it, it is so finely balanced it moves very easily by hand. I think if I had of known that I would have just gone for the manual opening. I also looked at a conventional observatory dome, but that worked out at £3,600 for the motorised version - and again the problem with that was because of my location on the coast road the World and his wife passes by so security was an issue. I opted for the flat hatch as it doesn't announce to the World "come take my kit" - also some bright spark might have thought I'd opened Mosque

It is good quality kit Mike. Mine is 1300 x 1300 - that's 4ft square and the biggest my garage could take, but you can get them to make you any size you want.

The opening is constructed by a company called Surespan in the Midlands. I had to do a lot of research before I ordered it as I couldn't find anyone to make it for me - fortunately, this company specialize in opening hatches. The reason I decided not to go for the normal wooden sliding roof was incase of leaks, maybe not straight away but over a period of time - I think for the extra cost I have peace of mind and that is priceless. The electric motor is really useful as it's a simple open/close switch on the wall and can be disabled incase of power failure. The hatch opens easily without the motor, so that's always an option if you wanted to keep costs down. If you have any more questions let me know by message as I'm not sure if the moderators might restrict this posting. Good luck with your project

The pier is a steel hollow box metal construction - an off cut from a friend. The base is welded on and bolted into the cement floor with a raised wooden floor covering so there's no danger of tripping over it. The mount head is attached to the pier by welding. I've spent most of the day getting the computer setup to allow remote control, using Eqmod, phd guiding, carte ciel (sky map), and auto focusser. Finally all tested and working - just need clear skies now

Well I haven't been on SGL for quite awhile as I have been a little preoccupied - to say the least I finally, today, have my new observatory with electronic sliding hatch and recently purchased SW 200PDS with HEQ5 mount head working. It's been a bit of a nightmare to get everything together, but I can't wait for clear skies to be able to start photographing again . We went to Normandy last week on holiday and stayed in a Gite in the countryside and the dark skies were amazing. I managed to photograph the Ring Nebula, but haven't worked on it yet so I'll be adding it to my Gallery with some new material from the 200. I've added some photo's of the obsy and realise they show a limited view from the hatch, but as I'm on the North East coast the rotation of the sky means I will be able to see everything up to and including the meridan. One smiley happy person signing off.

Hi Michael I think these are very good even if you did take them in Jpeg. Don't forget to change your camera to Raw next time lol.

Just discovered that NASA is broadcasting live signals from the ISS for about 6 hours today. That's around the World 4 times whilst they are working up there - incredible. Today is the second of 3 space walks. They are changing the way spaceships dock with the ISS incase there is ever a need for quick evacuation. At the moment it's done with the robotic arm from the cargo deck - they are installing something that allows cargo flights etc to fly in and dock directly freeing up the cargo bay.
