There is an option to add 2 Gurley encoders on the Mesu and it still will be within budget. De Sitech controller is fully remote controllable. Has an option to model the sky, also fully automatic (scripted)

You can use the Sitech controller without a controller (just point and track), with an ArgoNavis or a PC.

Hi Jjongmans, so why did you buy a ddm60 if the mesu is so good :grin:

Joking aside, i just don't like the whole......."well you can add this controller or add these encoders" to make it better. I don't want to have to modify a mount or alter it in any way, i just want it to take it out of the box, and it's just works without any need to alter it, and for that i'm willing to pay an extra £1000 over the cost of the mesu.

I'm hoping Tim will take the hint and do a full review of his GM1000HPS, and just in case you missed it Tim.........(HINT GM1000HPS REVIEW HINT) :grin:

I will do a proper review, but I am not going to do it without using the mount properly over a period of time. These days reviews are often quoted on sites all over the place and are taken as a basis for ordering equipment, so I am keen to have proper experience to talk about.

For now let's just say, am I pleased with the mount which cost twice as much as the car I currently drive? And the answer is yes.

For me the biggest change was going from the awesome simplicity and ease of use of EQmod, to a more powerful system with a less user friendly GUI. Per is planning his own driver and system in time and hopefully that will be more click and pointy.
That said, after one night using the new interface through the virtual handset software it all made a lot more sense and is now almost second nature.

The biggest test will come with my long exposures on my long focal length setup.

Cheers

Tim

Because the ASA has the best tracking performance; 0.2-0.4" over 20 min (and probably longer) unguided subs :)

When I set my mount up, I took a few pics, although I haven't got enough counterweights yet to do it properly, so I improvised.

The first 10 minute sub (1960mm fl) show some trailing, the second sub after a bit of refinement showed less, this picture was about an hour after I started and was 30 minutes. It is far from perfect, but this is less than two hours after taking the mount on for the first time in effect. Thought you might be interested.

There is no way I'd have considered dismantling my obsy to take a mount to a star party etc, but this one is designed to be portable (it is heavy) and comes with little bags for everything, even the mount head.

Single sub 1800 secs 460ex binned 2x2 C11 EdgeHD +0.7 reducer (1957mm). Unguided.

Right, sorry about that.....need more sleep.....

The picture is 30 minutes, not 20. As mentioned, its far from perfect, but not bad for out of the box :)

Per, at this point there was 5-7 stars in the model I think, now it has 18, but I am going to clear it and do it all again once I have the GPS and final counterweight.

Cheers

IIRC that's about 0.98 arcsec/pixel which was pushing it on a murky night in the UK. (in fact its always pushing it on any night in the uk :D )

Yes, I know the problem, I'm living in The Netherlands, I reduced my RC to 0.80"/px

This was my first unguided attempt with the DDM (binned 2x2, so 1.6"/px) with clouds rolling in...

I'm blaming mine on a mid-life crisis and I've earned it and I'm sticking to my story............ :)


Plus, it's a lot cheaper in the long run than running off with a younger woman as seems to be the norm, so the wife will probably be grateful..................probably....... :s

Tim,

Like your style, maybe i can justify my mount by promising not run off with a younger woman....
