After looking at the initial code,

Considerable code changes in various areas since the initial release.

Sorry Jason I didn't mean to misquote you. I was reading between the lines. Or trying too. I thought you mentioned having the Starlock on the saddle introduced flexure that was addressed by moving the Starlock onto the top of the OTA. It was that to which I was referring.

However as has been discussed quite a bit, the focal length of the guide scope vs. the OTA are at such a disparity that the guiding accuracy is limited.

---------------

Jason Ware straight out said that there was a lot of flexure in the system

Not if the sensor on the guide scope has very fine pixels.

I didn't say there was a lot of flexure in the system. I said. I believe there was some mirror movement. The rest of the system looks very good.

As for the mirror movement, I am currently working with a 14" where this has been addressed. Its looking really good.

Yep, seen some of it

but none of what i have seen so far, ( up to 1.0k ), tells me they have changed all the code to allow StarLock to talk "DIRECTLY" to the motors, which is what i was addressing.
To do that would require a rewrite of Starlocks comms and a complete replacement of the electronics inside the LX850 ( as the LX800 used basically the same cards as the LX200s and hence the motor cards are controlled by the main motherboard ).
I hardly think that change will have happened in the timeframe given.
If you send me a copy of the latest rom, i can check it out fairly quickly.
If not, it wont take long to confirm once the scopes are out in the wild.

Good point, thanks. I did move it to the tube. I think it made a bit of difference but I think the majority of the movement I was seeing was mirror. The guys at the factory have compared it in both places and they have not seen much of a difference.

Actually the FWHM is a bit lower than shown. Just realized I forgot to set the image scale for the 14" and check the "arc seconds" box so it was reading in pixels. I think that is just over 2" if I did the math right.

We have already been through version X. It had a problem with Uranus. Just kidding.

I haven't tested that but I believe the software keeps track of the planet locations.

I saw the new code to exclude the bright planets and moon in 1.0k, but if i read the code correctly, it had used Earths data for Venus, hence my suspicion of if the system worked properly near Venus.
All will come out in the wash
