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

Nice image. Perfectly shaped star, especially for 2800mm fl. Thanks, Jason.
