Thanks for the sample, Jason.

I have several questions.

What was the sub length on that shot?
Was this again without the f/5 reducer?
Was this with your make-shift mirror lock or without?
Is Meade still trying to reduce mirror deflection?
Is the OTA you are using with any improvements Meade has already made to it?

Awesome Rosette, Jason.

I think that shot looks great, I couldn't even come close to getting anything like that stars look round impressive nice work.

Accusations of falsifying data will get an emotional repsponse.

Last night was a little better seeing, not great, around 2" best focus. I also got a chance to try the latest firmware. This included some PEC updates and Starlock initialization updates.

Here is a 5.5 hour HA Rosette shot. The starlock tracking is essentially perfect. For the pixel peepers, you will see a very slight (about 1 pixel which is .77 arc seconds) diagonal elongation at the center of the frame. I believe this is the last bit of differential flexure. Not bad for a Cat.

Keep in mind this is an undprocessed image. Just combined then a slight stretch in PS. Many masterpieces you see on the net are deconvolved, dark overlay trailing reduced, etc.

That's actually pretty impressive. I would 't have expected so little trailing at 2,400mm focal length using a guide scope. Nice!

None of the images I have seen with lx800 and a large sct show any benefit of the greater aperture and I think better results would be achievable with a well-focused 130mm refractor - and it would be much easier to operate. Frank


And the latest posted image is no exception. Stars are round but bigger in size (arcsec) than what the optics allows.
Stacking of flexure affected images can result in round stars but they will be large.
To see flexure and image quality, un-processed individual raw subs would be best.

10 minute subs, none rejected. Prime focus no reducer. Native PE is about 16", corrected to 5-6 over six+ minutes. That is trained with PEMPro through ASCOM, should be even better with
direct input once we get the numbers to the PEMPro developers. But that is in the noise. Starlock can guide that out. Only place it may help is on the rare occasion when there are very few guide stars. Starlock has to increase integration times to a few seconds and we sometimes see a bit of trailing. I haven't seen this often with the latest code, better sensitivity....and I am in light pollution hell as well.

Jasson,

Regardless of what system you use. I am very impressed. Did you get any feedback on the manufacturer when they will be letting these loose in the wild? Many people are on fire waiting for their mounts to get shipped back to them. Your photos are probably not making it any easier for them as they go green with envy!

Jason, this is pure AstroPorn! :bow:
Very nice!
For those of us who don't have countless hours of time to spend on learning how to assemble and operate an astrophotography system, the Meade LX800 will be perfect. I'm glad to see that it's coming along nicely.

Jason once you give the mount your blessing can they pay you to write (or probably, RE-write) their instruction manual?

Jason,

You haven't been accused of falsifying data; you're being asked to make the beta test harsh enough to ensure the LX 800 coming out of it is a clear success.

Meade needs help in that area, or else the original beta program would have successfully wrung out the mount and the initial rollout wouldn't have resulted in a recall.

What this is all about is the objective can't just be to produce pretty pictures- you're obviously doing well at dialing in your personal technique on that score.

The comments I and others are making are about setting that objective aside and doing the types of imaging required to force the mount's tracking to meet its specification. That's exactly what a half dozen CN owners will attempt when they get their LX 800s back, and will be posting the results here.

So, if your beta test leaves anything unresolved, it'll be filling this forum a month after re-delivery. So, personal feelings are irrelevant- the delivered mounts have a variety of different OTAs waiting and advanced imagers who really do very long exposures ready to try that out.

-Rich
