f the worms are fully in mesh, then it's possible that the end-play not is loose.
It should say end play nut.

Thanks Roland. I do have play in the axis, but any tighter and it stalls. 
If the worms are fully in mesh, then it's possible that the end-play not is loose. This is the adjustable nut on the end of the worm gear that holds it in place. If it's loose, then the worm gear is able to move back and forth sideways as you push on the scope or counterweight shaft.

By the way, having backlash in RA has zero effect on guiding. In Dec you want to have little or no backlash, because during guiding you will be reversing the axis as the guide software tries to keep the star on the centerline. If there is too much backlash delay, it takes a long time for the axis to react during a reversal.

I'll remove the housing and take a look.

It's a fun project!

Ps- will any high end silicone grease with good temperature ratings be ok?  I have a high end silicone vacuume grease on hand. Otherwise I can get the 105 grease specified in the service guide you made. 

Thanks and happy 4th!

It wants someone to migrate every piece a gear they have ever used. So for those that have some really old images (even those moved to staging) it is asking you to migrate tons of gear via a very slow and clunky interface.

Depends on what "a lot" is.  The worst part is early.  I set up just before sunset - earlier and it heats up too much from the sun, later and the mosquitos get too much blood.  This means it goes from a 74F house to maybe 85F ambient, then just as the glass is heating the ambient falls back to around 75F.  By 10pm+/- ambient stops changing fast and at a guess an hour or so later the OTA is probably more stable. Maybe, I do not know for sure. Maybe the vents on the edge help. 

I've tried refocusing based on temperature with zero success, really negative success.  Tracking trend lines they would reverse from one night to the next (probably related to what exact thing I measure).  Perhaps if there was a temp probe on the mirror back.  Now I focus every 45 minutes whether I need to or not, with a safety net checking HFR increase.  Works well.  I probably could change that to 45 minutes for the first few hours, then rarely, but that is inconvenient to program in NINA so I just keep going every 45 minutes. 

I added a Litecrawler.  While it has a lot of benefits, focusing faster (I'd say 50-60% of prior total time) makes focusing more often less costly.  Plus I can now change filters (with filter offsets) while guiding and not have to stop/start due to image shift. 

So short version is: Focus fast, focus often, and I don't think about it too hard.  And Nite/Litecrawlers are great!

Full size here:  https://www.astrobin.com/92m59x/

All credit to the AP1100AE for the round stars of course.

I love getting data across all filters, it shows so much hidden detail viewed separately; I absolutely HATE trying to turn it into images. Picking colors, blending colors just drives me insane.  After a while I become a sort of color blind zombie just trying pallets at random.  This was after taking a day off and changing approaches. 

There is about 18 hours of data at 2800mm/F10 through all 7 filters (no luminance).  The stars are RGB only, the red on the bright part of the nebula comes mostly from the RGB (blended after stretching with square of value), and the halo and blue/cyan mostly from the NB colors, which were combined in a ForaxX type formula.  I first tried blending Red + Sii, Green + Ha, etc. but that did not work well, so I built the BB and NB images separately and combined.  I'm still not happy with the powder blue color but making it darker or more saturated just seemed to make it worse.   I'm even more unhappy with the dark part of the background which is blotchy from combing narrow and broad band backgrounds, but attempts to fix it made star replacement look even more strange. 

As I said, criticism and suggestions more than welcome, here or on Astrobin.

Re: Things NOT to do

Geof Lewis
 

Hi all,
This is an interesting thread. I also had some difficulties with the migration tool, so raised a support ticket with Salvatore about it and he was very responsive, in fact we had several email exchanges about it over the past 2 days as I did find it very confusing. However, with his help I have been able to migrate most of my gear, including creating some new gear items and editing some for a more accurate description.
I did make a couple of suggestions, which Salvatore indicated he may include, e.g. I also appear to have used Chroma LRGB somewhere, but have no clue on which images, so am not able to migrate it. It would be good if there was some way to search for the offending images, as I won't just pick a random Chroma L as that would be equally inaccurate.
This is certainly a fairly tedious process, but IMHO the quality of names that different people h have used definitely needed to be cleaned up, so I'm happy to do my bit.
Regards,

Geof

Re: My AP1600AE has developed a habit of rocking back and forth in RA while guiding #Absolute_Encoders

Roland Christen
 

We have new software that can be downloaded for both the CP4 and CP5 that addresses some of these issues. The problem is that for some heavy loads the mount needs more internal dampening in the control loop than what was originally set at the factory. It's a matter of how much moment of inertia the mount sees on the two axes. Very high inertia can lead to instability. And it isn't just weight, rather it is weight at a distance from the axis. Therefore a 50lb scope that is 20 inches in diameter will have much higher inertia that a 50lb scope with 10" diameter.

Tomorrow when everyone is back here in the office I will have Mike contact those who have seen this effect and we can have you run a few simple tests to see what software settings you have in your controllers. Then we can make some recommendations which will fix this issue for you.

Re: Ocean-side location corrosion precautions

There isn't much that can corrode. Everything is either anodized aluminum or stainless steel. That includes all the nuts and bolts. You might get flecks of rust on the counterweight shaft and counterweights because even the best stainless steel can have some inclusions. To prevent that, rub these parts with a bit of car wax.

I’ve been very fortunate to build a permanent observatory to house my setup with my AP1600GTO AE with pretty good skies. The downside is its location near the wild southern ocean with sea mists and heavy dew so I’m concerned about corrosion risks. The gear is housed inside a 3m dome and I’m operating it remotely with Voyager linked to an AAG Cloudwatcher  
Are there any suggested precautions I can take that could help guard against these risks?

Re: 400GTO

Roland Christen
 

There are two mesh points in the 400. One is the worm gear to worm wheel mesh. It sounds like you have that tight enough. You can judge that by putting slight pressure on the end of the scope in both directions to see how firm the position holds.

The other mesh is the gearbox mesh, which is not obvious , but is easily adjusted by loosening a couple of screws and gently pushing the motor spur gear into full mesh with the spur gear on the end of the worm.

Checking things like the above, it always helps to remove cover plates and to take a look at the mechanics. That way you can see how things are put together and can get a feel for how it's supposed to work. Also, there are many helpful PDF's on our website for legacy products that can give you information on how to adjust these products. If all else fails, there is always George or Howard during business hours.

Any tips or tricks on fine tuning gear mesh?  I have a lot of backlash in both ra and dec. If I mesh any tighter I get motor stall issues. I'm having some stall issues as it is and can feel significant wiggle in both axis.  

I've got a 130gtx on it. Balance is pretty darn good. 

Wondering if these symptoms are me not meshing right (and needing tips) or if it's a sign that I should do a full service. 

Ps- I have the AP mesh procedure document and followed the directions.
