Re: Pointing Model for Unguided Imaging on a C11" EdgeHD (with primary mirror locked)

Bruce Donzanti
 

Thank you all for the feedback.  I am doing OAG now and can easily get good tracking and round stars up to 5 minutes but the guiding can be finicky at times.  So, it is a thought to try but I will think about it further.  I realize the mirror is not really locked but it appears good enough to make a huge difference.  And I agree it is probably scope-dependent to a degree as to how well it will work.  

Thx again - I appreciate everyone's opinions and suggestions

That’s good news, Wayne.  We highly recommend that everyone write pertinent details on the first page of your mount manual, such as the serial number and license keys.  Just another place you can find it later if you need it.

It’s worth a try, but there is no guarantee.

 

I have an EdgeHD 8, and I have to use an OAG.  I tried “locking” the primary mirror.  The clutches on the EdgeHD scopes are not actually locks.  They are two flexible rods that can be locked with the knobs on the back of the scope.  This greatly reduces the primary mirror tilt as the scope moves, but does not completely eliminate it, since the rods are flexible.  Also, the rods don’t to anything to prevent lateral movement of the mirror, relative to the baffle tube

 

The upshot of all of this, is that at a 0.5 arc seconds per pixel, 5 minute exposures were not usable and 3 minute exposures had very noticeable elongation.  Exposures under 2 minutes were not horrible, but also not really good.  I did experiments with a guide scope, and I did experiments with going unguided (with a model and absolute encoders).  The only thing that gave me acceptable results was an OAG, which completely solved the problem.

 

Still, I have heard of others that are locking the mirror clutches and getting acceptable results, so there may be some variability between scopes.  As I said, it’s worth a try to see how your specific scope works.

I am once again re-thinking if it makes sense to attempt unguided imaging on my C11" EdgeHD where I have now locked down my primary mirror and upgraded to the Optec FastFocus system where focusing is done solely using the secondary mirror.  This should eliminate the major mirror flop/shift issues due to moving the primary mirror.  My scope is on an AP1100 in a permanent observatory but I do not have encoders.  I use a ZWO ASI2600MM Pro camera (APS-C sensor) and usually use the 0.7x focal reducer.  The question is:  Is it even worth the effort to try building a model to go unguided imaging or is a refractor still the way to go?  Guiding works ok but it can be finicky at times.

Fwiw, a bit tangential, but to the point of long FL uguided imaging…. I did a backyard test recently of a Meade 12” ACF at f6.7 (2040mm FL) (with clement focuser and robofocus) on the ach2. I didn’t build a model but just did “short” 3 minute unguided  exposures and the stars look good.

APCC PRO and Horizon Editor

Jack Huerkamp
 

I used my Theodolite App on my iPhone to get the horizon altitude every 5-10 degrees for 360 degrees of azimuth.  I created a table of the values and would like to create the horizon in APCC PRO on my laptop in the house and then somehow import it into APCC PRO on my observatory PC. I keep looking at the manual and it explains how to use the mouse to drag and create the horizon line.  What I want to do is add horizon data points one at a time and create my horizon.  So far I have been unsuccessful.

Does the mount have to be connected to APCC with my location selected to create a horizon?  It seems that should not be the case?  Or am I doing something wrong?

My 24v power supply that came with the mount died sometime today.  My system was set up in the back yard and other than shutting down the laptop, I did not power down anything else.  I just threw a cover over my scope. 

Went to use it this evening and could not connect to the mount.  Went to investigate and found that no power was getting to the mount.  LED light on power supply brick does not light up.  

I've ordered a different power supply from Amazon but I'll have to build it. I'll just re-use the wires/cables that came with the original.

That's funny. Mine also died but I was speculating that it was from the sub-zero freezes we've been having.
Contact AP, they took care of me and sent a new one.

I did order another from Amazon too as backup, since clear nights are precious here in New England and I lost out on a few in a row (isn't that always the way).
You just need something like this https://smile.amazon.com/gp/product/B07N2ZJ18D/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 to connect, assuming that you bought one with a 12 dc connector.

Re: Mach2 Slew Speed, Power, and Voltage Question #Mach2GTO

Greg McCall
 

I was more hoping by now a more specific answer was available as I've never seen a manufacturer not have an actual specification for their equipment.
Having a 24v system and not allowing for use of a 24v off the shelf battery (with charging) seems to be a poor design.
12v or 24v are usually nominal voltage based historically on a car or truck battery systems. (with an appropriate voltage range for charging and discharging batteries)
Using a mixture of batteries to get close to the voltage is just not practical. 


Re: Data base corruption

Liam,

 

If I had known that I could unplug the fiber bundles from the two LEDs, that would have definitely made battery installation easier. But since this was not an option mentioned in the AP instructions, I worked around the fiber bundles.

Jack,

 

The individual optical fibers are not mission critical, and breaking one or ten of them will not disable any important aspect of the keypad. While it is good to be careful, you would not notice if a few strands snapped when using the illuminated buttons. In addition, you can simply pop the little rubber caps off of the LED lights and move the fiber bundles freely. They have a full 180 degree range of motion. If you don’t pop the rubber caps off of the LEDs, you would end up having to weave the battery wires through two bundles of optical fibers; a task I wouldn’t wish on anybody.  

 

As the technician that works on keypad repairs every week, I used to be very very careful. Eventually I learned that they are less delicate than I thought. These days I can fly through the repairs much faster, and still have yet to break a fiber optic by accident. The most important part is to make sure that the rubber caps get back onto the LED bulbs securely.  

 

I hope this helps with the next time.

George,

 

I just wish a little more thought had gone into the design and engineering of the keypad.  Placing the battery and its connection to the PCB below all those optical fibers should have been avoided.  As a 40+ year mechanical engineer, I have seen many situations where I wish the engineer who designed systems was forced to work on them afterwards.  Like having to remove valve covers to replace spark plugs on a motor.  Or having to remove the transmission to get at the starter mounted next to the torque converter. 

 

I was worried the whole time I was working on the simple battery replacement that I would damage one of those fine optical fibers.  And then when I went to close up the keypad, the optical fibers would not lay flat and kept trying to get between the case and one of the red plastic standoffs.  I ended up getting a piece of cardboard about the size of an emery board, laying it over the optical fibers to hold them down, placing the cover over the 6 screws, starting to tighten them and then slowly sliding the cardboard out from the case. 

 

At least next time, I will know what to expect.

 

Yours truly,

 

Jack

George,

 

I guess I got lucky!  I received the replacement battery and, using the instruction downloaded from the AP website, I was able to access the battery.  I did manage to disconnect the old one, fish the wires under the fiber optics and get it plugged in.  Then when trying to secure the battery in its holder, I noticed that the connector had dislodged.  I figure that there wasno battery power for over 30 seconds, but when I got the keypad back together and tried it, it appears that the Messier and NGC databases were not lost.

 

I connected the mount to SkyTools, did a slew to the Sun and that was fine.  Then I used the keypad to go to M33 and then NGC 7814.  In each case the crosshairs moved onto the targets on the atlas, so it appears that all is fine with the keypad. 

 

I will know for sure the next time I get to use the mount.  Once the keypad battery issue was accomplished, I started removing all the scopes from the mount to tackle the regreasing of the RA and Dec gearboxes – another long overdo maintenance issue.

 

Yours truly,

 

Jack

I just replaced a keypad battery (and a cord) (and I have another keypad which will also get a new battery as soon as I get some time). 

  

It seemed the DB did not get lost when I swapped the battery... tho i might not have checked the Messier objects.   

How long will the keypad memory persist without a battery?

Just had this happen to me as well.  

 

The custom battery is a bit expensive but once in every 10 to 12 years ain't too bad.  Removal and installation of the battery requires care but is straightforward as it reloading the database, though it can take a while.

 

I also went to the .19 firmware version.  Jury is still out on that one.
