Hi Christopher
Just curious how you remove and reinstall the red lens? (hand controller is at the clubs Obs 1 hr away LOL) Without seeing the hand controller, but looking at the manual, it looks like you need to take the hand controller apart to remove the red filter? Not sure I want club members doing that on a routine basis, sounds like a recipe for disaster.

Christopher,

 

I didn’t realize the keys were glow-in-the-dark.  Duh!  I keep mine in the case most of the time and didn’t realize the keys could/would glow if “charged.”

 

But I am familiar with charging similar glow-in-the-dark materials with a bright UV flashlight.  And I just recently got a super bright one from Fenix that’s white or UV.  It’s the same as their white/red one, but this one’s white/UV.  And since it’s so bright, it charges glow-in-the-dark materials quickly.

 

Thanks for the tip.

 

All that said however, I mostly use either SkySafari running on a phone or tablet, or my laptop running TheSkyX to control the mount.

 

Woody

Big Guy Has a New Ride

Jeff B
 

I've been meaning to do this for a while, based upon my brief experiences with my AP900 with this OTA (TEC 200ED) and long term use of another 1200GTO doing a GREAT JOB of slinging around an 8.75" F12 achromat (which weighs about 15 pounds more with a much longer moment arm). 

So, I cheated mount and scope death one more time and did the swap out between my Titan and this 1200.  The 1200 previously provided good support for a large and heavy Parallax/Zambuto 11" F7.2 Newt.   It's always an involved process but it went well.  Next up tonight will be some stretching and an Aleve.

Dim hand controller keys #Keypad

Frank Seminaro
 

First post to the group.  Please be kind : )

I recently acquired an AP1200 CP3. Fantastic mount coming from a G11. There is no comparison.  However, the hand controller keys are very dim. So much in fact, that I sometimes need to use a flashlight. I've included a picture.  Is there anyway to fix this?

Thanks,
Frank

Is the object database located in a non-volatile memory in the newest keypad or is it the same behavior in both the "old" and "new" model ?

I do have to second about what Roland says about the basic accuracy of the 1200.  

I've a 1200 in a dome supporting an 8.75" F12 achromat with some nice Parallax rings.  When first installed, I did two daytime alignments with the sun.  I followed that up in the evening with a few SkyX/T-point models to get my polar alignment miss (very carefully the old fashioned way with a 20mm X hair eyepiece, 10 stars on each side).  After the third model, my altitude adjustment was called "excellent" and my azimuth adjustment "good enough".  But I'm a firm practitioner of going against the principle of "the bitter enemy of good is better" so I disconnected the SkyX and did a drift on a star low in the east.  After about 40 minutes, I had it down to where the star stayed put on the x-hairs at ~135X, for a good 10+ minutes (I slightly defocus the star).  

I then used the hand paddle to slew to and sync on a star close to the equator and meridian.  Now slews typically put the object within 3 or 4 arc minutes of center at the worst and typically nails the planets.  

That's pretty good in my book, especially with no model!

Ah. Since you're imaging, you can use any number of software-assisted polar alignment methods, so the RAPAS isn't really a needed upgrade then.

Yeah I would just do the maintenance items and you'll pretty much have a caught-up mount that works quite well. You can then consider something like APCC Standard or Pro once you get a V2 chip into the CP3 (or, unless you have a CP2, you will need to get a CP4 or second-hand CP3 with V2 chip to use APCC).

Ah. Since you're imaging, you can use any number of software-assisted polar alignment methods, so the RAPAS isn't really a needed upgrade then.

Yeah I would just do the maintenance items and you'll pretty much have a caught-up mount that works quite well. You can then consider something like APCC Standard or Pro once you get a V2 chip into the CP3 (or, unless you have a CP2, you will need to get a CP4 or second-hand CP3 with V2 chip to use APCC).

I use platesolving to get me where I need to be, and this has worked very well. But there are times when I need a better goto/slew position.
Since I acquired and installed APCC Pro, I created a 250 point model. I was amazed at the improvement in not just guiding but the initial gotos. It is rare now that I don't get within 10-30 arc sec of initial goto across the entire sky.

The mount is quite accurate in positional moves, but that doesn't mean that your scope is pointing where you think it should. The gearwheels themselves are accurate to a few arc seconds over the entire 360 degree rotation. What causes in-accuracy in pointing will be time errors, which affects the RA pointing, and Polar misalignment, which affects both RA and Dec pointing. Add to that the inevitable orthogonal misalignment of the telescope with respect to the mount, and you have a number of errors which accumulate. These errors affect both pointing and tracking.

So, to say the mount is inaccurate is misleading, rather it is the setup that is inaccurate. Some of these inaccuracies can be compensated with suitable software, such as APCC pro, which has sky modeling. Or you can circumvent some of these by using plate solve and doing guided imaging.

Greetings group, been away from observing for quite sometime so basically starting over. As mentioned I have an early to mid 2000 1200 gto mount, my question is what is the best upgrades that I can do to bring the mount up to 2020? Right now the mount is not accurate in it's slewing even after syncing on a known star/planet. Obviously since this is completely original and the last time I used it which was probably at least 8 yrs ago something needs to be corrected or updated. I had used it quite accurately in the past so being it is a very capable mount for my needs I want to get it back so I can start observing again.
Thanks in advance
John

Dear John,

When the CR 1632 battery died in my hand controller, I simply got a replacement at the hardware store for about $5. It was easy to change. Also, reloading the database was straightforward but took about an hour or so. The instructions for updating the software and database on the hand controller on the AP website are very detailed and easy to follow.
This advice isn't universal since there are 2 generations of keypads. The older model keypad with less memory does indeed take an off-the-shelf CR1632. The newer-generation keypad with more memory requires a special battery that has a wiring harness attached to it... not something you'll find in CVS ;) If in doubt, call Astro-Physics.

Thanks Dale I do mostly imaging and yes I will call AP and get a battery and probably do the chip as well.
