My camera + OAG is the old workhorse: STF8300 and OAG8300 + ST-i guide camera. Not sure that you can get the above setup from Diffraction Limited anymore. cytan

I'm using the SBD12+SBDAPB and the 14inch Losmandy plate with my AP130GT. See attached photo. cytan

Hi Marj, I got a piece of non-conductive foam that had the right thickness to compress the board down when the cover is screwed back on. See photo. Interestingly, I see flux residue on the pins of the

Thanks for reminding me about the black foam being slightly conductive. Forgot about that :) cytan Be careful that you don't use something that's conductive, or you may have infinite problems. Electro

Thanks Marj! Pizza is definitely well deserved. I didn't see any foam when I took the cover apart. It's easy for me to add some black electronic foam to hold it in place. cytan

Hi Roland, That was the problem! I pushed on the main board and could feel the board going back into its socket. It moved quite a bit. I have no idea why it would have moved out of its socket because

I pushed on it. But it didn't feel loose. But after doing that, the LED lit. I'll work on it later this evening ... Thanks! cytan

You mean this board that I put a rectangle around it?

It's one big fat zero right now. CP4 LED is off, and after I connect the ethernet cable, nothing blinks on the ethernet port (unlike the first part of last night). I opened up the plug for DEC and eve

Do you remember whether your CP4 LED lit up? Anyway, it was a very weird night. After powering up, with the CP4 LED lit up, I wasn't able to talk to the CP4 with USB. I changed USB cables and used my

Hi Rolando, I'll call George on Tuesday. In case, he does read posts on the long weekend, I did the following this morning: (1) Checked that the PS is spitting out 13.8V. (2) When connected the PS to

Any suggestions as to what to test? I thought I had at least checked that some of the USB cabling, PS, computer were ok with the Mach1. cytan Sent from Yahoo Mail for iPad

Hi guys, I think my AP1100 CP4 died this evening. The first symptom was that my CP4 wasn't recognized with the USB connection. But I could talk to it via TCPIP (my backup). But APCC couldn't move the

Thanks for the warning about WD40. That's another reason to ask here because I'm really not mechanically inclined. cytan

Thanks for the info Roland. I guess I'll try this: https://www.homedepot.com/p/Prime-Line-2-75-oz-Dry-Film-Lubricant-RZ-50-2AB12/100300231?keyword=dry+film+lubricant&semanticToken=301100401122000000_2

Hi guys, So, after a few trepidatious taps with a mallet and a long T-handle allen wrench, I got off the adapter. Whew :) I've always wanted to know this: Is it ok to put some grease or WD40 to the th

Hi Roland, So I don't need to disengage the clutches or the gear box? I can definitely tap with the best of 'em :) cytan

Hi guys, I just received the new AP1100 CW shaft adapter with SS insert and I want to replace the existing one without the SS insert. I removed the CW shaft and my telescope and then in the park 3 pos

Hi Marj Thanks! I'm really looking forward to using these shaft adapters. I always worry about cross threading when I install the CW shaft on my AP1100. I've put in my order for the AP1100 adapter and
