This baseline procedure was put together by one of the responders on the PHD2 forum.

"A good way to ensure a solid guiding baseline is to follow the baseline guiding steps, link below. I realize you may have done many of these steps already, but doing them as described gives you (and us) a clean calibration, GA run, and guidelog from which we can further look at your results
 
 
if not, at least do a fresh calibration near the meridian and celestial equator intersection (dec close to 0) followed by a guiding assistant run and 15-30 minutes of uninterrupted guiding"

I added a GTO 1100 with CP4 to my existing GTO 900 CP3. One of the reasons I did was because of the Wireless. Sadly the wireless on the CP4 is problematic. I and others have issues of it dropping connections and than having a hard time reconnecting. I was one of the early owners of the CP4 and although there have been a few firmware updates on both the CP4 and hand controller, nothing has corrected the issue. I run Sky Safari Pro latest versions.  I finally had to go with a SKYFi latest unit which does work flawlessly with Sky Safari Pro. I run with a couple of Samsung Android devices....tablet and cell phone. I know AP has been trying to figure out what the issue is but not having any luck. Those runnng Apple devices may have different experiences. 
In short if you are happy with the CP3, and want wireless the SkyFi unit does work great and you won't need to upgrade to the CP4....especially for visual.

I can't figure out why SkyFi works so well and AP doesn't. Perhaps it is the wifi module in the control box itself.

Best for you to go on the PHD group. They have very helpful people there that understand the program far beyond my meager knowledge.

Hello, can you tell me if there are recommended aggressiveness settings for the ap1100 mount when using phd2? I presently don’t have a problem but was wondering if AP has a recommendation? Thanks Leon F.

Re: SkySafari Pro 6 with GTOCP3

Dominique Durand
 

Hello,
I confirm that the combination Mach1CP3 / SKYFi3 / standard RS232-USB converter / Safari 5 plus works well on my Android Cell phone. However, I still have the keyboard plugged in and in particular to put in park3 at the end of the session. I turn on the frame which automatically unpaired, I connect with Skysafari which synchronizes with the frame.
I also tested the connection with a Mach1 CP4 and I also noticed disconnections, the reconnection being quick to do.
By cons I have a problem with my new mach2 CP5. The connection is done well but not the synchronization if I have not previously turned on the mount with connection to APCC (or to the driver). I can move the mount with the arrow buttons, but the indication of positioning in the sky is not the right one and the GOTO does not work.
Is it the absence of the keypad?

Dominique

Thanks Woody,

I have a couple adapters, one that is several years old and one recently purchased.  Neither has the FTDI chipset, however, so that is well worth trying.  Much appreciated advice.

Adam


Re: SkySafari Pro 6 with GTOCP3

Woody Schlom
 

Adam,

 

I’m not a Mac person, so can’t help you there.  But I have successfully controlled my Mach1 CP3 using SkySafari-5 Pro and SkySafari-6 Pro using either a SkyBT (serial to Bluetooth – a.k.a. RN-270) or SkyFi-III (serial or USB to WiFi).  All work fine.

 

If you’re using a serial to USB adapter on your Mac, which one do you have?  I realize that AP used to recommend the KeySpan HS-19, but I retired mine many years ago in favor of either a genuine FTDI adapter, or another brand containing the FTDI chip.  For some reason, FTDI “gets it” and their chip just plain works – with everything.

Hi All,

Anyone using SkySafari Pro 5/6 to control a GTOCP3 via USB-serial adapter on a Mac?  I can't seem to get the scope to connect, though I recall this working a few years back when I tried on an earlier macOS and possibly before I updated the firmware in the CP3 to V2.  Probably I'm missing something simple so let me know.  I can provide the connection log if that helps.  

Notwithstanding the above, I am also considering upgrading to a CP4 for the wireless and USB connectivity, so interested in hearing the experiences of anyone using SkySafari Pro on a Mac with the CP4.  I am a visual observer so looking for a simple observatory/mount control option and SkySafari Pro seems like it could be a good solution for me.  

Thanks!  Adam 


Re: SkySafari Pro 6 with GTOCP3

Thanks Robert, have you used the SkyFi with both the CP3 and CP4?   I see that the device has a physical RS232 plug, so that would remove one possible source of problem from my equation (usb-serials adapter).   Adam

Re: What's the effect of imaging through jet stream?

Cheng-Yang Tan
 

Yes, both conditions can destroy image quality. For the heat from the pavement, at least from my experience, there's enough cool down time for the pavement from installation to the first image that it really doesn't matter. Hot roofs on the other hand is a different story. I try not to image above the roofline which is south of me. I try to image as high in the sky as possible and that's works well. That's the travails of imaging in suburbia.

I have seen about every geometric shape possible with out of focus stars during a FocusMax run with the 17", worse when the seeing is poor.  According to my seeing monitor, I tend to run around 2" on average, with some periods of significantly better, 1.5" or less and sometimes 3" plus, on the same night.  It can be reasonable right after sunset for about 30 minutes, and can be reasonable before dawn-sometimes.  I have done what is possible around and in the observatory to minimize heat effects (I am in SE AZ), but I can't control the upper atmosphere.

cytan,

I generally have poor local seeing, but I am amazed at the variation that is possible. On good nights, guiding with my Mach1 (last generation) is around 0.3-0.4 arc seconds and the resulting HFD of the subframes is in the 2-3 range. On bad nights, particularly when the jet stream is a factor, guiding is 1.5 arc seconds or worse and the HFD is much higher. On the worst night in memory, my HFD was 10+! I thought there was something wrong with my optics—the stars looked like giant snowballs and refocusing did not improve them. But a couple of nights later, guiding and image quality had returned to normal. So in my experience the jet stream can significantly degrade both guiding and image quality.

Glenn


Re: What's the effect of imaging through jet stream?

Hi Glenn,
  Good to know that my earlier problem was also observed by you. Unfortunately, l am not completely convinced because my setup is torn down and reinstalled each evening. Although I always set up close to the same spot on the sidewalk, and I try to be consistent setting up, I really cannot guarantee that each install, PA is identical.
   Everything went smoothly last night though despite the wind. Who knows what the real cause is if it’s not the jet stream the previous night.

Re: Mach2 Unguided testing continues

Dean Jacobsen
 

I have been using the keypad for the entire 17 years that I have been using AP mounts... except for now while I am waiting for the new version. It is handy and it always works.  If I am imaging an object with a Messier, NGC or IC designation, then I will just usually enter it in the keypad directly.  If I am going to a Barnard, LDN, VdB catalog object then I have to use TheSkyX. 

On occasion when I do put an eyepiece in the telescope it is fun to go though some of the provided "tours". 

The new abilities for the CP4 and CP5 controller will make it even more useful to me.
