Thanks Drew, the updated version certainly shows the correct LST. Do you know whether Larry and Steve intend to upgrade PAM to take JNow into account? Richard ...
Thanks Neil and Rich: I have adopted your suggestions and now have a better understanding of how to work with the software. The only remaining problem I have...
Higher PIDs generally indicate slippage in the focuser. Are the slopes of each side different?    ...Neil www.flemingastrophotography.com Direct from...
Hi Steve I have just tested v3.4.19 with regards to the Min Alt and FMx now uses the min alt correctly. This is not so critical but when you hover over the Min...
Yes, for my "bad runs" the slopes are different on each side. It seems as if I can improve things (to some extent) by changing the load applied by the...
How does the draw tube move when when you use the manually hand controller, can you see any slippage. It's unlikely it's too tight, or you wouldn't get a...
Peter, start by loosening your Drawtube Tensioner completely first. If the problem persists then start tightening. G'Luck...joe :) "May You Go Among The...
Peter, One other things, make sure you manually focus first with the hand controller (Not using your hand) then unplug the cable from the hand controller and...
Well, I took the focuser apart and noticed that the contact patch on the focuser tube was less than ideal. It seems that only the outer edges of the focuser...
Hi all, I was running some v-curves the other day and thinking about how FMax performs focusing. My understanding is that it basically measures the FWHM at a...
Hello. I am having problems for focusing under the moon light, what can I do ? Without moon, robofocus focus in 17 seconds, nicely My average PID is 0.17 ...
Alvaro, not knowing what specific issues you're experiencing you could try several things. The first question I'd ask is what is your focus star's Flux? Here...
John, the V-Curve PID is a characterization of your imaging system and focuser's mechanical 'repeatability' performance. Preferably in good Seeing once you...
Hello John- The default setting in FMx is to average 5 HFD readings at the NearFocus Position but you can increase this if you have poor seeing. I recommend...
I removed from the files section that spreadsheet which showed where to place the RA axis to point at the JNow CP because I think I found an error in it (and I...
I have become very confused about the alignment error directions that PAM is indicating on the screen. Firstly, looking at the crosshair circle labelled UP,...
Hi Steve, Thanks for taking the time to reply - I hope you don't mind some more questions ;) I absolutely see how averaging the predicted best focus position...

Hello, This email message is a notification to let you know that a file has been uploaded to the Files area of the FMaxUG group. File :...
New (and hopefully final <G>) version of spreadsheet to calculate JNow Celestial Pole offset from the J2000 Celestial Pole. The former version had an error in...
Feel free to email me. I wish I hadn't brought this up. I worry people are spending time tying to adjust their alignment to a level that is not really needed...
Hello Joe, Withouth moon this advice "Star is too close to frame edge or is too weak" never show The average PID is 0,13 My Log 19:05:41 FocusMax Version...
Several people have emailed me about confusion as to which knob to turn to move the mount "west" or to "make the negative Az Error smaller" etc. You can try to...
Once you figure it out I used a label maker to make up some labels and put them on the mount. For Instance it says Tighten CCW West, or Tighten CW East by...
Hi all, I recently obtained an RF3 and wonder what the best settings are (step size and microstep pulse) for use with FM? The scope is a Televue Genesis and...
John, follow Neil Fleming's tutorial for the First Light Wizard. This will get you going...joe :) http://www.flemingastrophotography.com/focusmax.html "May...
I can't recall exactly...but with a short focal length I would suggest a step size of no higher than 2 (for small steps), microstep pause of 4, and duty cycle...
Hi Neil and Joe, Thanks for your replies. I'll try the settings you suggest, but first I have some mechanical problems to resolve? The shaft coupling keeps ...
