Re: Mounting requirements for a Stellarvue SVR90T

rtlangland
 

Hello,

Hopefully I can provide some useful information. My first suggestion would be to contact George at Astro Physics. See what he says. I have an AP 1100 mount and am using it with a Stellarvue SV102T. It comes with a Vixen mounting rail and I suspect that your Stellarvue SVR90T also uses a Vixon mounting rail. I used to have a Stellarvue SVR90T but never used it on the AP1100 but it had a Vixen mounting rail.  If my information is correct, neither of the Dovetail Saddle Plates you have referred to in your email will accommodate a Vixen mounting rail. 

I am using the10” AP Saddle DOVEDV10. It will handle both vixen and Losmandy mounting plates. I have no trouble with the end clearance with this mounting plate as the overhang provides plenty of room for a flattner and the DSLR camera attached to the focusing tube.  I am also using a Stellarvue SV070T on the AP1100  mount. However, because it is a much shorter focal and tube length, I need to use a set of risers attached to the standard vixen mount so the camera assembly clears the mounting plate.

Hope this is informative. My guess is that you would not need risers for the SVR90T because its focal length is about the same as the SV 102 that I am currently using on my AP1100 mount.

Was hoping somebody might be able to confirm that the following should allow me to mount my SVR90T onto the 1100GTO?

- 16" Dovetail Saddle Plate (DOVELM162)
- 16" Versatile Dovetail Plate (SBD16)

Would adding Riser Blocks be a good idea to gain some extra clearance?

Thanks

Hi
Just a follow up to this thread in case someone else runs into this.  Ray logged in to my computer and immediately saw where the issue was.  I was accessing the  CP4 directly instead of going through the ASCOM drivers.  The ASCOM driver manages the display of the emergency stop.
As to the mount not showing up, not resolved, but appears to be related somehow to a bug in Windows 10 related to broadcasts.
Thanks Ray!!

I hope my fellow Californians will forgive the topic title—we've had too many fires lately. But this picture does remind me of a long streak of fire in the sky. I've always wanted to image this one. I used my new ASI294MM Pro camera, Starizona Apex ED L reducer, and Astrodon 5 nm filters. My trusty Mach1 performed flawlessly night after night, as it always does. I chose the HSO color palette rather than my usual SHO because the resulting colors enhance the flame-like appearance of the nebula.

The flip feature is in the keypad. You will need the latest keypad software. Press +- and then button 9 to bring up the meridian delay and the flip mount features.

Hi Gentlemen, 

Before I purchase the CP4 controller (that you have indicated above will give me simple press button pier flip functionality), could you tell me what the hand-controller path for it is please? I downloaded the CP4 manual but I couldn't find any instruction for performing a simple press button pier flip. Thank you again.

Re: Mount keeps going to zero tracking

Ray Gralak
 

I have a couple of other suggestions/problems with APCC.
I cannot view the error logs or close the errors even if I select the error log window.
The error log window does not open if you try to open it from the Tools menu in APCC? ("Open Error Log Window...")

It is difficult to partially minimize the screen to use it to
move the mount while seeing the effect in another application.
You cannot unminimize SGP or PHD2 from the
tray if the APCC screen is up.
Do you mean APCC always hides SGP and PHD2? That sounds like you have "Keep APCC on Top" enabled in the "Program Operation" group box. If you uncheck that option then other applications will not be hidden by APCC.

Also, when APCC's main window is not full screen, you can resize it. The fonts and controls will resize themselves the best they can to try to fit the size of APCC's window.

The issue must have been triggered by SGP...it really disrupted the evening. As I said, it resolved with a new

Re: Mount keeps going to zero tracking

Ray Gralak
 

Peter,

I had this problem a couple of nights. I set tracking to zero to focus on a terrestrial object. I set the mount back to
sidereal and entered a target in SGP; when I attempted to center in SGP APCC kept going back to zero rate
after I repeatedly set it to sidereal. I finally seemed to solve the problem by starting a new sequence. Here is the
log:
I looked at your logs, and APCC stopped the mount under these conditions:

1) When the mount reached a meridian limit.
2) After unparking because you have the option set to stop tracking after unparking.
3) After parking, because that's normal.
4) After an Alt/Az slew, as that is an ASCOM requirement.
5) When a command came in through a virtual port to stop tracking.

There were no unexpected cases where APCC stopped tracking.

Re: Tracking much better after meridian flip

Terri Zittritsch
 

Tom, I had a similar situation where I was getting mostly flat line guiding on one side of the meridian, and after the flip, it was much poorer.. I had reported this in an earlier post and saw this repeatedly (on different nights) for the same target.    It didn't make sense to me that the atmosphere had changed in those few minutes each night during my meridian flip.   And given the scope and associated guiding goop were also in substantially the same orientation, I racked my brain for what is causing this.   One thing that I did find, is that a different star was chosen for guiding after the flip that had a significantly worse SNR.   While not entirely conclusive, this may have been the case for me.        You'd think that after a flip the same stars would be visible and the same star chosen, but this wasn't the case for me.   I have never been very careful about aligning my guide scope to my main scope, and never really found it to be an issue, but in this case it may have been a contributor to my issue.     In any case, something to check.

Re: Tracking much better after meridian flip

 

Hi Tom

what are you guiding with, and do you have guidelogs to share?

I'm getting ok guiding when I start my night imaging.  At this point, the scope is pointing to the east. Not fantastic but still good enough for my image scale.  I do have a bit of backlash in dec and the mount is the AP600e known for a sticky dec axis.  
However, when the mount crosses the meridian and does the flip, the guiding is way better.
What could be the reasons?  The mount is counterweight heavy for imaging in the east.  I would think it would get worse when the flip occurs.
Thanks for any tips.

Hi
I turned off Save windows positions and it does not make any difference. I also checked the task bar to see if the
window appears along with APCC and the 3d scope view. Nothing shows up.
Normally when a window if off screen you will see the outline and can do a move. But there is not indication of
an emergency window.
Maybe on a restart.
