Jeff, that's the beauty of what we can do with our hobby.  What we are able to produce to suit our own tastes is far and above what I, and countless others, were able to do in the 1980s and 1990s with hypered 35mm film and manual guiding.

There really is no "wrong" palette.

Honestly, I like the original with the more prominent red and blue.

The following is my revision that portrays a more "natural" color palette, if one could consider NB natural.

Eric,

 

I am no knowledgeable critic, but I enjoyed the purple version.  I like this rendering very much, as well.  It’s quite calming.

No matter what, my 2017 Mach1GTO has produced better results than any mount I've owned in the past 35 years.

Wonderful colors. I think it was a great improvement from the original version. Congratulations!

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. 
 
Thanks for the info. My SVR90T was the 'Raptor' version, and I don't believe it came with any rail, just the clamshell. I used to just mount it on a photo tripod using a Markins plate.

On further investigation, and some measurements, I think the 16" Dovetail Saddle Plate (DOVELM162) would be ok. Then I should be able to mount the clamshell straight to a 12 inch dovetail plate (SBD12) as it has built in clearance. The SBD16 would not have worked as it didn't provide any clearance and was far too long.

Does George hang out here? Confirmation of my expectations would be great.


Re: Meridian Flip Feature Yet?

Roland Christen
 

The flip is not based on meridian delay. The scope flips when you press the button. This feature is in the CP4/5 version P02-08 and is activated via the latest keypad software.

Hi Rolando, 

Is this pier flip based on meridian delay? Or is it an instantaneous dedicated flip feature? And is the hand controller path inside an AP instruction manual somewhere? I want to check it before purchasing the CP4 that I'm told I need, thanks again.

Hello,

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


Re: APCC emergency stop no longer showing up.

Tom Blahovici
 

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.

Re: Mount keeps going to zero tracking

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.
