Hey Ray,

Thank you for your kind help. 

Yeah, it's very cold tonight. But it's okay because usually I just press a button a let my automation software to work all the night for me :)

Will follow your recommendations.

Best regards,
Aygen

Hi Aygen,

I'm sorry to hear that you are freezing. :-(

Instead of trying to locate and move the star in the cold, just use the steps where it measures the drift and skip the steps trying to center the star.

So, after calibration:

1. Do steps 4 and 5 (move mount then measure Azimuth error)
2. Instead of step 6, adjust mount while in step 5 until alignment error is less than 2 arc-mins.
3. Do steps 7 and 8 (move mount then measure Altitude error)
4. Instead of step 9, adjust mount while in step 8 until alignment error is less than 2 arc-mins.

So, skip steps 6 and 9.

-Ray

Dear astro-friends,

As I am typing this message (I am out, it's freezing here in Switzerland), I am trying to fine tune my polar
alignement with PEMPRO V3. I need to say that I am just bluffed by the quality of the software.

For my understanding, what shall I do exactly based on the below image ? As per the instructions I need to move
the star to near to the end of the arrow ? I don't see "end of arrow" my azimuth is already well aligned ?

Thank you, very very much for your kind help.

Clear skies,
Aygen

Hi Aygen

While I can't help with PemPro, I can speak very highly of a free and open source polar alignment tool in N.I.N.A's Three Point Polar Alignment plugin. If you are struggling with PemPro you could give this a go. I get near perfect alignment from the boot of my car in about 3-4 minutes. Even if you just used the program for that it may be worth considering. They also have a plugin for AP mounts and solid support in their Discord channel.

Sorry to not answer your question directly.

Re: A note on the video of the SGP and APCC settings for the meridian flip #APCC

 

HI Marcelo 

A couple things

Make sure you are using the latest APCC as mentioned in the video. There were some updates on SGP integration with that and later releases

Is your meridian limit prior to the actual meridian? If so, then yes you need to use negative numbers for the offset. I think the video covered the most often use cases, but having a limit prior to the actual meridian was not one of them

I did some adjusting of the LED Cover on the Dec.  Sliding it around would not make it turn green.  However, I noticed that when I pulled up on it, it would turn green.  So I took some thin brass shim stock and put it between the cover and the mount.  This let me tighten the cover screws and the LED stayed green at all DEC angles.

Re: The AP YouTube Channel

Bill Long
 

Yes Andy, that would be a good video! The DEC installation is practically the same, and the instruction sheet they provide is very good. They should probably encourage people to wear some surgical gloves or something while doing the install (I did wear some). 

I think another good addition to Encoder Install tutorials, would be how to verify the installation was successful, what the colors mean, and for OCD people that want both lights to be blue, how to jiggle the read head cover to get it just right. The last part they don't need to include, but Roland did give a tip on here about how to do that. 😉

I managed to get a break in the weather last night and got another shot with the old Newtonian and the Mach2 combo.

- a stack of 69 x 240 second unguided images with the Mach2

https://www.astrobin.com/gn8egd/

Still a bit of coma at the edges but not too bad.  Used a Baader MPCC at the scope's native f/6.25 focal length [1000 mm].   Again, the tracking model gave me perfectly round stars in the center of the image.

Used the color camera again [ZWO ASI2600MC Pro].

This image was taken under Bortle 3 skies in the San Diego County desert.

A note on the video of the SGP and APCC settings for the meridian flip #APCC

Marcelo Figueroa
 

I was watching the video on the youtube channel about the settings to use in SGP and APCC regarding the meridian flip and I think there is a potential issue.
 
In the video a positive number is entered in Flip Offset Padding while the mount is in parking and that number is correctly sent to SGP. 
 
The problem, at least in my case, is that when the mount is actually tracking and approaching the meridian, there is a discrepancy between APCC and SGP. So APCC always reaches the meridian limit a couple of minutes before SGP and stops the mount, resulting in an aborted session in SGP. What I have to do is to enter a negative number in Flip Offset Padding, this way SGP reaches the meridian before APCC and can perform the flip without problems*.
 

*When you do this SGP will complain and set the minutes past the meridian to 0, simply click the Ok button and ignore the message.
 
Just to keep in mind,
