Is that your 10" Mak Cass Astrograph?
Yes, 10 F6.3 Mak-Cass, QSI-WSG8, 130GTX, QuadTT, and ZWO 2600 Cmos. Along with several dovetail plates, etc.

That's awesome. I have not had any problems with my 12.5" iDK and PL16803 on the Mach 2. I did not try adding a GTX on top though. I would not have enough counterweights to safely do that though.

In order to see the effects of really overloading the mount, I put about 80 lb of equipment on it and moved the counterweights way down on an extended shaft, as you can see in the image. Yes indeed I got some ringing at the end of a long slew, especially when the scope was pointing up towards the zenith. With a little change in the parameters i got it to be perfectly stable, and it tracks like a champ. I don't recommend putting this much on the mount, and it would be better to have the counterweights higher up the shaft of course.

However, if you have anything resembling this setup, or are using a smaller diameter counterweight shaft with heavy counterweights, and have ringing at the end of a slew, then drop me a line at chris1011@... and I can help. Please include a quick snapshot of your setup, if possible, and the amount of weight the mount is carrying if you know that.

Hi Roland

I don't have any ringing with my setup but I was wondering if having those cable bundles just hanging off the back of the cameras in your setup can cause guiding issues with non-AE mounts. 

I use a similar cabling arrangement as yours with my non-AE 1100 mount (see photo), but I suspected that the long, free hanging cable loops might have created some guiding issues, so I started tying them off at the mount to make a shorter loop to minimize the weight pulling on the camera.

In Photoshop, open the “Help” Menu at the top all the way to the right. Type in “Channel”, press Enter and click on “Channel.” You will have all kinds of options on how to set up your channels.

Some quirk of Win10 - see below

To view the "ProgramData" folder you will need to go to the Windows control panel , select "Appearance and Personalization", and find the "folder options" dialog. Select the View Tab, make the changes shown above, and click OK. You should now be able to see and access the "ProgramData" folder.

Re: Question: ROLAND’S GTO QUICK STAR DRIFT METHOD - 2020 VERSION

Roland Christen
 

First question; Yes it works even with horrible orthogonality.

Any idea why the Altitude had to change considerably after leveling in Park 5?
This question is quite easy: The parks are governed by the time you have set in the keypad (or your laptop). If you are off by 1 hour, the parks will be off by 15 degrees in RA. For every second that you are off, your park positions will be off by 15 arc seconds.

This is also a way to check your exact local time - simply change the time in the keypad by a minute or so (or even a few seconds) and park again until your park position is exactly parallel to the earth. Presto, you have now synchronized your time to the stars.

Subject: [ap-gto] Question: ROLAND’S GTO QUICK STAR DRIFT METHOD - 2020 VERSION

Hi,

   I have a question about Roland's Quick Star Drift Alignment Method as documented in the Mack2 User manual. (Appendix C on Page 41.) I tried it out the other night and all seemed to go pretty well. The Azimuth Alignment step went perfectly and was easy to perform. I did use a shortcut of sorts by simply doing a Plate Solve and Recal just West of the Zenith before slewing to a star in the south just West of the meridian.

   My main question is whether (or how much) this method depends on having previously corrected for any Orthogonality / Cone Error of the OTA. I had quite a bit of East / West offset difference when I performed the second stage of the method to dial in the Altitude adjustment. I was surprised at how much I have to change the Altitude axis (nearly a full turn of the Altitude adjuster) to move the star N/S to get back to the crosshair. I had started by using the Park 5 / Level OTA initial adjustment before beginning this method.  Any idea why the Altitude had to change considerably after leveling in Park 5? (I  pretty much trust the Level since I have calibrated it carefully and get exactly the same repeatable reading when turning it 180° with less that 0.05° reading difference.)

   So, back the main question; does this method work equally well even in the presence of orthogonality error? I really like the method as it is very , very fast but wonder about the E/W star offsets I see when adjusting the altitude of the RA axis in the second half of the procedure.

Re: Question: ROLAND’S GTO QUICK STAR DRIFT METHOD - 2020 VERSION

John Upton
 

Hi, Again.

   I see a typo in my first post. The mount is a Mach2, of course, rather than a Mack2 -- although it seems as a stable and robust as a Mack truck.

   I have a related question about Orthogonality error. When you use the Orthogonality (Ortho Model) correction method in the KeyPad to correct for orthogonality, does this "stick" in the CP5 control box or KeyPad? (I cannot find where I read it but think the correction value is actually stored in the CP5 box. Right or wrong?)

   So, if I perform the KeyPad Ortho Model correction procedure, I understand that creating an APCC model will override it. However, on a subsequent night after having moved the mount, does the KeyPad's orthogonality correction apply once again if a new model is not created (since the old model will not be valid)? Or, do I need to rerun the Ortho Model procedure on the KeyPad again?

   If the KeyPad correction is always present, then it should help with the E/W offsets I see when performing the polar alignment method in the first post. (Or, I could be completely off base.)
