DDM85 standard + 12N: mars 2017 + QSI 683wsg
1- I verify with a level the horizontality of the base of the mount, 4 independent measures.
2- I start AutoSlew Version 184.108.40.206.
3- I verify my geographical position: Mount -> Location -> Latitude and longitude (with http://www.mapcoordinates.net/fr)
4- I verify the hour of the computer: http://www.horlogeparlante.com
5- I connect engines " Motor is ON ".
6- Balance Ok
7- PID sidereal ok J – PID slewing always very doubtful… L
8- I verify the values of "Park 1 Zenith" : Mount -> Park Positions -> Set new Parkpositions -> Zenith -> Az: 180 Alt: 90 – East -> Cancel
9- I click the icon " House 1 " (what's its habitual name ?)
10- I click the icon "White right arrow on green bottom" (what's its habitual name ?)
11- The telescope turns to the zenith. Almost… … …
12- The counterweight shaft is in the East.
13- The counterweight shaft is too much raised in east of 2° (14mm for 400mm measured)
14- The top of the tube is tilted to the south of 3 ° (20mm for 370mm)
15- This error is systematic, and very precise (absolute encoders - false here but reproducible !)
16- I take a photo such as.
17- I look in Stellarium where I am lost (near zenith).
18- The error measured from zenith by Stellarium is regularly 3° 40'
19- I center one of the stars in this picture.
20- I make Sync in Stellarium (Ctrl+3).
21- I slew to NGC4565. In the center of sensor J
22- The problem is solved until the next day.
23- I don't find the page of the documentation concerning this situation?
24- But… exists in Menus : Mount - > Set new homeposition - > Please confirm that the telescope up is synched and centred and you want to define has new Offset for the Home-Reference mark.
- "Synched" with what?
- "Centred" on what?
- what is "Home-reference" ?
- what's the goal of this?
- I don't use this L
25- After several cycles Pointing File, and Polar Align (< 1 arcmin), imaging of 900s of NGC4565 show the beginning of the strain of stars. When everything goes well. It's very rare… Picture is here :
26- I have many other problems important to solve, after J
27- Thank you for your help.
