The object data base contains a lot of different star catalogues and deep-sky-objects up to the 16th magnitude. It is possible to load orbital elements of comets, asteroids and artificial satellites. HPS stands for High Precision and Speed. With the help of ultra-high resolution absolute-encoders, directly mounted at the right ascension and declination axis, the 10micron GM1000 HPS allows a very accurate tracking.
For the standard alignment I have taken the following procedure before using an external pointing model like for example, Model Creator.
Quick setup and alignment checklist (GM1000HPS)
1. Disassemble the base adapter from the mount unscrewing the four knobs.
2. If you have a Baader AHT or 10Micron 30H100 by Geoptik tripod, assemble the tripod adapter on the tripod.
3. Mount the base adapter on the pier/tripod, paying attention that the protruding block is southward if you are in the northern hemisphere, northward if you are in the southern hemisphere.
4. Put and lock the mount on the base adapter.
5. Adjust the altitude of the R.A. Axis to match roughly the latitude of your observing site.
6. Mount the counterweights and the telescope OTA.
7. Turn on the mount.
8. Balance the telescope following the procedure detailed in the manual.
9. Check that the observing site coordinates and time are correct. You can use an optional GPS module to obtain these data.
10. Clear the previous alignment using the Alignment→Clear align function from the menu.
11. Choose from the MENU: Alignment→ 3-Stars.
12. Choose one star from the list and press ENTER.
13. Press ENTER to confirm the slew to the star; then centre the star with the maximum precision (a high-magnification eyepiece on your main scope, without diagonal mirrors, is preferable) and press ENTER again.
14. Repeat steps 12. and 13. for two other stars.
15. At this point, the mount will point correctly, but if you plan to do any photographic observation, you need to adjust the polar axis position. Choose from the menu:
Alignment→Polar Align and select a star from the list.
16. The system will ask to slew to the star. Press ENTER to confirm. The scope will miss the star. At this point DO NOT centre the star with the keypad; use instead the altitude and azimuth mechanical adjustments until the star is centred. Then press ENTER.
17. Do another 3-Stars alignment by repeating steps 10. to 14..
18. If you like to have a better pointing and tracking precision, select from the menu: Alignment→Refine 2-stars to add stars to the pointing model (up to 25 stars in total can be used). Note: for the best result it's necessary to use more then 10 stars.
19. You can check the orthogonality error and polar axis alignment error by selecting from the menu Alignment→Align Info. Note that orthogonally error does not affect the pointing precision or tracking.
The above quick standard polar alignment is reached by aligning the mount to the north aligning on three stars. By adding more alignment stars the model is refined. An estimate of the expected pointing accuracy is shown on the hand controller after each additional calibration star is inserted.
The usage of a pointing model up to 100 stars allows the correction of the classical polar alignment and conic errors, also the most important flexure terms of the telescope. With the help of a good pointing model it is possible to obtain a pointing accuracy of 20 arcseconds RMS.
10 Micron GM 1000 HPS take three stars and have an ability to do a high quality polar alignment. It normally takes about 15-18 stars on the GM 1000 HPS to generated a polar alignment of 30 or so arc seconds accuracy. After an observing session, the entire electronics box (motor electronics with Linux computer) and HC can be easily detached and protected from premature aging and moisture damage, especially in winter weather.
A virtual key-pad on PC is available for remote control.
