I have a new G-11 and a new house. A monster tree in my new neighbours yard

makes it impossible to see Polaris. At times I can see the big dipper

pointer stars. Any suggestions on how I can still get even a rough polar

alignment??

Dear Manoj:



I have been successful at polar aligning using a magnetic compass for

asimuth and the G-11 elevation angle scale for elevation. In doing this,

remember to first level the G-11, and correct for magnetic variation from

True North for your geographic location. The benefit of this technique is

that you can do it during the day.

Manoj-



You might try this.



First do a one-time good polar alignment somewhere near your home

after leveling your mount. Once this done your elevation is set

properly. From now on your elevation is set as long as you level

the mount. The difficult part is adjusting the azimuth.



Set up the telescope where ever like and level it. Next find out

what the local sidereal time is. You can do this buy using any

planetarium program, the program Astro Clock, or a good

planisphere. Don't forget to adjust for on daylight savings

time.



Now rotate the RA to position the counter weight shaft so that it

is exactly level. Use a bubble small level to do this. Set the

RA setting circles on the mount to the local sidereal time. Note

that the hash marks are in 4-minute increments.



Using the setting circles, position the telescope to the

coordinates of a known bright star (Vega, Altair, etc.) If you

look in the eyepiece or finder scope you will see that you are a

little bit off. Adjust the azimuth on the mount to come as close

to the star as possible. That should get you in the ball park.

Thanks James - I will try it and let you know how it works out. I now have

2 methods to try.
