Manufactured dome recommendations?

Posted By Douglas Westcott

I too have been looking. Anyone seen Mooshine dome? They are less money than Home Dome or Sirrus.

CLEANING SOLUTIONS FOR COATED LENSES

Posted By Douglas Westcott

Kevin, Try Dr Clay's receipe found at www.arksy.org, then click on Guides, then pick the cleaning systems item. Dr. Clay has spent a great deal off effort to get an acceptable cleanoing solution for Meade LX200 UHTC optics which are coated.

snow on roof ?

Posted By Douglas Westcott

Put a heat source in the building and melt the bottom layer of snow, it should then be easy to pull it off with a broom or the like. If you have a propane BBQ grill and it will not smoke up the building, it should do the job very quickly.

Anyone out there Have a Sirius Observatory?

Posted By Douglas Westcott

I will be picking up my 2.3M later this week. I saw the 3.5M at NEAF. Yes, the lower portion of the hatch cover is hinged. The dome appears to be well built. Support for Sirius appears to be good. Note that robotic options are not cheap for any of the dome manufacturers. Good luck on your choice.

I now have mine all installed. Make sure you get a copy of the Sirius CD as the assembly manual is not very good without seeing the video on the CD.

Pier height/placement??

Posted By Douglas Westcott

Normally the first 15 degrees off the horizon are not used in observatories, there is too much atmospheric distortion. So don't worry about the dome being somwhat higher than the scope, but pay attention to the hieght.

Also a wedge should have an offset pier. The offset is to the south and depends on the wedge and SCT you use. Remeber that the fork arms are tilted which throws off the center point for the scope. With a dome you want the pivot point of the scope to be the center of the dome. My pier is 17 1/2 inches south of the central point, other wedges need only 4-6 inches.

Observatory lighting

Posted By Douglas Westcott

I use 6 traffic light red LEDS plus battery holder (AA) and some switches from Radio Shack. Works just fine, batteries last a long time (50+ hours). Cost was about $20. I can provide pictures if you want.

Re. Pier Placement?

Posted By Douglas Westcott

Fork mounted SCTs need to be offste to the south. GEM mounts do not need to be offset.
