New ASTELCO NTM-500 Mount - Browse Images - 22

I just cleared my new Astelco NTM-500 GEM through customs today. It is a monster! If it weren't for Stephen I never could have gotten it out of my van! I still have some preparations before I install it though. The waiting is really tough!

30 November 2008 Frank Colosimo and Stephen T. Roffo, Jr. Come to help me install the mount. Other than the grunting when trying to move this monster it went pretty well. We had to do some machining of the Losmandy dovetail to fit into the saddle properly. After we stopped being dumb we got the software to connect to the mount quite easily.

The scope was back heavy in declination so I ordered a sliding counter weight system from Losmandy that solved that balance problem. I also ordered an additional counter weight for the RA axis which solved that balance. The mount and OTA are now balanced in all three planes.

I had an electrician build a 110 Volt power cable to connect to the custom connection on the mount and replaced the 4 wire plug on the extension through the mount with a female US power plug. This brought the power up to the scope. After Frank pointed it out to me I purchased a junction box that was 8 x 8 inches and modified it so all my interface boxes for the Optec Pyxis rotator and FLI DF2 focuser as well as the USB hub and power supplies could be contained on top of the mount rings. I have some pictures of the box in the set below. I then routed the cables up to the box and secured them so the mount can move and the rotator can turn freely.

Next I need to polar align the mount and then build a pointing model before I will be ready to image.
