Telescope Setup - Some Assembly Required - Part 4

Doug Here! Welcome to “Some Assembly Required”, Telescope Setup part 4.
As we continue to assembly the Telescope, we’ll attach the Parsec CCD camera. The
Parsec and Nautilus Filter Wheel fit nicely in the carrying case. The Nautilus Filter
wheel works well; I only wished there were more than four filter slots. When I mount
the CCD Camera I use little stickers with “arrows” to help line up my frames. This
way if I need to remove the camera I can position the frame exactly the same way. This prevents
“feathered edges” when you stack on different corners.
Next you’ll notice I’m connecting the cables to the camera. The cables add a little
bit of weight and you’ll want to balance your scope just as it would be assembled while
taking photos. After I balance my scope I’ll remove the cables. Be careful walking around
the cables, if you’re not careful you could STEP on the cables and break your connectors.
Here’s an illustration of Right ascension movement and Declination Movement. It’s
not important to remember these names, but, you’ll hear these terms, and I wanted to
briefly explain what they mean. If your scope is “parked” and you loosen the Declination
Knob, your scope will move on the vertical axis left and right. If you loosen the Right
Ascension Knob your scope will move on the Polar Axis Up and Down.
Now we’re going to balance the main scope on the Declination Axis. Move your scope on
its side by loosening and tightening the Right Ascension Knob, now we’ll loosen the Declination
Knob. Be sure to hold the scope when you loosen the RA Knob, in may fall heavy on one side.
To Balance the scope move the scope in the Mounting rings back and forth until it’s
not heavy on one side. It should be perfectly balanced. Notice my markers have allowed me
to reach my balance quickly.
Next we’ll mount the Guide Scope. Loosen the mounting ring screws and insert the scope
but don’t tighten the guide scope! We’ll make our final Declination balance with the
guide scope by sliding in or out of the mounting rings.
Now we’ll mount the guide camera and cabling. You may notice how I have wire tied the cables
and hooked the cable to help support the cable weight. The Lodestar autoguider has weak connectors
and if you allow the weight of the cables to drag on the connectors, you’ll damage
the connectors. I’ve also marked the focus point on the guide scope for quick reference.
I can then balance the scope more accurately. Stay tuned for part 5 where we’ll finish
balancing the scope; add the final cabling, talk about finder scopes, and eyepieces. Thanks
