Intelliscope or Classic - Continued
- There was an earlier post (one that I just can't find now) that
pointed out that use of the object locator and star hopping -
learning the sky - were not "either-or" options - that one could be
carried out in conjunction with the other.
One way to do so is to reverse the procedure recommended in the
excellent star-hopping learners guide "Turn Left At Orion". That
book shows you how to go from the brightest nearby stars to an
intermediate location by star hops in your finder, then what
asterism (distinctive grouping of fainter stars) you should see in
your finder, then where exactly to point your finder, then what you
should see through your main scope.
Doing this in reverse is also possible if you use the object
locator: Use it to find your object, then after studying it in your
scope, make sure its centered, then look in your finder to notice
what asterism you see and where your cross hairs are pointed
relative to that asterism. This will work for you no matter what
kind of optical finder you are using - straight through (inverted
image), RA (mirror-flipped image), or RACI (right angle correct
It often pays to whip out your binoculars at this stage to see what
the asterism looks like through them. Your bincluars - 7x to 10x -
will undoubtedly show you a clearer view than your finder (or than
most finders that those of us with inexpensive dobs are likley to
You might then have a look - either naked eye or through your 1 x
finder - to see roughly where in the sky you are.
The next time you go for that same object - and for teaching
purposes, it might just as well be immediately after this first part
of the lesson - reverse what you have just done: sweep the area
with your binoculars for that asterism, point your finder at
it, locate the cross hairs relative to the asterism, then
finally look through your scope.
And do this again the next time you are out, just to reinforce the
images in your memory.
