Note to a friend regarding DSCs... from D. Bagley:

Over the past decade, I have come across a variety of people who have
expressed dislike of setting circles in general.  In short, the vast
majority of people I have conversed with just don't like the setting
circles that came with their equatorial mount.They all had different
reasons that they didn't have time to go into, but the short of it is
that they all seemed to have a reason for not liking setting circles.
And, that about sums up my belief of ten years regarding setting circles,
GOTO's, and tracking devices.  Except the clouds just rolled in, so I
have time to go into the different reasons why I didn't or don't like
setting circles.

I had setting circles on my equatorial mount, and there is something
there on the Quantum 6 as well.  I hate and hated them.
I just always felt like it was a more laudable goal to 'know' the sky and
use a Telrad or 8X50 finder to find things.  And, there's just something
honest and pure about pushing a dob.  I also like silence, and the sound
of an LX200 coffee grinder just turns me off.
I didn't like my equatorial mount either.
I don't talk about it much, but at my inner core, I am somewhat techno
phobic.  I think that is partially why I avoid photography, equatorial
mounts, GOTO's, and CCD cameras -- I don't think I would get them, even
if I could afford them.  I did try the equatorial mount though.  I don't
like the internet at times for much of the same reason.  I am a simple
person at heart.

When Todd sold me the 16 incher, I tried right and left to get him to
keep the encoders and drop the price.  The encoders were mounted
specifically for the scope, and he would have had no use for them, so he
wouldn't budge.  I probably wouldn't have gotten the digital setting
circles, thanks to my inner techno phobia, except for the fact that the
scope came with encoders that I was forced to buy.
I have watched the battle rage on sci.astro.amateur pro and con against
computer assisted devices.  The one camp says that real men don't need
all that, and that if you can't find the object the star hopping way, you
have no right finding it.  That's basically where I was.  Then the other
camp would say something like, "A real man is humble enough to realize
when he needs help, and humble enough to accept help when it is offered."
 Over the last year, the second camp has been influencing me.
I corresponded a lot with Joe Donahue, and he lives in the suburbs of
Philadelphia; he has the same kind skies and light pollution that I have,
as best as I can tell.  I have health reasons why I don't like to drive;
my wife does the driving for the most part.  For some reason, Joe Donahue
doesn't like driving to a dark site either.  Anyway, over a year of
listening to me whine about not being able to find anything, about every
other month or so, he would subtly hint digital setting circles at me.
Joe was finding tons of stuff through his neighbor's lights and Philly's
light pollution.

One of the things that convinced me that I really needed help was when I
spent 20 minutes looking for the Ring Nebula because I could only see
Vega through the Telrad and none of the rest of Lyra.  I also realized
with my current job schedule, it was going to be potentially years before
I would be able to work in a desert session.

So, I fought the techno phobia, and got the digital setting circles.  I
have to admit, I like them a lot more than I could have ever guessed.
They are just different than other types of setting circles.  Viewing
through cloud cover was a hoot the other night; and, I have wanted for
five years to start a double star viewing program.I am finding double
stars right and left with the digital setting circles -- could never find
them through the Telrad or 8X50 finder.  Last summer, I spent 15 minutes
one night looking for Albireo, because I couldn't see it through the
Telrad.  For some reason, I have always loved double stars since I
started the hobby 10 years ago.  It's so fun to find them here in the
city, and the digital setting circles makes it easy.  When I went to the
desert, I never looked at double stars.  I considered it a waste; I
basically used the darkness to seek out and study galaxies and
nebula.And, of course, I could never find planetary nebula here in the
city, not to mention galaxies.  I spent a half hour one night last summer
looking for the Dumbell through the Telrad.  I have already seen more
planetary nebula with the digital setting circles than I had over the
past 10 years combined.Anyway, Joe Donahue called it right for my
situation.  He was convinced that I would really like digital setting
circles, and I must admit that I honestly do.  Sure, I am no longer a
'real man'; but, I have to honestly admit that I was kind of getting
tired of looking at the Orion Nebula and Jupiter.  I just have to swallow
my pride and join the ranks of the wimps that need help.I think the DSC's
will probably rank as this year's best astronomy purchase for me.
Another thing I like about digital setting circles and encoders are that
they are absolutely quiet.But, I still don't think I will be taking the
digital setting circles with me to the desert.  I only needed a Telrad in
the desert at the dark sites.  In the desert with a Telrad, I found
everything I looked for, except the coat hanger asterism.  I might have
found that too, but there were so many stars in the Milky Way, that I
couldn't separate the asterism from all the stars.  I think the back lit
LCD of the digital setting circles would ruin dark adaptation by two or
three magnitudes.  I have it on the lowest setting, and it is still quite
bright.  I still believe that digital setting circles are meant for the
city, and the brightness of the display kind of indicates that the maker
of the unit kind of thinks so too -- need to be able to see the display
above the neighbor's lights.At the desert, I refuse to look at planets,
and first and second magnitude stars, as they too ruin the dark
adaptation.  I am kind of a purist when it comes to my efforts to achieve
dark adaptation in my desert trips.Anyway, when I go galaxy hunting at a
dark site a year or two from now, I won't be taking the digital setting
circles with me to ruin my dark adaptation.  The Telrad is bad
enough.Well, time to let you go.  But, I had to let you know that I can
still understand the sentiment that setting circles are the pits; I still
somewhat share the view.   But, I can no longer fault the folks who fall
for them, as I must admit that I have fallen for the digital setting
circle variety.Darwin Bagley
