Re: which pelican case for MACH 1 GTO?

I use a Storm iM2720. Not as sturdy as a Pelican but lighter and strong
enough.

I have mine in a 1650 with room to spare for the shaft and control box.

NGC 185 with eight extragalactic globular clusters

ayiomamitis
 

Dear group,

It took a few days due to cat-and-mouse games with the clouds at night to process my
results from a few nights ago involving the dwarf galaxy and member of the local group NGC
185 in Cassiopeia.

Aside from being bound to another dwarf galaxy, NGC 147, less than one degree away, NGC
185 is also known for its eight globular clusters which range in magnitude from 16.6 to 19.7
and are aged from 5 to 10 billion years-old.

For the result which includes all eight globulars, please see http://www.perseus.gr/Astro-
DSO-NGC-0185-GCS.htm (the image is hyperlinked and clicking on it loads a larger photo).

For a similar result from last year (NGC 205) and which includes fifteen clusters in and
around NGC 205, please see http://www.perseus.gr/Astro-DSO-NGC-0205-GCS.htm .

Please no enquiries as to the availability of my AP160! :-)

Anthony.

Hi Mike,
There are 970 "buckets" in the GTOCP3 non-volitale memory dedicated to PE corrections. This is true regardless of the gear ratios of the mount it is configured for, or how long one worm revolution takes. With the AP1200, for example, this is about five correction points every two seconds.
Wow, that's great. That's 11X the number of buckets that were used in another mount I owned. Thanks very much.

Re: GPS time

Joe Morris <joemorris@...>
 

Hi Dave -- If all you want GPS to do is provide accurate time at a
site where internet hookup isn't available, take a look at this free
program http://www.coaa.co.uk/gpstime.htm I've been using it with a
portable Garmin device and it seems to work fine.

one reason that I would like support for a GPS, to keep accurate

The clock in my AP1200 can be off by a couple of minutes after a few
weeks of not
checking it. Maybe I have a bad clock chip, but if I could connect
my old Garmin handheld
GPS to provide a time signal to the mount (via NEAMA? or Garmin
protocols), my PC (set
via NTP) an my mount & hand controller could all be in sync.

If Pulseguide ASCOM support is ever provided, it will probably be
more of a moot point,
because it will hopefully be easier to simply send the PC time to
the mount. I wish there
were a driver setting where I could specify that I trust my PC's
time and always send it to
the mount when I first connect (If there is in newer drivers, my
apologies, I haven't
updated any drivers in a while).

Question, who is actually keeping the time in the mount, the hand
controller or the servo
controller?

I use the hand controller to park / unpark and initially sync my
mount. All other goto's are
controlled from Thy Sky 6 (and MaxIM DL through The Sky 6). I use
the AP support from
The Sky 6 because it handles the case of powering down the mount
after parking without
first disconnecting (the last ASCOM driver I used went nuts for this
case). Does anyone
know if the ASCOM driver has been improved for cases like this?

Thanks for listening / any answers,

No problems....although they do experience some movement when moving them up

To mount an AP1200 to one, yes you'll need the Astro Physics 'flat surface

Re: GPS time

Howard Hedlund
 

Right now, one of the remaining issues is the cable. Originally, as I
understand it, Chris had produced a cable that used the GTOCPx's 6 volt,
3.5 mm receptacle to power the GPS. Apparently, some of the earlier
testers experienced problems with the power connection, although I was
never aware of any other problems on our end with the 6 volt receptacle
on the control box. He then decided to make a small cable that
included a small battery module for a AA battery. This battery module
employed a voltage pump to provide adequate power for the GPS unit. I
have tried both cables. Both have worked fine for me. The original
cable for the 6 volt receptacle would probably be preferable if we can
be sure that it won't have problems. I have only had a chance to try
it a couple times, but so far I've had no failures. I would call and
talk to Chris about which cable he is recommending.



I'm sorry that testing this and helping to make it available has taken
so long. The problem has been that I can only test it out in the
field, since the GPS will not work in our metal-roofed building.

You can use the free Dimension 4 <http://www.thinkman.com/dimension4/index.htm> to synchronize the PC's clock with an NTP time server.

The ASCOM driver will send the computer's time to the mount when you connect.
If you use the ASCOM driver to set the amount's time, you can later set the hand controller's time using the "get time from mount" menu item.

Granted, you have to remember to do this, but it seems like a good way to maintain an accurate time in the hand controller.

J2000 and the AP1200

Mike C
 

Thanks Bob and Roland.

Next question... MaxPoint says this about a checkbox called "J2000":

"For most telescopes, the epoch used for positions is the "epoch of
date". This means that precession and nutation are taken into account
when sending positions to the telescope. A few telescopes do the
conversion from J2000 automatically within their electronics; in that
case only, you should turn on the J2000 check box."

For the AP1200, I should leave this J2000 box cleared?

Mike Clemens




Yea, Mike. Set them to 0 and let the mount itself handle the
limits.... That's the safest and easiest way to go ad well.

Take care,
Bob

Christopher Vedeler L.Ac. <vedeler@...>
 

I personally consider not messing with our clocks twice a year one of
the greatest benefits to living in Arizona... Ok over 300 clear nights a
year is probably the best benefit but that is beside the point. For
astronomers with fancy computerized mounts daylight savings causes
nothing but confusion. When I lived in New Mexico and even in Idaho I
simply set my clock to what-ever time it was with the appropriate GMT
offset and left it year round. Funny how I was still able to point
accurately to things. I don't recall ever going to my telescope mount
to determine what clock time it was. It doesn't matter if its clock is
off by 1 hour from my wall clock as long as it is set appropriately to
GMT so it can know where the planets are and what is above the horizon.

Hi All,

I never liked this messing around with time zones and DST. It should
be practice to set the observatory PC to GMT and leave it like that at
