Hi Mike,
CCDCommander will allow you to program it to jump back and forth as
well as many other things. Setup wil be especially easy if you have
TheSky. GO to the web site. There is a free trial for 30 days or
more. This is $99. Robofocus would cost you $425 and Focus Max is
free, and that would be all that is necessary for full automation
(assuming that you already have CCDSoft or Maxim).
Thanks, Rick

Hello

I have an AP1200.

My requirement: I need to jump back and forth between my selected
composition/framing of an object, and a bright star suitable for
repeatedly focusing with different filters.

I am doing this by

1) slewing to a bright "focus star" near the intended target,
doing a
calibrate on it,

2) focus the camera

3) Then I do the short slew to the main target, and carefully frame
the image. Once the picture is composed, I go to object menu and
press
">" which seems to cache the RA/DEC of the current position for
later
retrieval.

4) When I'm ready to change filters I slew to the bright star
again by
name, and do the filters & focus work.

5) When ready to take photos again, I go to the objects menu and
press
"#7 - R/D" which has the coords of my careful framing remembered.

Repeat 4-5 for each filter or photograph series.

I know the easy way to do this is a robofocus and a filter wheel,
but
pretend I don't have $1200 for that stuff right now... Am I doing
this
repeated change between two sky positions in a silly manner?

Is there any handy software where I can tell it to remember a
number
of sky coordinates and just simply click on them A.. B.. A... B...
to
go between them?

Thanks!

Re: Leaving as GTO mount outdoors O.T.

Wiggins, Rick
 

Hi Guys,
Is electricity free out there? Out here in CA, electricity is very
expensive and I haven't calculated it, but would guess it to be much
less efficient (dollar-wise) than gas. The guys here that had the
original GM electric cars said their electric bills soared and
electricity has quadrupled since then. I think Toyota is on the
correct path. Their hybrids convert waste kinetic energy into stored
chemical energy (a nearly free other than the battery circuit
costs). The plug-ins connect directly to my wallet (Southern CA.
Edison in my case). I hope to continue to see use of the wasted
energy in addition to more cost/energy efficient fuels.
My O.T. 2 cents,
Thanks, Rick

Hi Morgan,
Have you seen the little boxes that some people have made? I
wish I
had a link to them, but will attempt a brief description.

Imagine the closed position of a wooden box around just the
top
of
the pier and just big enough to cover the mount. The box comes
in
two pieces that fit together with overlapping weather seals.
It
has
a round cutout in the bottom to fit around the pier and spring
loaded closer hasps to seal it tight when closed.

Another version has two flat pieces that fit together just
below
the
mount and around the pier to form the bottom of a box and then
a
top
hat box that fits over the mount and clamps to the bottom.

Top off the design with a 15 watt light bulb and some bottom
vent
holes to allow minimum air flow and I think you have a winner.
Even
better, cover the mount first in a nice warm, breathable, non-
hygroscopic blanket (i.e. Gore-tex fabric) first, then cover
it.

Just another idea.
Thanks, Rick

Re: is this a sane workflow?

Hi I am using the keypad only. So perhaps I am already using the
simplest method for jumping between coords "A" and B" with the keypad.

I like Rolands idea but its expensive. Sometimes I am sure there will
be a star that falls on even my puny sensor once framed : ) That
would be nice.

TheSky sounds very nice.


Mike

Are you using a planetarium program to control your mount? For
instance, in theSky6 pro, if connected to the mount and controlling it
with theSky, you can simply slew to your focusing star, do your focus
routine, then slew to your target and frame etc. Once done there, you
can synch your position; once done with imitial imaging, you can go to
the button "slew prior" and it will take you back to your focus star.
Do your second focus, then hit the slew button to take you back to
your target. You can do this all night if you need to...very simple,
very few steps.

Sync vs Recaculate

Dean Salman <cluster@...>
 

In the Sky6 0.57 version a new button was added. This is use to sync
the Sky with the AP mount. Clear enough. Does anyone know what the
software will use (like Maxim DL) when it plate solves and does a
sync. I don't want it to do the wrong one which is why I turned that
feature off. I know this is a software question, but I thought I would
try here first.

In any case, your curve is smooth, so PEM should work fine with your mount,
much better than a small PE that shows sudden jumps.

600E PE "Normal"???

Bob Benamati
 

Hi folks,

I'm wondering if the result I'm seeing is "normal" with my recently
acquired 600E (while I wait for a 900 or Mach1 <g>). I've uploaded
an Excel file to the Files section for those who might be able to
help.

PEMPro gave a +/- 25" error--which stunned me... It does seem that
the worm is running slow(?) for the majority of the run. Any ideas
as to what I'm seeing here?

The mount's carrying an 8" M806, Pyxis rotator, and ST8. Probably
right around 27 pounds--so probably overloading a bit, but I believe
it's pretty well balanced. Other than the PE concern, though, the
mount ran great last night and guided fairly well after programming
(was able to get it down to +/- 8", but need to run a few more curves
to refine--maybe I can get better).

Any thoughts/advice would be greatly appreciated!


Thanks,
Bob

I concur that the manual is quite good and should be read. It's not
like the Meade manuals which leave rather much to be desired. (I can't
speak for Vixen, but if their translations are anything like
Takahashi's, well, they can be pretty rough going.)

One thing though -- if you bought your mount used then download the most
recent manual off Astro-Physics' web site. Whenever they find something
that wasn't explained well enough in the manual they tend to update it
-- so the most recent one is by far the most clear.

-- Jeff.

The mount is "parked" in any position you when you power off.
There are
three designated park positions as referred to in the manual. I
highly
recommended a through reading of the manual. You can also
configure your
mount for auto-connect which means it reads your time and
location that you
have programmed into the hand controller. When you power on, the
mount is
automatically initialized and starts to track. You can slew to
your targets
if Polar aligned. The manual gives you all the necessary
information and is
quite clear. It should be read before trying to do anything.

If you are referring to using PemPro for Polar alignment, the
program sends
the code by itself. If you are using some other program and it
does not send
the code then look at your tracking rates. There is a stop rate.


If you loose power or turn off the power to the mount, it is
parked. Simply
turn the power back on and it knows where it is already unless
you have
physically moved the mount. Again, and I can not stress this
enough, read
the manual. I don't know anything about using the mount in the
Southern
hemisphere but I'm sure the manual covers any differences
between Northern
and Southern hemisphere operations.

HTH,

Steve

600E first light

Morgan Spangle <msfainc@...>
 

Finally had a good night last night and took out the Questar 7 on the
600E for some visual double star observing. Setup was easy - I used
the polar scope (pasill4) from my 1200 mount (I didn't tune it to the
600 before using it, so it was probably a little off), and followed
the 2 star routine in the manual, using Dubhe in the east and Procyon
in the west; did three iterations and according to Tpoint, that
brought me to 7 arcminutes west, and 12 arcminutes south of the pole.
Question: on my 1200, you know what one turn of the fine az adjusters
means in terms of arcminutes; is there a similar known value for the
alt/az adjusters on the 600E?
Anyway, I couldn't get the stars to converge on the center but I
figured the alignment was close enough for visual observations; plus,
I hooked up to theSky6 and did a short 12 star Tpoint run - after
that, every target was in the field of a 16mm Brandon - at about
2750mm focal length, I thought that was really good! Using
astroplanner to control the scope, I ran through a list of doubles in
CVN and COM; the seeing was really good, tho there was a high haze,
but I was still able to split an unequal Struve double at 1.1
arcseconds - fun! All in all, the time flew while I was enjoying the
views. The mount held the Q7 rock solid. A lovely spring evening...

The mount has 4 tracking rates: Sidereal, Solar, Lunar and Stop. The last one
will stop tracking. It's on your keypad in the Main Menu.


2. If I switch off (accidentally or power failure) how do I resume use,

Place the keypad in Autostart YES mode and it will automatically start every
time you turn power on. Turning power off will park the mount in the spot
where you left the scope. Turning power back on automatically resumes the mount
from the previous position. No need to do anything else.

Howard,

A while back you said that AP was investigating a serial / USB
converting
device. Has there been any progress? I recall that it was a single
company's
device that had caught your attention.

Thank you,

George

Having a bigger chip is the key to fast focusing. With a big chip like the
ST10 or STL11k, there is always a star somewhere that can be used for focus. It
is then a matter of simply defining the focus point by drawing a little box
around the star that the software (Maxim) remembers.

Hello

I have an AP1200.

My requirement: I need to jump back and forth between my selected
composition/framing of an object, and a bright star suitable for
repeatedly focusing with different filters.

I am doing this by

1) slewing to a bright "focus star" near the intended target, doing a
calibrate on it,

2) focus the camera

3) Then I do the short slew to the main target, and carefully frame
the image. Once the picture is composed, I go to object menu and press
">" which seems to cache the RA/DEC of the current position for later
retrieval.

4) When I'm ready to change filters I slew to the bright star again by
name, and do the filters & focus work.

5) When ready to take photos again, I go to the objects menu and press
"#7 - R/D" which has the coords of my careful framing remembered.

Repeat 4-5 for each filter or photograph series.

I know the easy way to do this is a robofocus and a filter wheel, but
pretend I don't have $1200 for that stuff right now... Am I doing this
repeated change between two sky positions in a silly manner?

Is there any handy software where I can tell it to remember a number
of sky coordinates and just simply click on them A.. B.. A... B... to
go between them?

Thanks!
Mike Clemens
