Howard or Roland,
I will repeat Dean Salman's question of yesterday as there has been no
response. What is the relationship of the Sync in Maxim compared to
AP's Sync versus Recalibrate? Is it safe to use?

Re: Leaving as GTO mount outdoors

Klein, Adam <atk@...>
 

I've been using a StarBubble(tm) 10' (Portable Telescope, Observatroy,
Astronomical and Planetarium Dome) for about 15 months.

Shelter Systems' lightweight, StarBubblestm portable telescope,
observatroy, astronomical and planetarium domes are designed to protect
astronomers and their telescopes from light, wind and dew. The
StarBubbles are freestanding and can be turned or moved easily. They are
constructed with our white/black
<http://www.shelter-systems.com/dome-coverings.html> , light-blocking
covering. This woven, ripstop covering will exclude all light from the
interior of the dome except for the opening for your telescope. We can
make the white out, black in or black out, white in.

The StarBubble(tm) portable telescope, observatroy, astronomical and
planetarium domes line was developed to provide maximum interior space
with a minimum footprint. We have taken our standard StarDome(tm)s
<http://www.shelter-systems.com/star.html> and added an additional band
of poles and covering to the bottom, which creates more height. The
walls actually come in a little at the bottom, like a bubble, so the
diameter at the ground is about a foot less than the widest part of the
dome. This allows you to stand right up against the wall without your
head bumpingit. We have also removed one pole at mid- door section so
that you can walk in without bending. The StarBubble observatory and
planetarium domes has one door.

Two window flaps with velcro closures are provided for your telescope.
The window openings are not cut by us nor are the window flaps
installed. This way you can put them where you need them. We provide you
with the velcro that is backed with sticky tape and two 3' x 3'window
coverings of the White/Black so you can place the windows where you
want. You can also buy extra windows at $25 each.

Hi Rick,

I have been searching the web for a "telescope-only pier housing" for a
couple of years, and this was only one of two that I have been able to
find.
If you can locate any other links PLEASE post them - I really would like
to
build one as well. I saw a wonderful one a few years ago, and have been
scanning the web to get it back, without much luck.

In my situation, I enjoy my lovely garden yard, where the ideal spot for

a small ready made observatory would be in the corner - where all the
fruit
trees block a fair amount of the sky. I am not willing to sacrifice the
trees and ruin the enjoyment of my "day space".

I thought that a less conspicuous pier mounted telescope enclosure would

be a good compromise, with quick access to my set-up, but without a
"building blocking my view" - sort of the large white elephant in the
middle
of my outdoors room.

I really hope you, or anyone else here, can share a link for this
specific
kind of project.

Thanks,
Joe

Sync redefines the relationship between telescope and mount. Recal simply
updates present position and does not redefine the relationship of scope and
mount.

The relationship of scope to mount is normally defined the first time you put
mount and scope together. If you point the scope to a star to the east of the
meridian with the scope placed on the west side of the mount, you have
defined the relationship of scope to mount as being thus: scope always on the top
side of the mount (p.s vice versa works also). However, since this is a German
Equatorial, you can also define the scope to be underneath the mount. The way
you would do this is to place the scope on the east side of the mount, acquire
a star on the east side of the meridian line and do a "Sync". The mount will
now aquire all objects with the scope underneath the mount. If you have a short
enough scope and it clears the pier in all positions, this is not a problem.
However, in 99.99% of the cases, the scope will probably hit the pier, so this
relationship should be avoided.

Therefore, if your external program does not know what side of the meridian
your telescope happens to be in when it issues a "Sync" command, it could very
well redefine the relationship for the scope to be on the wrong side, and all
subsequent slews will attempt to pick up the object with the scope underneath
the mount. For this reason we have a "Recal" command (have had it since day
one!) on our mounts so that a program (any program) can use this command to
update the present position without redefining the scope/mount relationship.

Why don't all programs use this command? Reason is that the "Sync" function
was first used by Meade, and they had no need for a seperate Recal. Why?
Because in a fork mount it is not a problem. One can place the scope on any side of
the fork without the scope running into the pier. GEMs do not work this way.
They can only safely go up to the meridian and must do a meridian flip when
going to objects on the other side. Forks do not have this problem - thus no
seperate Recal is needed.

Bottom line is this: if you KNOW FOR SURE that the object you will issue a
"Sync" command is really truly on the proper side of the meridian line, then it
is ok to use Sync. If you are NOT SURE, or if you are beyond the meridian line
because you were imaging and tracking beyond the meridian, then it is not
safe to use Sync, and you need to issue a Recal. If the program does not have
Recal command, then you are out of luck.

Re: Leaving as GTO mount outdoors O.T.

Patrice Nottingham <gnpnotti@...>
 

Joe,
I'm not sure about lead-acid battery technology or the use of
Lithium Ion or Nickel-Metal Hydride batteries in pure EV but my
Highlander Hybrid (HH) has a warranty on the HSD including batteries
for 150K miles which leads me to believe that I can expect the
batteries to exceed this. The HH and the Volt are designed to keep
the batteries charged between 30-80% or so for battery longevity but I
do not know the charge/discharge scheme for a pure EV. Regardless,
the hang up now is the cost and storage capacity of batteries. I can
recoup the extra for the hybrid technology because I hang onto my
vehicles. I like the fact that I can sit at a stoplight or in bumper-
to-bumper traffic creeping along in the summer and have the AC
blasting and the gas engine off. PHEV seems to be the short term
answer vice waiting for the perfect battery technology or a hydrogen
infrastructure.
It looks like we may be able to get a glimpse of the sky tomorrow
night so I will be able to pull the telescope out of deep storage.

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

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).

Re: Leaving as GTO mount outdoors

Wiggins, Rick
 

Hi Richard,
I think you are correct also. I to remember seeing an article;
however, I think it was many years ago.
Thanks, Rick

Hi Joe,
Thanks. That is similar, but the design that I was describing
only
covers the mount and is much smaller...just big enough to
surround
the mount.

Re: Leaving as GTO mount outdoors

Hi Joe,
I will post if I see them again. They were posted on
the "Observatories" Yahoo group some time ago. However; Remember,
that I siad the design was for mount only...Not scope also. That
would require a much larger case and one that would be more likely
to draw attention.
Thanks, Rick

large scope covers available Re: Leaving as GTO mount outdoors

Wiggins, Rick
 

Hi Richard,
I can add that these are very tough. The best protective cover I
have seen. Industrial!
Thanks, Rick

I have three brand new scope covers I will offer to the first that

these are more of what I had made last year.

they are 144" x 70" (open on the 70" side) and are made of SCRIM
material

this is Mil Spec material as used for protecting sensitive
equipment shipped on-deck on Navy ships to whereever.

here's a link to a webpage that offers more info

http://www.narrowbandimaging.com/scope_bags.htm

I only have three and they are the 70" x 144" size

I've been using these for the last two years.

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?

Mike C
 

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.
Morgan

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


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.


Re: 600E PE "Normal"???

Bob Benamati
 

Thanks, Gilles. Yea, programming did bring it down pretty well and the guider kept up with it rather well.

The scale was right (1.45"/pixel), so the data, I believe, is pretty accurate.

Take care,
Bob

Are you sure your parameters (focal length...) were OK?

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
