Re: help please - various items

Jeff Young <jey@...>
 

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

I am a new user of AstroPhysics coming from the Vixen SS2KPC
stable.
The first time I switched on the unit (not having studied the
manual at all
well) is seemed to go OK as it did the second time. Each time I
had just
switched off, then before restarting loosened the clutches and
put
telescope to the pole (I am in the S. Hemisphere). The third
time I could
not get it to do anything and had to resort to phoning a
colleague in UK
who has an AP. He told me how to unpark it, (I had not parked
it) which I
did and it then went. I then read the manual and concluded that
it was
impossible to work the mount except by first "unparking". Also
that before
switch off one must "park". So far OK.Now for the problems for
which I
need help please......

1. In using some of the polar Alignment programs it is necessary
to stop
the tracking temporarily then restart it. I can find no way of
doing this in
the manual. Howard explained to me, very thoroughly, that the
stop button
onlly stops slewing but does not affect the tracking. How can I
stop/restart
tracking withpout switching off the mount ?

2. If I switch off (accidentally or power failure) how do I
resume use,
preferably
at the same spot ?


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...

PEMPro gave a +/- 25" error--which stunned me... It does seem that

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.

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.

Re: is this a sane workflow?

Roland Christen
 

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.

I use the ones made by I/O gear and they seem to work with no issues. You do
need to find the com ports and make sure they agree with the software. I
have used an edgeport in the past and it is good because on USB cable can
contain several different interfaces. I like the 2 COM and 4 USB port box
since you get 2 coms ports one for the mount and one for the focuser. USB
for the camera and you are set and only one cable to connect to the laptop..

In my case, they sent an "expert" who validated the costs I specified in the Excel

serial number).

These photos are also printed in the policy.

Re: Insurance for astronomy equipment

HI there,

I have all of my astro toys fully insured with AIG ... they are supposedly the biggest
insurance company in the world with offices and branches all over the globe.

They did not have the slightest hesitation about insuring my expensive equipment ... and
that includes everything with a value of $300 or more. They also took photos of invoices,
customs forms etc for their records.

My only disappointment is that they converted the value of each piece of equipment to
euros and then used that as a basis for getting me the final policy cost (in addition to the
house, furniture etc). This I did not like since I could be underinsured if the USD improves
to 1.20 or better (against the euro). Of course, right now, I am overinsured and this is
something I can obviously live with should something catastrophic happen to my astro
gear.

Thanks,

Maybe that is where I saw it, in the middle of a lovely backyard garden, or brick patio. I can almost still picture it - I think it housed an LX-10? I do believe I scanned my back issues of S&T a while back, but struck out. I will have another look, just in case. Sure wish S&T's indexing site was a lot easier to use - or that they would bring back the semi annual printed index that some fool discontinued a couple of years ago - I have the feeling the magazine is in decline, and am considering discontinuing, after over 40 years of subscribing.

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

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

Re: Leaving as GTO mount outdoors

Hi Morgan,

Sounds great - but as for the "gate", maybe you can form the wall into a spiral (even an offset square), so the entrance is open, still hidden, but doesn't need a latched gate to handle in the dark, unless you want to keep the larger critters out of the enclosure.

The round paved walkway - leaves me to imagining a "yellow brick road" - narrowing as you enter the green observatory, for the local school "Munchkins " to come and observe the sky. Have you considered yellow bricks :-)

You are planning a "4-foot deep" footing, just for tripod legs? I was planning to bury some stone cinder blocks below grass grade, and silicone seal onto them, a set of Losmandy tripod vibration pads (which have suitably molded slots for those angled pipes), so I can just slip them in like feet into a pair of slippers. That would be a permanently repeatable position for my portable tripod set up in the yard, with anti vibration isolation from the stone surface as a bonus.

As for gravel - I stay away from gravel parking lots, at the club dark sites, because of the clay dust, and the dirt picked up on shoes and knees, not to mention stones. One night after just a few hours of observing at our dark site, in an area of gravel pit mining (during the week), I was shocked to see a large glob of clay dripped down the meniscus of my Q7 corrector, after the frost had melted and collected clay particles deposited on the lens, just from the surrounding air. There wasn't even a breeze to account for that deposition. Learned my lesson about dirty clay.

There are "pots of annuals" I was thinking about using in a circle around my spot. I forget the name of the small plant, but it smells of lemon, as a mosquito repellant. Unfortunately, a dozen pots of this annual plant, every year, can be expensive, but I will look into it.

Joe

Arborvitae is the type of evergreen I'm going to use, if you google it
you'll see an image. They're nice and dense, can be bought at the
right height (about 6') and when planted about 2' apart, give a strong
privacy hedge. I'm planning to make an enclosure about 9 x 9 feet on
the inside (unlike a building, I can always trim the walls back a bit
if needed...) and with a good solid gate in a sidewall opening that I
can lock to keep curious kids and critters out. I'm thinking that I'll
plant either grass or a low mossy-type ground cover, have a nice paved
walk to the entrance and a little paved pad inside for a computer cart
I'll wheel in when using the scope. The scope will be on a tripod with
4' deep footings - less intrusive and permanent than a big slab for
the 1200 mount on a pier. I plan a round paved walkway for viewing,
with gravel under the tripod legs and the scope and tripod covered
with Telegizmos 365 covers. Should work well, and look good too.
Money saved from building a remote observatory should buy me a Prius...
