Hi Tony,
Thats an excellent video, thanks for sharing it. I have an old AP1200 CP3 which I guess is more similar in size to the 1100. The 1600 sure looks a beast and the improved cable routing looks great.
Cheers,

Set-Up Help Needed

Richard Lapides
 

We moved to Austin, Texas area and really need some help setting
up/aligning our AP 600E GoTo Mount with the AP 155 telescope.
I would be glad to pay anyone experienced and living in Austin area $100
per hour. If you would like more I'm  sure we can work it out.
I built a nice observing deck with a 9" steel pier and adapter and mount
fits on it perfectly - but I forgot all the intricacies in setting up.
Please call or email me anytime. Sincerely, Richard Lapides, home:

Greg, what a great story with a ton of great info!  Polish the whole thing off with such great images is truly an adventure story . Thanks for sharing your saga.   I guess  it’s not too soon to start preparing for 2024 iwhen the eclipse heads just south of Indianapolis. I think the people in Carbondale are getting spoiled .  They are opening up at the Indianapolis motor Speedway which seats a couple hundred thousand for viewing event . Tom Fischer, INdy

Dale,

 

I purchased an AP400GTO through Astromart last spring with the specific intention of using it to support my trip to Wyoming for the August 2017 total eclipse.   When I had asked the same question about portable mounts for the eclipse, the AP400GTO was the mount that several people mentioned.   The sequence for my location and purchase of one was the following.  I put a WANT ad on ASTROMART and after no responses, an AP400GTO popped up as an auction item.  I placed a bid on the auction and when the buyer didn’t get what he wanted for it, he contacted me since I had been the highest bidder and we worked out a sale.  

 

I can tell you about my domestic travel experience with the mount for last year’s total eclipse, although I shipped it rather than include it as baggage on the plane.   It may be more than what you asked for, but it may also be of interest to others.  As a long time reader of the AP and AP-GTO user groups,  I do remember seeing some questions about whether Roland would entertain production of something small and similar to the AP400GTO.   (An AP400GTO successor would be a great match with the new Stowaway!)

 

The mount came to me in a Pelican case that was approx 19 x8 x 17 in (model number is no longer visible).   That case with mount weighed about 35lbs.  It included everything for the mount, including the counterweight shaft, but not the counter weights themselves.   The tripod that I used was the Losmandy lightweight tripod, which was shipped in a separate box along with the counterweights which were well wrapped and taped to prevent movement.   This tripod worked out extremely well – light, adjustable, and a good match for the AP400GTO with an AP105 mounted on it.  (The original wooden tripod that was being sold with the AP mount was replaced with the Losmandy lightweight tripod when the metal fasteners for the legs began to fail when it was being assembled and then disassembled by the seller during testing prior to shipment – it was an excellent substitution and worked well.  However it did require an adapter from AP to mate the mount to the tripod.)

 

Because I was flying out west to spend a full two weeks and had camera gear to boot, I chose to ship the mount via FEDEX ground to relatives in Salt Lake City and then pick it up enroute to Wyoming.   This turned out to be cheaper since most of the airlines now charge $150 for each bag/package beyond the first two bags.    FEDEX ground was about $90 for the mount and about the same for the tripod with counterweights.   I also shipped a Kendrick battery in a small carton and then my AP105 in a larger pelican case on rollers in which I had also placed eyepieces and accessories for the eclipse and for general astrophotography.   For all four pieces, it came to a total of about $340 one way.   (How much insurance you get and whether you request a receipt signature at delivery can affect the total price and YMMV as a result.)  This was expensive, but turned out to be perfect for what I considered to be a once in a lifetime experience.

 

I had upgraded the Mach 1 with a CP4 and, with Howard’s help and for a small fee from AP, repurposed the CP3 to use on the AP400GTO (which originally came with the CP2).   The older keypad was very similar to the current keypad, but the display was very dim in daylight – it required either a towel over your head or a hoodman LCD hood to read the display during midday.  Practice sessions at home before the trip allowed me to work all that out.   (To be safe, I also replaced the battery in the keypad which you order from AP based on keypad serial number.)

 

I used the intervalometer built into my DSLR to control camera exposures (both interval and exposure spread for each interval).   No guiding was required for the eclipse – just level the tripod, accurately adjust the elevation to match your latitude and everything went well when I started from the Park 3 position.   I slewed to the sun (solar filter installed first) and then adjusted with the direction buttons until the Sun was centered using the Televue Sol Searcher and then further adjusted as required to center the Sun in your LCD on the back of the camera while in Live View mode. (Hoodman LCD hood necessary in bright daylight and to allow you to adjust focus.)  I tried to keep it uncomplicated and did not have a laptop involved.

 

Bottom line was that I felt the AP400GTO and Losmandy lightweight tripod  were a perfect combination with the AP105 and for travel in a Toyota Corolla all over Wyoming, Idaho and Utah.  I did leave the large pelican case for the scope and the boxing for the tripod and the power supply at my relatives and repacked all on my return and shipped back the day before I flew out.   I placed the AP105 in the pelican case inside the original fabric carrying case for the AP105 and that fabric case was perfect for the car.

 

But it does seem that you will need the following as a minimum:

-telescope & accessories

-mount

-tripod

-power supply

 

Some lessons learned:

-ship any pelican cases inside their original shipping cardboard box (or fashion one).  Several of those that didn’t and shipped pelican cases directly to the hotel in Wyoming had damage to the cases.  (I now store my pelican cases which are not currently in use in the basement in the box they were shipped in from B&H.)

-practice setup and teardown and solar observing with your mount at home.  Identify what will be different in your actual observing location and store your expected site coordinates using your keypad. This helped me prepare for a great experience.

-practice setup and observing at least the day before the eclipse in the new location (new coordinates and time).   There were a couple quirks involving need to enter the new location, slew to the Sun, return to park, remove power, declutch and put mount physically in Park3 again, repower, and then subsequent slews to the Sun were accurate.  (Although I was still learning AP mounts when I took this on.)

-George was a particularly helpful resource at AP as I worked through all the questions I had about the mount, the scope, and photographic technique as the eclipse approached.

 

Some photos  from the eclipse experience, using the AP105 on the AP400GTO can be found at my Zenfolio gallery:  https://gregvaughn.zenfolio.com/p573603321   (The orange colored photos were taken with a handheld DSLR and telephoto lens using a Thousand Oaks filter.)

 

This has gotten horribly long, but I hope it is helpful.

My latest Daily Build is "TheSkyX Pro DBI Version 10.5.0.exe" dated
6/12/18. This doesn't sound very "daily" to me. Do the contents change
even if the version number and date don't? I have installed that one,

I don't think I've used those buttons -- only the Jog buttons.

No matter.... I can use the AP1200 keypad to center the star in the
finder scope, then do a Recalibrate in SkyX to adjust the mount's sky model.

AP400GTO users out there?

Dale Ghent
 

I plan to commit to some eclipse-chasing over the next years pretty much until I'm unable to do so anymore. Especially for remote places, I'd like to bring along a german equatorial goto mount which would be suitable for hefting a refractor of <= 100mm in size. Obviously, the eq mount and its attendant tripod would need to be airline portable. While I already have a quite mobile Mach1, it's not something that I would consider to be airline-portable and certainly not internationally where weight and size restrictions tend to be lower compared to US domestic flights.

This brings me to the long-since out of production AP 400GTO. One will pop up for sale now and then and it realized that it appears to be quite an ideal size and weight for airline travel, and a suitable tripod for it could conceptually be able to fit in a hard case such as those used for transporting skis. Are there any AP 400GTO users here who might be able to relate any experience with traveling with this mount? If necessary, are the RA and DEC halves detachable like they are on later AP designs?

TIA

I don't have a 1600, but if you're generally looking for brands as an alternative to Pelican, you can see if Nanuk/PLASTICASE (a Canadian case company) has anything that you might find suitable for your needs.

Crystal clear (as I wish my sky was). Thank you very much. No need to use the TSC jog buttons, since I'll have the keypad in my hand as I peer into the finder scope.

I don't have a 1600, but if you're generally looking for brands as an alternative to Pelican, you can see if Nanuk/PLASTICASE (a Canadian case company) has anything that you might find suitable for your needs.

One followup question.... If I use the AP1200 GTO keypad to center a target, then do a Recalibrate in the TheSkyX, will that update the AP1200's sky model? Or must I use the SkyX Jog controls if the mount is controlled by SkyX?

The way the mount is controlled, an application (SkyX) sends a "Move"
command and then a "Quit-Move" command to stop the move when you let go
of the button. If the "Quit-Move" is not sent, or gets lost because of
bad connection from your computer to mount, then the mount will continue
to move as instructed. You might check your USB cable for bad connection.
The interface is RS-232 serial, not USB, but I'll check the connectors.

To me, it seems more likely TheSkyX is doing something bad, since the mount moved WEST (right) after an EAST (left) jog completed.

I'll post on the SkyX forum and see if anyone there can explain this odd behavior.

Thanks, Rolando.

Hi Tony,
 
    Just curious ... why you want to spend more $$$ for specifically a “WATERPROOF” case. There isn’t much that can get water logged, the motors should be well sealed themselves, even if the mount drops into a lake ! After all, the mount stands out there, dripping wet. at the end of a dewy night.
 
    On the other hand ... the CP4 controller is an entire different story – early models don’t swim well, and their electronics could drown just on a night of heavy dew.
Much easier to remove the controller and put it in a ZIP lock sandwich bag, then into a pocket or normal luggage case, when travelling.
 
    Otherwise, a standard mount case,  will do fine, at lower cost. AP has some to offer.
I would go for a PELICAN, perhaps a model 1640, or maybe the slightly smaller 1620 might do if you check internal dimensions. These aren’t all that lightweight (40 lbs ?), so the luggage wheels and handle are really a necessity with the added weight of the mount, cwts. bar etc.,
 
Joe

A pair of Pelican 1660's will work.

Just FYI, Pelican cases are NOT waterproof.

The kind with air pressure equalization vents on them will allow water into
the case if there is water on the outside of the vent.

And all it takes is a single hair across the lid gasket to disqualify it as
waterproof. And some models have screws that go through the case wall to
attach telescoping handles.

However they are very water-resistant.

Here in Hawaii, I always add a reusable desiccant pack with my gear in my
Pelican cases.

Lately I have become a big fan of Pelican's AIR cases. I just wish they had
them in as many big sizes as their regular cases.

I am also now a big fan of their Trek Pack partitioning system.

Subject: [ap-gto] waterproof case for 1600 mount

Just wanted to see what you guys are using for a waterproof case for the
Dec. & RA axes for the 1600 mount. It would be for storage in the home and
while moving it in my vehicle, not for airline travel.

I am only interested in the Pelican or Storm type WATERPROOF cases. Can be
some other companies waterproof case also as I am not aware of every company
out there. If you can also email me pictures of how they fit in your case so
much the better ( my email: astrocnc@... )

Thanks for your input.

tony
