Re: Appropriate dec backlash setting?

brian_clever <brian_clever@...>
 

Roland, thank you kindly. I had never heard of such a thing but once
I went through the procedure on the AP website my tracking is
looking much much better with DEC set to 1. Thanks again!

Brian C.

Hello friends. I'm getting my AP900 with 12" LX200R tuned up
nicely finally. I found that setting my dec backlash to 7
achieved the best results.
That is very high and indicates that you need to put the Dec worm
into mesh.
You should also check to make sure that the final spurgear is tight
on the
worm shaft and is not rotating slightly when it reverses. If it id
not tight,
then tighten the setscrew that holds it onto the worm shaft.

Re: Advice please: Standard verus Rotating Pier Adapter

Joe Zeglinski
 

Good point, Kent.

I had forgotten about the side screws - AP warns against our even touching
them.

I was considering drilling a hole for a locking set screw - about half
inch inward from the gap of one or both azimuth "adjuster knob housing", on
the RPA. That way, I couldn't simply move the selected fixed one, ruining the
careful setting without thinking, as I replace the mount base and retighten
the opposing adjuster.

now.
So if there is any minute ground shift over the short year or two, the RPA
should give me less hassle in minor very precise, alignment touch ups.

Joe:
One possible problem with the RPA.
There is no 'real lock' in azimuth.
If you adjust azimuth in one direction using one knob and acheive the
position you want, should you move that knob again, the adjustment will be
lost. I
suggest that once the position you want is reached, to carefully tighten the
opposing knob up to the adjuster post.

Another possibility is to completely tighten the resistance adjusting scews
(2) on the outside edge of the RPA. These are usually used to adjust the
tension of the rotation of the top plate, but I'm guessing one could tighten
them
all the way, preventing the top plate (and mount) from moving.

Joe:
I believe the Revolving Pier Adapter was produced primarily for those who
don't have a permanent pier and set up and tear down, either in their own
yards
or some remote site. While the original standard pier adapter works great,
when
doing polar alignment, loosening and tightening the 4 screws can slightly
shift the alignment. With the RPA, this doesn't happen, making polar alignment
less time consuming.

Re: Re-run Made in America segment with Astro-Physics

Hi Rick,

Whose site was the FTP download link? The stations or this group's, an in
what section (Files, Photo)?
Anyway, I did a general search on "Ratzenberger", and saw all the messages of
many others wanting to see the program, but having no access to the US TV
channel. Interesting "legality" discussions, as well. I wonder, if a copy were
on the AP install CD, if that could be considered "private viewing" to pass
legal muster.

I guess I am out of luck of seeing it, otherwise. Oh well, maybe the flic
wasn't that big a deal, after all.

Re: Keypad problem ?

Joe Zeglinski
 

Czesc Dominik,
Jak sie masz?

Just as a side note on most "elastomer keypads" (like those on your TV
remote) in general.
I don't know if this is the same type as inside the AP keypad, though.

I have found that the rubber membrane on a "typical electronics product
keypad" leaches out some kind of oil as the years go by, probably more if the
push buttons are used very often, like "TV channel surfing". I suspect this is
the embedded "rubber mould, release agent", that remains behind in the rubber
during manufacture, and slowly comes to the surface. Surprisingly, the oil
film on the PCB, seemed about 1/16 inch thick! Quite a puddle, not just a
film. There is no way that the carbon bump under the rubber button could make
electrical contact with the etched copper pattern under it, through that much
oil. I have now repaired my old Jerrold TV remote keypad about 3 times, and a
few others for relatives, simply by taking the case apart, and washing both
the rubber sheet and the matching contacts on the circuit board. I just poured
the Palmolive soap on the PCB, dunked the circuit board in the sink, and
gently scrubbed off the oil in the mild sudsy dish washing soap (NOT dish
washer detergent). On one unit, I tried, (unsuccessfully), just spraying the
PCB with Windex, Isopropyl alcohol, or similar degreaser, but this scum
requires a bit of rubbing with a good soap to make the contacts work longer.
The keypad worked fine for another couple of years, or more, before my
favourite button (channel skip) leaked out more oil, and another washing.

By the way, the oil wasn't from kitchen cooking grease in the air, since
the TV remote pad was always in the living room, and certainly hand oils can't
leak through a full, solid rubber, sheet of buttons - so there seems to be no
external source of this thick oil cover, other than the rubber membrane
material itself.

Mind you, such home remedies may be frowned upon by the manufacturer -
especially dunking the PCB in water - but since I was going to toss it away,
I took a chance and continue using my original controller for many years. The
water didn't affect the electronics after drying (isopropyl spray like
eyeglass cleaner, might be a good final cleanup of any possibly remaining
soap).
Home repair is better than recycling.

By the way - the AP Hand Pad has a 3 year warranty, so don't try the above
home remedy, until it has expired, and you aren't sending it in for
professional repair.

I'm curious, Dominik, when you took the AP keypad apart, how clean was the
PCB surface, and how old is your unit? I can't imagine why there was a "trace"
needing repair, or how it might have been damaged. That is a quality concern.
I wonder if the PCB can't take a lot of push button flexing, in the cold.

Thanks,
Joe

The mount has a clutch, so if you do not tighten the clutch to its maximum,
the axis will stop as the gear continues to rotate. If you have a lot of
unbalance in your scope, then of course you will need to tighten the clutches to
their maximum, and this will not allow them to slip should the mount encounter a
hard stop.

Re: Safety Limits

Sure would be nice if software programs had a Table of DEC angles versus
Safety Limits. That way, we wouldn't have to worry about the scope or
equipment striking the pier. The software would know the current DEC and
adjust the safety limit dynamically using the table.

Just a thought.

is in the manual, only safety limit of 0-20 degrees before the meridian.

I have used the timer on PulseGuide but I was wondering if there was
another way.

Thanks,
Tom

Safety Limits

Tom Davis
 

One thing that I love about my 1200GTO is that I can image far past
the meridian without having to do a meridian flip. I do have concern,
however, that I might go too far and some night strike my pier. Is
their a way to set a safety limit (past the meridian) so that if that
point is reached the mount stops, or flips, safely? I can't find this
is in the manual, only safety limit of 0-20 degrees before the meridian.

I have used the timer on PulseGuide but I was wondering if there was
another way.

Thanks,
Tom

C/2007 E1 (Garradd)

Dennis Persyk <dpersyk@...>
 

This comet is ideally positioned for imaging from the Midwest USA as
it high (57 degrees elevation) and transits at a "reasonable" hour –
that is, at astronomical darkness. At magnitude 13.0 it is an easy
target.

It has a relatively fast motion relative to the star field, 6.2 arc
seconds per minute. I imaged it in one-minute frames with at 5.0
arc seconds per pixel.

The fast relative motion lends itself to a nice animated GIF. I have
a small (422 kB) video of 1 hour of the comet traversing 6.2 arc
minutes of Leo. Take a look. The comet is really racing along!

This is my first image of 2007. I've been spending time on another
hobby – an indoor, non-weather-dependent hobby <G>. See

Thank you for visiting my site.

Re: Mach 1 GTO load capacity

Bob Holzer <b.holzer@...>
 

Hi Bruce:

I have no idea about the load ability, but the resolution is a
wide-field 3.5 asp so you won't need much tracking accuracy. Sounds
like it should work fine to me.

Weight won't change the tracking accuracy. It is more a matter of
stability
in the wind with heavy weights and large tubes catching the breeze.


I'm dreaming of a SMALLER set-up than I have right now to include
a uhhh mmm Takahaachoo E 180 ED and IMG 6303 cam with 78 mm guide
scope...pretty compact but with rings,plates, cams..
is about 55 lbs.
Won't really know until you try it. For that you would need to come
over and
bring the equipment.

Thanks for posting these images. If it's clear I might try imaging this
object in the next couple days.
