Re: Mach1 and checking PASILL4 results

Dean S
 

Hi Pierre,

I managed to check the polar alignment scope tonight. After my drift
alignment with Pempro, the polar scope is perfectly aligned with all 3
stars.

What was unusual is, that when I looked thru the polar scope, it was
perfectly aligned without me even touching it. I doubt that would happen
very often.

Hi Pierre,

Last night I got some time to test my new Mach1GTO. I aligned it with the
same polar scope I use with my 1200. My targets where on the chip after
my
first star synch, not perfect but very close.

Then I did about 45 minutes of guided images, what a smooth graph!
Perhaps
better than my 1200 even? Well only because I was guiding at a much
smaller
image scale really. But regardless it guided extremely well, so good in
fact I see little need to drift any more, at least when I am imaging at
2.44
arcsec image scale.

Then I went to Pempro and checked the polar alignment. On azimuth it was
off at about 2.3 arc minutes. I adjusted until I got it about 0.5 which
seeing was bad so that is probably best I could do then.

Then went to check Dec and it said it was off about 6.0 arcminutes. I
adjusted and went back to Azimuth which was then off a bit and readjusted
just little back to about 0.5.

Unfortunately clouds or fog was making Polaris hard to see at this point
so
I could not check the polar scope but will do so tonight

Anyways I will be happy with only the polar scope alignment for the most
part unless I need to do longer exposures at longer F/L.

Hi,

good news for you ! I rechecked mine again yesterday (got a few hours
before clouds rolled in) and same result: align with polar scope
only, check with PoleAlignMax => 10 arcminutes error.

Which mount did you check it on ?
I'll be interested in your future feedback on your Mach1, although I
am convinced that the mount is not the trouble; I suspect my
polarscope is (or I am missing something but honestly, no clue).
My next plan is to check on a friend's 900GTO, when he is available
for a test ... and the weather clears up...

Re: Getting hot

Hi Dean,
I had mine in the desert last year when the temps hit 115F. I had it
under the silver scope cover from TeleGizmos. This keeps it relatively
cool as it reflects the heat.

Re: Meade tripod - wedge bolt hole pattern

I believe this might be what you are looking for:

http://www.pierplates.com/AP%20900%20to%20PierTopPlate.pdf

I had my 900 pier adapter modified in this way. I'm not sure
whether you have a permanent pier installation, but note that the
countersunk holes for attaching the 900 pier adapter to your pier
top plate will interfere with the tapped holes for mounting the RA
axis to the 900 pier adapter unless you can rotate your pier top
plate away from north by at least 7 degrees.

Hello Larry,
for as much as my opinion counts, I don't see any reason why you shouldn't
use the full version since you have it.
The AP version is a reduced version of the one you have and it was
SPECIFICALLY and ONLY for AP mounts. The full version applies to most mounts
and has features that the AP doesn't have, such as the polar align wizard.
I believe that Ray will reply to you, but I'm quite sure his answer won't be
different from mine.

Well Ray,
after installing the latest version, I started all over again and
successfully created and uploaded to my 1200 a very good curve that
virtually eliminated the effects of PE. Before I could go unguided for no
more then 2 minutes (at 1250mm focal length). After uploading the curve I
tried a 5 minute exposure and the outcome was perfectly round stars all over
the field!

Thanks Ray for your assistance and help.

Re: Power light and switch

Dean --

A wire attached to the servo controller will act as a bit of an antennae
for static discharge from a nearby lightning strike -- whether or not
it's plugged into anything. If you live in an area that gets any
lightning at all, you're better off disconnecting the power cord from
the mount.

At least that's how I understand it. I'm certainly no expert on the
subject....

Re: Power light and switch

Dean Salman <cluster@...>
 

I am going to buy another cable and do just that. Just make sure
that cigarette lighter plug is in all the way or you are really going
to be in for a big suprise when you connect it to the battery. Maybe
the AC/DC boxes are better built than a simple radio shack adaptor
that goes from cigarette lighter to the two clips. Still think AP
should offer a power cable with clips on it in addition to the
other. Anyone that has an AP mount should have a backup power cable
and if they are battery powered anytime, a direct connect is always
better. I have backup Y cables as well because if those go at a star
party, your toast.

The switch idea won't work because you need to see if the red light
is red first before you turn on the rest, so I take that suggestion
back.


BTW, I really suggest Pulus-Guide if you anyone is not using it. If
your pointing is not the way it should be, bad power will prevent the
RA/DEC from being updated correctly. In the case I dealt with this
weekend, after the slew the RA/DEC were the exact same as before the
Slew. PulseGuide from I understand is the only way to get the
current RA/DEC the mount is at.

Power light and switch

Dean Salman <cluster@...>
 

I have a couple of issues to suggest as a future change and upgrade.

Friday night I was imaging with someone whos AP 1200 was not sounding
right when it was moving, sounded sick really. Using PulseGuide, I
noticed as the RA and DEC was moving, the getting RA and DEC was not
moving. This would explain why after parking the scope to park 1,
doing the same command tried to park the scope again by moving it
into the peir. It turned out that his power cable had some kind of
issue. However the power light through all this was red. So what
good is the power light when the mount did not have enough power to
operate correctly.

Here is the upgrade part.
Since I had to give my friend my power supply since he did not have
the right connector for my cable (long story there), I used battry.
However, you have a diffrent connector than what you can attach to a
battery. When I used the radio shack adator and connected to the
battery, my mount went crazy and had the yellow light. It turned out
that I just did not have the power cable pushed in enough.

My point is that the yellow light did come on. You need an Off and
On switch so that when I do get a red light, I can turn on the
swicth. Having a swicth is not an old subject, I have heard this
complait before. maybe the run you are planning this, but you should
offer an upgrade fro current users if so.

Howard, more problem at the Inn. The AP mount now runs forever as it
someone is pressing the keypad buttons all the time, so it runs
wild. So I plan to call you today about this one.
