Hi Roland,
Can you refresh my memory....what major upgrades are going to be
offered in the new keypad software??

Thanks,

I'd love to use the new keypad software during the summer star party.
Any news would be appreciated.

Thanks,

Thank you Roland. Certainly, the clutch knobs were pretty tight (by
hand, not wrench). I'll check the plugs.

Your clutch knobs may have been overtightened and the clutch plugs
are now

Hello group,
Here's my latest image of M27 with my C8/1200GTO/ST8XE
setup... http://www.markles.com/outbox/Mike/rrgbm27mail.jpg

It was taken at prime( f10 ) and was an rrgb exposure.

R(lum)=12x10min unbinned
R=3x10min binned 2x
G=3x10min binned 2x
B=4x10min binned 2x

Enjoy,
Mike

Subject: [ap-gto] Pelican nebula and way too much time on my hands


Hi all,
While experimenting with my UV blocking filter, I realized that I had
accumulated lots and lots of exposure of the head of the pelican, more
than
8 hours of light and about 2 hours of darks. During the course of the
experiment I have concluded the following for my setup of a Takahashi FS
128
and AP 900 mount:

- A UV blocking filter really helps, but the Optec filter with a cutoff of
435 nm is a bit much, so I will be looking for something a bit less
aggressive in the blue
- An IR blocking filter for the L images helps preserve the sharpness of
the
stars and is well worth the sacrifice in light, just expose longer
- The AP 900 is great for experiments like this, allowing for long guide
integrations for the blue exposures and still providing excellent tracking
- 8 hours is way too much for one object, could have also imaged something
else for 4 hours and still had a decent Pelican head

Thanks to Don Goldman for explaining Rob Gendlers LLRGB combining
technique.
Really helped presevere the L data

Here it is, all de-bloomed and everything. Also, thanks to the UV blocking
filter, no adjustments were made for blue halos. Hooray!

Re: ST237 and AP900GTO

Can anyone explain this behavior with the ST237? Alan explained that
relays are not used in the ST237. I had thought that maybe with power
off the relays were normally closed but that discards that theory.
This camera uses an open collector output to pull down the 4 control lines
when any of the switches is activated. No doubt, the outputs also have transorbs
or collector diodes attached to the 5 volt power to prevent lightning or
static charges from destroying the transistor collectors. When the power is
removed, I'm betting that these diodes now reverse-conduct to ground as the 5 volts
collapses to zero, thus enabling both RA and Dec axes on the mount.

With cameras like this, you will have to remove the guider cable when power
is removed. This would be an issue with any mount set up in remote mode where
power could be applied or removed to the various instruments.

AP 1200 QMD and Meade 16"

thefamily90 Phillips
 

I am considering a large aperture S-C as a compliment to my
refractors for visual observations of Deep Sky. I do not want a large
Dob. I have an AP 1200 QMD mount. A 14" seems like no problem at all
for this mount. But, would it hold a 16" Meade? Anyone have any
experience? Thanks for any thoughts.

Jim


Re: AP 1200 QMD and Meade 16"

paulatkinson22@...
 

Jim,

You will be right at the weight threshold of the 1200. According to Meade
the 16 OTA weighs 120lbs. when I contacted them. I had been contemplating the
same thing you are at one time.

C14 meets M27 on an AP900GT0 at 3910mm

Back from a little astrophoto trip to central Oregon. Seeing was pretty
good, but it took 5 days to image because of variable transparency caused by
a badly placed forest fire.

The mount was borrowed... My 900 arrives tomorrow... I can hear the mount
begging for mercy already! <g>

THERE WILL BE NO MERCY!

However, you cannot unlock the clamps and manually slew the scope. You have to use the motors to move the scope.

Thanks Roland,
The ADS database is excellent and I do use it. But occasionally I
like to observe a more detailed list. Your suggestion will be a
great help. thanks!

Jim


I see that you can put in
coordinates for an unlisted double and it will slew to it. But,
is
there a way to display the RA and DEC coordinates and slew to
doubles by reading the coordinates as you slew?
If you have any of the version 3 software installed on the keypad,
simply go
to the Objects menu, press the > button and you will see the RA
and Dec
co-ordinates of your current position displayed.

You can also find doubles uing the ADS ouble star catalog in the
keypad. Go
to the double star catalog by pressing the # 6 = More button.

Re: Finding doubles with GOTO

Hi Steve,
I do not have TheSky. Perhaps I should consider that. What I'm
interested in doing is going down the list of doubles in a
constellation using the chart in The Deep Sky Observer's Guide (or
using the 2000 coordinates in the back of Webb's Celestial Objects
for Common Telescopes). Thanks for your thoughts.

Jim


Jim,

If you have TheSky, link your telescope to the program and use the
Digital setting circles under telescopes. This will put the display
on
your computer screen.

This is probably a dumb question and I apologize if so. I had a
1200
QMD mount, which I used for finding double stars. It was connected
to an NGC-Max. By using the "display coordinates" key I could move
the scope by hand to doubles on a list by coordinates. I have
replaced the QMD with a QOTO mount. I see that you can put in
coordinates for an unlisted double and it will slew to it. But, is
there a way to display the RA and DEC coordinates and slew to
doubles by reading the coordinates as you slew? This would allow
you
to go down a list of doubles in a small area of the sky without
having to type in the new coordinate each time. Thanks very much
for
any help.
