Thanks Stuart. I must admit that it is a lifesaver for me given the
low QE of the ST-2k especially in the red. I use double luminance
layering and it seems to work for me quite well.

Thanks to Gilles also for his comments.

Dear group,

In a mad rush to beat the arrival of the full moon shortly, I sat down
last night to pursue the PacMan Nebula in Cassiopeia. For the result
based on over 5 hrs total exposure (RRGB @ 200:60:60:60), I kindly
direct you to http://www.perseus.gr/Astro-DSO-NGC-0281.htm .

Clear skies!

What I do in PEMPro V2's polar alignment feature is I let the user select a star
(any star) and I show them the direction that the star should be moved. You can
then toggle between the current position and original position.

As a future feature I'm planning to add sound effects so that as you adjust the
mount closer PEMPro will beep faster and higher pitched until you reach the
correct position. This allows you to make the adjustments right at the mount
without having to go back and forth from the PC.

Yep, I use the full crosshairs align on PAM as well, but it's tricky
if your initial pointing is bad enough that the bright star you're
supposed to be centering starts off screen.
There's no directional indicator of which way you're supposed to be
moving the stars on screen, plus you've no way of knowing if you
overshoot.
Tricky problems, but not insurmountable - they could add a "platesolve
now" button which updated the movement instructions to give you an
idea of how much further you have to move.

I just discovered something cool

I am using the baader narrowband set on the ap180edt f/9 right now. first time to use them on anything but the pentax 6x7 lenses (150, 200, 300mm so far)

anyway on the big apo i found that they are parfocal!

so on a well color corrected scope, the filters are parfocal at 673, 656, and 500nm wavelengths

that's a nice and unexpected benefit!

it sure takes time to test gear though: you get all set up to use one configuration and then hate to switch to something else: halfway through a multi-night image etc: once I get on a roll shooting images with one system configuration I tend to stick with it for a while. Anyway it is nice to get to use the filters on the big apo. Hopefully I will have some results to show pretty soon.

If you need to know the bolt length, let me know and I'll pull one
out.

I assume you can do similar with the Mach 1.

Thanks, we'll have to look into that.

Re: Help with RS232 to USB cable

Paul <plefevre@...>
 

Hi Tom,
Here's a web page that may help:

http://www.usbgear.com/USB-Serial.html

More options than you'll ever want, probably :)
I use their USB to 2-serial-port adapter...one goes to the AP mount,
one to my RoboFocus (#USGB-2X232 on that page). The serial cables
from the adapter can basically be as long as you want them to be, mine
are both 12 feet. It very reliably runs my mount and focuser, and is
$40. Lots of other less expensive options that work well.

As the subject implies, I'm looking for a ~4-5 meter adapter cable
between the mount and USB computer port. I know I saw some traffic
on
this (Possible future AP product?) but darned if I can find it again.
IIRC, the key was a type/brand of chip in the cable????

Forgive my poor search skills...
