Thanks for the quick response- appreciate it.

Not critical in your case. Rolando

I have an AP1100 in a permanent observatory on top of my garage parked in position 4. During the past 3 years, I've only imaged about 120 hrs per year. I read in the manual to use the keypad to move

> have an ATIK 16200 with an EFW3 FW. I ordered the TV NP101is Field Flattener (LCL-1069), which per TV has a recommended Back Focus of 2.75" (69.85mm) for the ATIK 16200 34.6mm diagonal sensor.

The attached image was just a test shot during flattener collimation. Not the best processing etc., and was shot in my bortle 8 / 2" + sky. It's to illustrate how fast CMOS cameras can be. 37 subs@

It's a different world with CMOS sensors. I've been shooting CCD's for 20 years and CMOS for about 1 1/2 years. Fast computers mounted on the telescope, SSD drives, lots of disk space etc. Learning

Hi Don. I read your post with interest. What set me down the path to finally get a definitive answer to how to calculate the Back Focus with Filters is that I just acquired an TV NP101is OTA, the

The AP hand controller sends NO signals. It is totally silent unless you, the user, pushes any of the buttons. Roland

Hi Tony There was something else I noticed in your video that got my attention. Your counterweights have the bronze inserts in them. Are these older counterweights, or did you get them with your Mach

Hi Roland 359 MB per image !? Wow ! I guess that the image size must go up exponentially with the number of pixels. The images from my old 2.7 megapixel camera are something like 1.9 MB. From my 16

Just FYI, I used TSX with my 1100 (no encoders) for years. When I added my Mach2 (with AE of course) and set up for remote imaging I quickly learned that TSX was (1) unnecessary and (2) created a

Thx

AAP guiding is frustrating ..I find that I literally must unplug my AP hand controller from the CP4 - as BOTH AAP and the hand controller are send tracking signals ... no kidding. I also have set my

Hello Andrew I have been following your thread on this with interest since I went through this exercise some years ago when setting up my imaging train on my Tele Vue NP127is refractor. The concepts

Hi Liam, Oops, got it figured out. I read where TheSky X had drivers for the 1100GTO, so I didn’t select TeleAPI selection, selected com port 5 (virtual), and corrected the time on my computer to

I use Cartes du Ciel (CdC) for GoTo. CdC integrates well with ASCOM to A-P ASCOM Driver and APCC. With CdC, I use a similar process to Roland for centering elsewhere from the desired object.
