My understanding is that the MinMo parameter is hard coded to be 0.25 pixels on the AAP. If you are using a guide scope instead of an off-axis guider, you might have an +/- 1 arcsec (or more) of

Thanks for posting John. Very nice image. Even taken in a fairly light polluted environment it came out well. Images like this make the decision to move away from a OSC camera more difficult. Glad

Is there a link where we can see the image? --- Mike

You are correct Mike. They are the older design CW's. tony

The following is my post to our clubs Facebook page. (Texas Astronomical Society of Dallas) An example of fairly fast image acquisition with a OSC CMOS camera. I'm trying to get efficient with my time

There is only one way that the keypad can override external instructions: If you have the keypad guide rate set to 1x sidereal but have an external guider set at some lower rate, then if you use the

The keypad does not send anything to the mount during guiding, nor does it modify any outside commands sent to the mount, whether they be slewing or guiding commands, regardless of what app is sending

Thanks Roland, I made that errant "assumption" because I observed the AAP guiding program was sending corrections double the necessary "pulse" to the mount - and I had already backed off the pulse

Hi Linwood. I was also concerned about the 2.75" vs. 2.67" back focus and which one I should use. I called Tele Vue and talked with David and asked him which number I should use for a KAF-16200 sensor

Great post John, thanks for the perspective. TJF Mobile

No problem PM me anytime. Do you need my email address? Don Anderson

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
