Hello to All, I'm new to the ap 900 mount and astronomy. Mount works fine, but I now want to utilized the remote control software of my laptop. The laptop will be approximately 100ft away from

I am having trouble adjusting the altitude knob on my mount, yhe set screw is weak and while turning it to raise the scope the set screw slips off the flat area of the threaded shaft. I have tightened

I guess you can argue in all directions on this subject. My initial thought remains the same, regardless of drizzling and deconvolution. If you match the size of the pixel to the size of the Airy

an F2.5 Well it depends what you are trying to optimize as well as how well the optical system performs. Take the Tak Epsilon 180 I mentioned, the f/2.8 speed should match well with a ~3.75 micron

Hey Jeff, I also use Bluetooth on my AP1200GTO and with the help of Howard from AP he sent me the pinout of Com port 1 and Com port 2 and I can say without a doubt the Bluetooth adapter will

Hi Dave, Thanks, glad you like it. A scope without limits ... that simple. It really makes each and every session a real joy and it puts the fun back into astronomy and astrophotography. On one

Hi Anthony, Wow, that's a sweet image of M13. Great work! Don't you just love imaging with the AP 160? Since I've had mine I hardly use any of my other scopes. Best Regards, Dave

'scuse me for butting in (late as usual) - and I do know this is off topic ... The f/ratio myth is something that has confused me also. We know that the f/ratio is certainly not a myth for any land

Hi Dennis, I use ACP while imaging and, depending on what ACP's doing, tracking might be turned on and off a number of times over the course of a night. This has never affected the pointing of my

Thanks Neil. Glad you like it. Anthony.

AP1200 GTO. The other day I was focusing my re-installed guide camera on a truck stop sign a few miles away and had the mount tracking set to Stop. I used the keypad to center my terestrial target.
