The clutch settings have no impact on the backlash in Dec. How much backlash do you see and how are you measuring it? Rolando

I need to get pack to Park 3 position but the mount will not when the #3 button of the keypad is pushed. How do I do this? I tried disengaging the clutches and letting the both axes go through the

Hello, Long time listener, first-time caller here. My name is Derrick Siebert and I recently acquired a used Mach 1 mount with a upgraded cp4 computer. I am mounting a stowaway to the mount and I

🙂 Yes, I decided to go ahead and do the upgrade and placed my order. I posted the CP3 on Astromart and it already sold. It will be nice to have both mounts on CP4.

Yeah the QSI cameras are great. I had a few of the Sony chipped ones. The 6120 and 690.

Benefits: 1) Sell CP3 if you get CP4 2) Better resale value if mount is equipped with CP4 3) I really like using Ethernet Peter

It's a really nice camera with a compact 7 position filter wheel. My filters are Astrodon which produce no halos around bright stars and are basically perfect. Mechanically it is robust and it works

Well, it's the overseas shipping that's the biggest nuisance. When I bought the camera, I had spent a lot of time talking to Kevin Nelson, then of QSI, and I was comforted by the availability of

Ahhh okay. I'm slow today. I've heard getting service from QSI now takes an extremely long time...

Bill: I was replying to Rolando's "ouch."

Tom, That is the first generation keypad. It will not be able to be updated to the v5.xx firmware for Mach2 use. Sorry. Regards, George George Whitney Astro-Physics, Inc. Phone:

It was a joke

$652.99 was a lot cheaper than a new camera. Edited to add: A "new camera" would be only part of it. I'd probably need new filters, too, since my QSI uses the little 31.5 mm filters from Astrodon.

Whew, that was close! For a minute there I thought that we were going to have a CCD vs. CMOS camera debate. :-) -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery -

I wouldn't call them better.

Are CMOS cameras better than CCD? Aren't the wells a lot shallower than CCD's? cytan

Time to get that full frame CMOS.

Ouch! I'm betting that there are electrolytic filter caps going bad. Maybe I'll try replacing them all. Roland.

Rolando: My vintage 2012 QSI started exhibiting this exact problem early this year (i.e., the herringbone pattern). It briefly went away, but then it came back for good. I had to send my camera to

In southeast Texas mud dauber wasps really like to build their nests in roll off roof observatories. Wasp spay is effective but messy on equipment. As they are exploring for a nest location, an indoor
