Really pretty image Tom! I'm just learning PI myself and have the same challenges with the image going soft during the noise reduction. Steve's comments are where I'd go too - a tad soft, maybe back o

Steve, thanks for the video link. I watched a video this morning that introduced me to a masking approach in PI that is very flexible and easy: https://www.youtube.com/watch?v=1Fj1o8sdyv8 Anyway, this

LOVE IT Bob! Nice shot!!! Stuart

Terry, no evidence of problems here - wow! Lovely shot! Stuart

Terry, it looks excellent to me - nicely done! Stuart

Best guess is that your guider cable is not the right one. The connector at one end being reversed from what is needed will cause this effect. The direction of rapid movement will be a helpful clue. I

Steve, the reflection could be from inside your filter wheel or adapters for connecting it. Or from an OAG. I recall years ago that some people complained of flaring and odd artifacts that were traced

Kent, I too think it is his filters but the positioning of the flaring from the very edge of the field suggests to me it is the edge of the filters not the coatings (else this would be on all bright s

So, Steve and Joel, does it makes sense that they're caused by scatter off of something in the light path between the flattener and the chip and the flattener is directing the scattered light back dow

Steve, did you already say if it was affecting all filters? Stuart

Steve, thanks for clarifying. Sorry I got confused. I think Rolando's comment about it being very close to the focal plane is a great point. Also, it looks like it moves around the edge of the frame.

Ron, you'll probably get this response from lots of folks. The power connector has a split pin in it that sometimes needs to be gently spread with a screwdriver to ensure solid connection. If the moun

Carmine, do you have the hand controller attached? Did you use it during this process? Another thing that happened to me with TSX and my AP900 CP2 was the timezone offset got reversed. It went from -5

Can you say more about that last point Carmine? Stuart

Hmmm. So does TSX think your latitude is S or N? I had a number of parameters get toggled by who knows what. It happened when I reconnected my camera after sending it for service. All sorts of pop-ups

Marj, I too would love to see an external solution that allows the AP900GTO and AP1200GTO owners to benefit from the entirety of the CP4 and APCC. Stuart

As I said in my earlier reply, when I reconnected my camera I got a whole host of settings changed without touching anything in TSX. So, did you see any pop-ups that you just said "Okay" to but were r

I'm stumped. I would go through every setting related to your location and the time that TSX thinks you're on. Timezone, DST, longitude, N/S, etc. Stuart

That could be (the battery) but we've been warned repeatedly that we can't mix TSX and the hand controller. If your last slew with the hand controller was to something other than what TSX had last sle

Vince, if it does turn out to be the grease, check out Scott Hammonds' video on regreasing his AP1200 mount: https://www.youtube.com/watch?v=R7s2kTzFNF4 Stuart
