Celestron NexGuide Autoguider testing result

This picture was using Meade DSI Pro II mono, used auto stack, 5.7 seconds each, totally 998 seconds. I did not use ENVISAGE alignment to correct rotation to see what happend on guiding result.

Currently the result is positive when found a brighter star as a guiding star.

When the sky with light pollution and visual magnitude only can see Polaris...then don't switch on, it is nothing to do...guider will not function properly due to light pollution and high noise.

I also set up PEC to HEQ5 but seems HEQ5 only can tracing without problem in 1 mins by itself. Start from 80 sec can see the delay on photos. But find a brighter star and switching on NexGuide Autoguider can have a very accuracy results even 998 seconds is still pinpoint stars.


My testing comments as below:

1. Menu is simple to understand

2. Auto Cal: faster than PHD guding, it takes around 2 to 3 mins. Normally , brighter star may down to 2 mins or less for auto cal.

3. Noise setting: read the handbook very carefully on Noise setting method. You need to reduce Noise lower to prevent guider confuse and miss guding. Adjust exprosure time and Noise to find a low noise then start guiding.

Well, hope you enjoy the accuracy guiding, this is my final testing result.
