ASIAIR Polar Alignment for the Skyguider Pro and Star Adventurer.

- In this video, I walk through a polar alignment starting with setup and moving on to alignment. This all applies to both the Skyguider and Star Adventurer.
Just to clarify. Walking noise happens when you stack images of a target that hasn't moved much between frames (PA and tracking/guiding are excellent). It occurs because tracking software confuses "not-so-random" noise with actual signal...so, noise is also stacked. The best way to cancel this out is by dithering...either automatically if you have a GOTO mount or manually by slightly nudging the mount a few pixels on any direction/axis every 2 or 3 light frames.
Apart from this, great informative video
Thanks for the video and explaining how you use the device. This is something I am looking into getting in the future.
I tried with standard base that Skyguide Pro comes with.....as you said... it was "nightmare". THANKS for teh session.
Another great video George. Thanks
Hi George, another super video, thank you. I had the same worry about making sure I was turning the rig 60 degrees until I had an epiphany. The clutch on the iOptron Sky Guider Pro has ribs on it that you use to loosen or tighten it. Each one of those is at 60 degrees to the next, so I now loosen the clutch a little, position a rib at the top and rotate the rig left or right until its over the next rib. Works every time. Hope that helps .
That's sweet, I will have to check that out.
Great job. Good production man. 🤙🏼
The ASIAir mini is great if you use supported cameras which are basically some Cannon and Nikon models. I suppose you could connect a ZWO guide scope set up as the main camera to assist with polar alignment and target acquisition if you don't have a supported DSLR, but I haven't tried this myself as I use a supported DSLR. I have found the mini to be extremely good value, it does everything I need for my DSLR imaging.
I love the mini. Great piece of gear.
Hey mate, really like your video, has helped me out a lot. I'm in the southern hemisphere so aligning is a real pain. Down here with the Star Adventurer aligning is very difficult. What are your thoughts on doing a ASIAir "All-Sky" Polar Alignment Tutorial for all of us that have no clear direct sight line to Polaris or the Octans.
Let me see what I can do on that. I know someone recently (I don't know where I saw it) used it and said it was pretty good. I will do my research on this.
Happy that three videos have helped. One day I want to head to your hemisphere to image the night sky. Lots of great stuff.
I thought I'd need a guide scope and camera to polar align. This is good to know! Can the asiair help the tracker stay on target even without a gti mount?
Sorry for the slow response. Missed it.
The ASIAIR can help with staying on target, but only on the right ascension (RA) because we don't have an adjustable declination (Dec).
How did you mount the air on a tripod
There is a standard 1/4 20 hole on the ASIAIR, like the bottom of a camera.
Thanks for tis video! I have a Star Adventurer and strongly contemplating getting the AISair for polar alignment. How critical is it for the camera/lens to be at 60 degrees? Is "eyeballing it" good enough? After you are happy with your polar alignment, do you disconnect the AIS Air (assuming that is all you will be using it for)?
Roughly 60 degrees is fine. Unless I am using it to guide, I do disconnect it.
@@astroventure2221 If you are in Utah, shouldn't your latitude and longitude be some values far different than what your ASI Air is showing?
@davidletz9123 you are 100% correct. It's changed for my safety and these coordinates take you to a place on the earth that I thought would be cool to go to.
@@astroventure2221Smart move on your part!!
Given the iPolar is $218 (and especially because is needs a PC, no mobile app) and the ASAIR Plus is only a bit more, this seems like a no brainer???!!
Let me muddy the waters for you and trek you why I have both. To tweak the polar alignment with the ASIAIR, you have to come off target. And the longer the night goes, the greater you will drift from the target causing the stars to elongate. With the iPolar, you turn on the computer to reconnect and make your adjustment while never coming off target.
Why no guide scope ?
Because this video was about PA.
@@astroventure2221 so you typically use a guide scope? I was looking through your videos to see if you used one with asiair and a star Adventurer as I'm trying to figure out setup and usage.
@@PantherSpawn I can put a video together for it... when I get some clear skies.
@@astroventure2221 Can you also polar align through the guide scope?
@@davidletz9123 You could, but wouldn't want to. The PA off the guide scope is going to be slightly different from the camera's PA.
