2-star alignment

I sold my AM5 today. I grew tired of waiting for a true multi-star alignment. Plus, I prefer a real hand controller.

Great! I'll check it out and report back if there are any issues. Thanks for the update!

Are you saying the aforementioned test firmware was not adequate?

ASIMount@ZWO

Before I test it out, can you please confirm how to actually perform a multi-star alignment?

Do I just GoTo a target, center it in the eyepiece, and SYNC in the app, then repeat?

In alt-az point mount north, go to home. Goto desired target and center in eyepiece as you stated. Tap the target again then sync then repeat. Problem is it does not work. ZWO has stated on here that the pointing model is incorrect so makes one wonder why they pointed you to the beta to try. It can get within 3-4 degrees, sometimes a little better, but then as you progress going to targets it falls on its face. Hopefully they will fix this for visual folks.

Thank you! This is very exciting. Could you point me to the instructions/manual for doing this?

I would like to be able to do EAA and Visual during the same session. Wondering whether this will be possible without having to change the mount mode back and forth between Alt-Az and EQ.

Hi arunka and rN4MfW,
We updated this feature in the firmware V1.2.4.
You can now do multi-star alignment (maximum 100)via repeating one-star align.

Thank you again!

So, can a do a polar align, multiple one-star-aligns and then use the mount to go-to any object in the night sky while in EQ mode?

Is what you mentioned only applicable for Alt-Az mode?

ASIMount@ZWO

arunka
AM5 can do both.

ASIMount@ZWO AM5 can do both.

Thank you for your reply, but it is unclear to me. Do you have to do separate alignments for AZ and for EQ ?
Say, you did multiple-star alignment in AZ mode, then you switch in the AM5 mount app to EQ mode, and you have to do the multiple-star alignment again ?

Is the version "AM5 v1.2.4 beta" still in the beta stage which you announced on 17 February 2023 ? Some posters on this forum write about the bugs in the beta version which gives them incorrect alignment.

Hello, just wanted to provide an update. I can confirm that multi-star alignment is working in Alt/Az mode. It's not perfect but it gets the object within my field of view consistently. Using an edgehd 8" with 7x reducer and ES 24/68* eyepiece (1.15* aFOV).

Hi. I bought AM5 for use in alt-az mode. Is there a good set of directions available for using the mount in alt-az mode? The AM5 user manual does a very poor job. For example, nowhere does it say that you have to rotate the entire mount and tripod 90 degrees when switching between equatorial and alt-az modes. Correct me if wrong, but for alt-az mode, if you put AM5 in home position, the mounted telescope should point due north at the horizon. Right? (I am in northern hemisphere)
Polar alignment with the ASIair as far as I can see is for EQ mode only and useless for a polar alignment for alt-az mode, since in EQ mode the mount is rotated 90 degrees from where it should be for alt-az.
How is a polar alignment done for alt-az mode?
I would like to use the mount in alt-az mode to track the sun during the upcoming eclipse. What alignment steps do I need to take before performing goto to the sun (and switching to solar tracking rate)? Do I need to do polar alignment the night before so I can use Polaris to perform polar alignment?
Or to do a good tracking job for the eclipse do I need to use the mount in equatorial mode?

ASIMount@ZWO

spot37a Hi,if you track the sun during the upcoming eclipse,you should use the mount in EQ mode.
Polar alignment with the ASIair only can be used in EQ mode.

Hello - I tried tracking the sun with AM5 in alt-az mode and it worked fairly well. With mount in home position, I pointed scope as close to north as I could and leveled the mount.
I then used the ASI mount app to goto the sun, and set the tracking rate to solar. I used hand control to center the sun. It tracked and stayed close to center over a 2 hour period.

I have also been working on using ASIair to do visual observing gotos on AM5 in alt-az mode by using a guidescope to do plate-solving gotos. It works very well. If you are interested in that, check my posts on Cloudy Nights:

ASIMount@ZWO I need your help -- I do have the Am5 with a 30mm ZWO 220 guide scope with ASI Arir plus and I have it on celestron c8

I just want to use it as a go-to mount, but I'm having trouble figuring out what I need to do to use the goto function. I know it may be a simple question, but I need your help. Do I do a two-star alignment? If so, how ? I am at 34 degree latitude. I tried to use the guide camera as my main camera and then do a polar alignment, but it fails on that.

Please help me
thank ypu

Zaki Under normal circumstances, through the official ASIAIR App, you can follow the boot Settings. If you run into problems, you can submit bugs and logs directly in the app.

ASIMount-ZWO Can you please link to any documentation or videos showing an AM3/N or AM5/N in visual Alt/Az mode, doing a 2 or 3 star alignment, and then using just the app to provide go-to functionality. No ASIAIR or camera needed. I am interested in buying one of these, but want to see that it will indeed work as an Alt-Az go-to mount without any additional hardware.

Thanks!

ASIMount-ZWO

fYMlUkV6 You can get instructions for Alt/Az mode on official website.

ASIMount-ZWO Thank you, but unfortunately the phrase "Star Alignment" doesn't even show up once in your AM5N manual. Many ZWO mount users that I have recently asked about this feature say it either doesn't exist or only does a single star alignment only and works poorly.

I purchased a Sky-Watcher Wave 100i mount instead of the ZWO due to the fact that I know that mount supports visual Alt/Az multi-star alignment go-to, just like every previous go-to mount Sky-Watcher has made.

If your mounts truly support this feature, I would advise you to update your user manuals, website, and/or make a video showing this feature actually working.

When I began shopping for telescope mounts, cameras, and accessories I was ready to do a full ZWO ecosystem build, unfortunately due to the poor experience I have had with getting basic questions answered on your products, I'm not sure if I will use any ZWO products at this point.

Isnt the whole point of the sync function within the stargazing (now sky atlas) app is so you don't need to do multi star alignment? Simply goto target, adjust with the hand controller to centre target and sync. Job done. No multi star alignment needed.

fYMlUkV6

Astrop You can't use "go-to" functionality until you do some type of alignment first. If you start level and pointed North, the first go-to you do (and then adjust and sync) would be a 1 star alignment. This is low accuracy and will work OK for other objects close to that star. I have asked numerous ZWO mount users on Cloudy Nights and have gotten a lot of great feedback over there. It does seem like you can use the mounts in Alt/Az (no ASIAIR or camera) and get some level of successful go-to functionality with Sky Atlas (maybe multi-star, maybe just single), but ZWO does a very poor job in communicating what is possible, and I think it's likely because they want to sell you all those other products anyway lol

I bought a Sky-Watcher Wave mount instead. Their customer service is much better in the US from my experience.
