I made an absolute positioning system for the Sky-Watcher Star Adventurer tracking mount. Kind of like a GOTO system where you can point the camera on the mount at any point in the night sky with ease! It works wonderfully and is a game changer for shooting small objects like galaxies with long focal lengths!

Really hope Sky-Watcher take notice of this one. The scale with indicator on the declination bracket seems like a bit of a no brainer to me for something they could add. Nicely done.

Hey Kamil, Thank tou so much for this video. I was researching and trying to understand why this system work exactly and now everything is so clear in my mind. Basically when we polar align our tracker. Our RA axis is also aligned with the Celestial Equator. The Celestial Equator works as a clock with 24 hours, starting the 0 hour in the East. Each hour contains 15°. This is the reason the Hours in the Hour Ring in the star adventurer starts to be counted to the left. If you point your telescope to East and align the 0h to the 0 in de Date Ring. When you start to ascend your RA Axis, the 0 in the date ring will show exactly in which hour you are. There is no need to have a time lapse or so, the Hour Ring is there to show you that information. I don't know if I'm clear. But I loved to learn it and see how precise it is.

Hi Kamil. I made it!!!!! It works! If I new how to record a video ...I am not KZfaq man but maybe you can do it 1. Declination scale in Southern Hemisphere is -0....-90....-0 ( in Northern Hemisphere is 90...0....90) like You made.For SH: If object has coordinates+ , than use scale ( 0-90-0) but turn camera lens to backward. For NH: if object has coordinates -, than use scale (90-0-90) and turn lens backward. That's about Declination. I made a protractor both scales on it. The next is a RA. There are 3 ways to do it ( beside yours and Bob). It took time for me but result is very impressive. RA: print protractor 20x150 mm 0-6-12 hrs for SH and 12-6-0 for NH. Attach it on RA barrel ( in front of batteries compartment) . Level RA vertical using waterpass and mark indicator on the RA disk opposite 6 hrs. 2 nd method: Cut a disk internal diameter = diameter of polar scope protractor. External diameter +1 cm to the previous hole. Print a scale on this "wash" SH 0-6-12. NH 12-6-0 ( There is a website I found. Can share later). Like before: level RA axe vertically using waterpass and glue white thin strip or use white nail polish to make an indicating line on polar scope eyepiece tube. In this case your PA setup for SA will not be affected. And last like I did : print a scale 5x 91 mm 0-6-12 ( 12-6-0) attach on top of original hours protractor. Release meridian groove screw and align 6 with groove rotating RA with waterpass control like before. I would like to share my protractors with community but don't know how. Glory to Ukraine. Cheers. Alex

Nice video. Could you get around needing the time lapse video if you read the hour angle based on a rotating reference point on the rotating date dial? My understanding is the time is set by matching it to the date. What it looks like your reading in the video is the date based on a fixed time reference point. I am waiting on a star adventurer and not sure my understanding of the dials is correct though. Either way the time lapse solution is a creative solution and keeps your reference point when you can easily see it.

Great Video. I was wondering if this can be applied to the SkyGuider Pro? I have had minimal success finding objects with that mount. I use APT with platesolving but it is blind pointing to find an object and takes a while. The protractor method is a nice touch but the Skyguider Pro does not have a RA scale. Is that a protractor too?

@ascaniosobrero 3 жыл бұрын

I think, however, that someone with good will and the necessary programming expertise could make proper use of all the informations any smartphone can actually provide. GPS, compass and inclinometer could make the smartphone anchored over the camera lens the ultimate pointing device. Something like the Celestron StarSense Explorer app (which as such requires a code to be activated)

hey, maybe i missed this, but could you share your 24hrs video with recorded ring rotation? I think it can be applicable for anyone and no need to record this video on our own.

Hi Kamil. Great video (and great channel, BTW, I'm learning a lot from it :)). I have a questión WRT the HA adjustment. I've seen in your video (and in other ones as well) that you use the rotor marks to adjust HA, but why not use the marks in the stator instead? they are supposed to be graduated in hours (24 for the whole stator although there is engraved only from 6 to 18). I've been using then with good results so far

Hi, Kamil. I know this video has been out for a while. Thank you for putting so much hard work into this and everything else you do. Having a SkyGuider Pro without any direct application of your method without modification got me thinking (I'm an engineer and can't help it)... I'm trying to find fault with my logic of using my iPhone's built-in compass for Az and its level feature for Alt. I know the compass is a little off from celestial north, but couldn't one find out the difference from one's location, hold the compass to one's lens/mount and dial in the Az, then switch to the compass and set the Alt? I remember reading in a comment that you're a programmer. I wonder how difficult it would be to write an app that uses both features as well as gps to find tru Az and then Alt...? I'd buy that app in a heartbeat. Thanks again.

I hope someone can maybe answer a few questions on this video. First, where is the zero hour for the RA. It appears to me from the video that it is where the bracket is rotated parallel to the ground and on the east side of the tracker. It would seem without knowing where that is, it would be impossible to rotate the bar correctly. Secondly, given you know where the RA zero hour is, why can't you just rotate the bar X number of hours as appropriate. Thanks

At around 6:25 you say, "This is the Zero Hour Position." How are you locating / defining that position? Is that position defined by aligning Oct 31 on the Date Graduation Dial to the zero on the Time Graduation Dial, or is the "Zero Hour Position" defined by positioning the declination bracket in the horizontal position? Because when I align Oct 31 with zero on the Time Graduation Dial my camera is not in the same position as yours in the video (horizontal). I did calibrate my SA to ensure that when I align Oct 31 to the zero of the Time Graduation Circle my crosshairs are correct, with 0 and 6 perfectly vertical. But in this position, my camera and declination bracket are NOT vertical. I am wondering if each SA is different with this regard, and if so, I need to make my own video or lookup chart as you have done. ???

I don't have video editing software, so I just drew a circle with labels corresponding to the markings of the fixed 24-hour time graduation dial on the SA. If I have it correct, the hour angles of 0 and 12 correspond to 18 on the time graduation circle, hour angle 6 and 18 correspond to 0, and hour angle 12 and 24 correspond to 6, and so on. With the SA set to hour angle 0 / 12, if the zero on the time graduation circle is aligned to 10 on my date graduation circle, then to point at an object with an hour angle of 5, I would rotate the RA until the 10 on my date graduation circle aligned to 5 on my time graduation circle. Yes? It is easy enough to draw a circle (a clock) with these markings for reference. Or make a chart. HA 0 = Dial 18, HA 1 = Dial 19, etc. The picture is more intuitive than the chart, IMO. Let me know if I have made any mistakes here. I hope to test this soon.

I can easily see it but I also took a picture and drew center lines in the image to confirm.

I would believe that with the addition of the degree scale on the declination bracket, we should be able to point the SA at our targets using the coordinates of the target alone. It just requires some initial calibration and measurements. For example, knowing the exact position of Hour 0 with reference to the date graduation dial, which seems to vary from one device to the next. Of course, this assumes that the Time Graduation dial is accurate. On my SA, Hour 18 is NOT at 90 degrees from zero! It seems they just did not design this thing for that level of accuracy. I am curious if others can confirm this on their SA. On the time graduation dial, the 6 and the 18 should be at 90 degrees from the zero mark. Mine is not. Are they all like this?

Thank you indeed for this video. It would be fantastic if you upload the timelapse video you did with the hours / HA which no doubt will help us even more in finding the objects we need. It is possible to see part of the timelapse video you did but what could be better than having the full one? Ireally liked this helpful and interesting video, and again, my thanks. Regards from Chile 😀🇨🇱

After closer inspection, I am finding that the zero on the time graduation dial is not 90 degrees from the 6 or the 18 on the time graduation dial. You can see this if you turn the SA on its side. The 6 and the 18 are visually off center from the centerline of the scope. I can easily see it but I also took a picture and drew center lines in the image to confirm. And I can confirm that turning by 90 degrees from zero on the time graduation dial does not land me on 6 or 18. Is my SA defective? Has anyone else noticed this?

@petertrahan9785 2 жыл бұрын

Maybe this is because a sidereal day is not quite 24 hours. But only by 4 minutes. When I rotate my SA from the 18 hour position to the 6 position, it noticeably rotates more than 180 degrees. This is easiest to see by using the reticle. On my SA, this rotation results in an over rotation of 30 minutes.

at 9:15 you lost me. I just got my tracker over the weekend and have been watching your videos with interest. I sent the scale to the printer, have to go check and see how close it came out. My paper is 8.5x11 inches, I'll have to fudge numbers just a bit or trim off each end and print just a bit longer. But, for now, I'm lost with the two dials on the back...perhaps you can give me a simple explanation?

Very cool, thanks for doing this. Another thing that would be useful would be written step by step instructions. Especially when it comes to Meridian flip.

I will do that in the followup video. I will also demonstrate all 4 cases: with/without meridian flip and negative/positive declination angle

@@kamilkp The truth is that this method that you have given us is amazing. I also spend a lot of time finding the objects. I started using Astrometry.net and it is great but you need Internet, the problem is that to obtain excellent results you have to go outside the city and sometimes in mountains which makes it difficult to get at least a decent Internet signal. With your method, goodbye to that problem and much more efficient and faster than other solutions. You are great Kamil!

Kamil. Love your vids. But. I am no dummy. Ive watched this video prob 20 times. I understand it perfectly. BUT. when I use your system it’s at least 2.5 numbers off on that back scale and it’s not pointed at Vega. 39 degrees on the scale is perfect for dec. But if stellarium says 22hrs. I subtract 12. That leaves 10 hours. I look at your vid and go to 10 hours. I then duplicate that to my setup and my camera is not pointed to Vega. Not even close. Sorry to keep bugging you. I’ve been at this non stop for two days except I slept a little. Is anyone out there tried this yet and had success? Frustrating

Not sure what you mean. The Hour Angle of Vega or any other object depends not only on your location but also time of day/year etc. It changes all the time

Like I said it changes all the time as the earth rotates. You need to look up the value of Ha on location at the moment when you wanna point your camera at an object

@@kamilkp that’s what I am doing. I open stellarium. I go to hours. It’s running. I scroll in your video to that and it’s way off from yours. Yours might point at 3 and mines at 11 for an example.

Nah the star adventure weighs 50% less, costs 40% less, and doesnt require an external power source. It blows the eq35m usage out of the water in every regard but weighy capacity

Hi Kamil! Well, I tested your system and… it works !!! I was able to find M81 and M82, M51, M101 and Vega very quickly. Some in the first attempt and others until the second but it is wonderful! It saved me a lot of time and I didn't have to use my green laser to guide me. Of course, I helped myself with Astronometry.net to confirm. I did several tests at different times and at most it took 2 attempts. Without a doubt I should have made a mistake but this system that you have shared with us is a huge help. You will certainly perfect it, I don't think I can, you are the smart guy 😁. I will wait impatiently for the video where you will explain in more detail this amazing method to find objects for those who at the moment do not have an automatic goto system. IT WORKS Kamil !!! Thanks a lot !!! Greetings from Monterrey Mexico.
