Milky Way Pano Using a Star Tracker - Sedona, AZ Part I

- I travelled to Sedona, Arizona to make a panoramic image of the milky way arch over Bell Rock and Courthouse Butte using a Star Watcher Star Adventurer 2i star tracker. In this video I go through the process of capturing the photos to create a panoramic image of the milky way. This is part 1 of 2.

During the video I reference a couple of other very helpful videos that I recommend you should check out.

Both of these are excellent videos and I highly recommend watching them.

I used the Kase Starglow filter by Alyn Wallace. It works really well and I like the effect that it creates. The filter makes the bright stars bigger and brighter while making the small dimmer stars fainter. At this time the filter must to be ordered from Kase in the UK. While you can find some Kase Starglow filters on Amazon or B&H but they are not the same filter and do not give the same effect.

This is absolutely amazing! Phenomenal job! ! I am going to sedona in a few days. Where was this taken?!
Thank you. Sedona is a very beautiful place, enjoy. I took this image from a trail along the west side of highway 179.
Thank Eric.
My pleasure. Hopefully it was helpful.
Great video Eric - waiting for Part II.
Thanks, Should have it out this weekend.
Great video... you definitely chose one of the best locations to shoot this... Love Sedona!!! One quick question here - did you have to reset the tracker mount to initial position after each shot for the sky pano to adjust the panning level?
Thank you. Sedona is one of my favorite locations and fortunately it’s only about 1 ½ hours drive way.
To answer your question, no I did not have to reset the star tracker between each shot. I roughly polar aligned the tracker and then shot the ground pano shots. After that I tilled the camera up a bit to capture more of the stars then polar aligned the tracker. Once aligned, I started the tracker then shot the star pano images as you would take a normal pano. The key is to keep the tacker running the whole time you are taking shots that way it stays aligned (or at least very closely aligned) with the stars so you can take long exposures i.e. 2-3 minutes without trails. Then when you stitch the stars together they can be aligned fairly easily using PTGUI. Hopefully this answers your question. If not please let me know and I will try to help.

Eric, I was pleased to see your answer. Once you start imaging the sky panorama, with the camera mounted on a polar aligned mount, the mount is compensating for the earth’s rotation and maintaining a fixed relationship with the sky in the sky frame of reference. You don’t want to disturb that while acquiring the sky images. During that process the earth’s horizon is irrelevant. Similarly when acquiring the landscape pano the tracking mount is off and the camera is rotated about an axis normal to the earth’s surface and that relationship in the earth frame of reference is maintained throughout the landscape pano. When shooting the sky pano, with the help of the polar aligned mount, you leave the earth behind temporarily, it’s irrelevant. It becomes relevant again in post when you combine the two panoramas (with a lot of translation, rotation, warping, and fudging).
Thanks for this video.
while the star tracker is following the star every single exposure, Do you need to position the star tracker rotator to the original position?
Or just leave the rotator following the star and you just turn the ballhead base pano to capture every exposure?
Cheers
You're welcome, and thank you for watching.
To shot the stars I started the tracker and did not stop it till I was done taking all of the images. That way relative to the camera the stars stay in the same location and you can photograph them as if you were taking a standard pano. Hope this answers your question. If you have any other questions let me know.

@@EricGebhard thanks Eric. I am not sure if this will be the same principle when we take multi row pano on star tracker? Let say 3 row and 6 image each row. In that case , the star tracker would turn quite further distance compared to one row pano.
@@akkarparkiamopas3401 I haven't tried a multi row pano on the star tracker but I don't think it will be that different. The key will be how long your exposures are. For the stars in this video I did a 6 image pano with an exposure time of 2min 40sec and a minute between shots. Additionally, I took two shots at each position for a total of 12 images. This resulted in a total of about 37 minutes. If you keep your exposure time to around 2 minutes (you will likely have to increase the iso a bit) with say 30 seconds between shots that would put at about 45 minutes, which should work. Also, I would suggest having the camera at about the 10 o'clock position so that as it rotates it does not go too far over. Hope this helps.

@@EricGebhard Thanks a lot for your info and suggestion.
