Hi guys, hoping you can help with the tracking problems I'm coming across with my astrophotography setup. I've been using it since August 2020 and have kind of put up with the problem until last night where I think it's getting worse...
Specs below (let me know if you need anything else):
William Optics Zenithstar 61 II (360mm F6.1) - Zenithstar 61Adjustable Field Flattener iOptron SkyGuider Pro Camera Mount Full Package K&F Concept Aluminium Tripod with 2kg weight Canon EOS 250d (cropped sensor 1.6x) The problem:
I take roughly 40 pics with each being 1 minute long at 1600 ISO and stack them on DeepSkyStacker. From a few people I know on the internet, it seems as though, with a very similar setup and same focal length, they can get around 3 mins of exposure with no problem. And that's without a guide camera.
With my 1 minute exposure, roughly 10 of 40 images are reasonable but the rest have star trailing or double stars (see attached downscaled, unedited pics of Orion nebula)
What I think it could be:
My first idea was the tripod, it's not the best but it's not cheap plastic, and it should be fine for a 1 min exposure. Then I thought it could be the iOptron tracker that could be faulty?
Every screw has been tightened, there's no play in any of the adapters/mounts.
I thought I'd post this here to see if anyone else has the same problem or has more experience/knowledge that could help. Also to see if there's an obvious problem before I spend hundreds on a new tripod or send the tracker back for a replacement.
Any help would be much appreciated!
I have read a couple of threads when it comes to direct driven mounts, and one of the most frequent questions asked is how to balace a direct driven mount, in my case a ASA DDM85.
- So i made one where i show the basics and how sensitive it is, but a breeze to do when using the software provided.

I know it may be a bit of a long shot but I'm looking to buy a HEQ5 Pro mount or an NEQ6 Pro or something similar. Preferably belt driven but not necessary as can happily modify it. Please let me know if you have anything! Thanks.
Hi! I'm Fran
Not so long ago I took a picture of the ISS I never thought I was going to be able to get with the equipment I have.
After saving for a long time, I was able to buy my first scope, an OTA Skywatcher 200P. I adapted it to be used in a dobsonian base because it was the cheapest way I had to get it to work.
One night, I thought it might be cool to try to aim and record with my phone an ISS pass overhead. During the first attempt, I messed up the focus extremely bad but you can't imagine how happy I was to get a white blob in a frame that only I knew was the ISS.
The following afternoon I tried again. This time the flyby was almost exactly overhead and the night was crystal clear. So I manually tracked the station looking through the finder scope and recording it with my phone at 1080p 60fps. Without much expectations I downloaded the files into my computer to review them. And was shocked with the results.
The video was processed with PIPP, AutoStakkert and RegiStax.
If someone told me the image was taken with a phone and manually tracked with a shitty dobsonian base I would not believe him! I got really lucky that night, but I can not be happier with the results. I believe I got to the edge of what I can accomplish with the equipment that I was able to buy. I'm not sure if ext step up should be a real camera or a mount. Anyway, any of them are too expensive 😬
If you want to see the frames before processing (and some nice shots of the moon that night), I'll leave a link to the video where I show them:
Thank you so much for reading it all.
