when I was looking at star shapes on my old lenses I kept the exposure length low as the test was star shape not whether there was trailing adding to the mix. Looking at how exposed your images are there is room to take short exposure length test shots. During your testing you could set the camera to jpg and raw then you get two files per image. Where my lenses where quite fast f2 or f2.8 then f4 gave better stars with less compromise on light loss if I needed to stop down though the Q200mm lens I have needed f8 really. For me it's about what final star shape can I work with in post processing influencing aperture choice.

Reads like viewing a dynamic planetarium at the telescope eyepiece that reflects a step back in time to what our great grandparents would see as their night sky if they were looking down the same eyepiece

The dark dust lanes in all the images are very interesting to see, great images

Welcome Your telescope you could start with observing objects like M44 or M45 with your 20mm eyepiece and also comet 12P/Pons Brooks. Your camera is going to be disproportionally heavy for your telescope tripod, you could try camera phone images hand held on some targets, could try the Moon. For knowing what's up where there's Stellarium and on a mobile there's sky map as examples.

Hi As an example you don't need to start with a star tracker, there a lot to learn with a camera, lens and tripod. This link was taken with a 50mm lens and no star tracker reading the post https://stargazerslounge.com/topic/420162-comet-12ppons-brooks/

Spotted the reflection too, that's awesome

Thanks for the update to this post. I've moved to using Tinkercad as well.

It would be the ST80, it can do everything with the sweet spot being wide field.

The mobile apps are easy to aim at the sky and rove around and see what's up there as it's labeled on the screen

Two apps you can point your phone at the sky and shows what looking at, Sky Map and SkyEye perhaps they might help

The camera chip in the seestar is great

Looking again my thought is cable snagging just a little can cause vibration and subsequent image wobble, and the cable to the battery when on the pillar looked to close and could interfere with the mount.

Sharpcap has a function for chromatic aberration in the latest release I've found effective when I've tried it on a few of my images.

Just as an off shot have you tried a different cable from the camera in case it's noise interference causing your banding

Deep sky stacker got a comet stacker update last year and ASTAP I think it was this year, what are you using for processing?

Thanks. The L bracket I've used here to similar effect but I'm a rubber band fan for fixings

The image is great lots to see in it. How did you mount your phone or was it propped on something?

East and West up to 50 degrees or so northern hemisphere would show little to none the lower the altitude and plus being portrait helps not exaggerate it

The orientation of the S50 is portrait and exposure length short individual frames wouldn't show field rotation that obvious though target direction influenced. A stack would through I expect from first to last frame. If you had 300 frames and stacked just one every 50 frames you might see the rotation by the way the frame edges where outlined on the stack

removed picture I'll see if can find a different one

Hi let's help you to get started. Are the trusses fully extended and clicked into their full extension. Use the 25mm eyepiece lowest magnification and slowly wind the focuser from all the way in to all the way out somewhere along that you'll find focus.

hi welcome to the az-gti, loads here https://stargazerslounge.com/topic/387014-skywatcher-az-gti-mount-owners-thread/

That's nicely captured Went outside but no visual indication of it tonight here

Active out there in a gap in the clouds capturing it, good luck if you are

Have you looked at deepskycamera beta I have lightly looked and noticed it gave manual controls but not actually using it as still trying with default app on the phone I'm not sure if I'll keep it as not getting a chance to try
