So I solved my first and second problems (hue on the images and walking noise thanks to responses i got here) and now just started to take 3 minute exposures. I've used the mount a few times so far, and did the mistakes everyone warned me about, and heard the unpleasant sound of slight grinding when
I am using an IOptron Cem25p, and in the last two times, i heard a soft ticking sound when tracking. Out of 60 x 3 minute shots, 10 or so images had some star trailing consistently across the images.
Details:
- Cem25P polar aligned (no star alignment since I use EKOS and guide scope to correct alignment using its module)
- Tracking: Auto-alignment disabled. Guide scope only used when aligning initially
- Image exposure: 180 seconds
- Issue: Random images show slight star trails. Not in order, and not in steps. Just random set show this. Trails always in the same direction.
- Performed
PEC check on the mount, gave it is ok.
Thanks
