For quite a while I've had an issue where the images I take have trails that show up when going higher then about 20 seconds exposure time. I do a rough polar alignment where you can still see the polaris in the scope as I live in the north of Sweden and the EQ3-2 mount doesn't allow for accurate adjustment above 64 degrees. I'm 100% sure that the locatation, time zone and time is correct, I've also parked the scope to the position with the scope facing polaris and the weights downwards. I did a 3 star alignment and after a 1 min exposure with my Olympus 420 the result was as the first image I attached. For 20 second exposures I get the second image attached but once in a while without having touched the scope (yes I am 100% sure of this, I stood perfectly still a good distance away from the scope and triggered the shutter with a remote control) I get results such as the third image. My guess is that the cogwheels are slipping somehow but I'm gonna ask here to be sure.
Taken in Scarborough, North Yorkshire on 16 December 2017. My main aim with this image was to show those just starting out in the world of astrophotography what can be achieved on a budget with simple and affordable equipment. Using my iPhone and the NightCap app set to Star Trails mode I captured this as one image over a period of four hours (hence the number of airplane trails!). I then edited the image on my iPhone using the Snapseed app to darken the sky and bring out some colour in the star trails. I was very pleased with the outcome given that all of this was achieved using only an iPhone and readily available, easy to use apps.
