I have an iOptron Sky Guider n which I mount a DSLR, when aiming at an object and finding it needs small adjustment for correct framing I move it by hand, usually too much, this takes time , the Mount has a facilty for small movement in one direction only, Is there a Micro adjuster that I can attach to the mount and camera to make this easier, I have seen one that has two control knobs

This is a heavy cropped area of a 20 x 20 second stack of the night sky with a Conon 5D M2 and a 20mm lens non tracked . These artifacts sometime occure in colour, can anyone explain what Im doing wrong
-
Here are 3 images - single shot - grad x treminator to flatten and stretched with levels. it looks lop sided to the left and uneven stars. If I continue a light spot appears in the centre ?

The Mod was just to remove the i/r filter not full spectrum I believe. Ive had this done with other Canons twith no problems . I cleaned with a Sensor Cleaning Swab and after a air blower. I have tested the Samyang on another DSLR and it works fine so its a camera problem

Here are 3 images - single shot - 10 second single frame and 10 second stretched on levels and curves trying to detect a problem

Have tried stacking with and without flats and darks, just the same

Hi , I have the dewdrop on images taken other nights so it cant be that and used flats to no effect

Can anyone help me, I have a Canon 5dMk2 which is assto modded but cannot obtain a good image using my Samyang 14mm 2.8 lens, I have attached two images which I have processed to accentuate the problem , one stacked DSS and one Sequator , both show the same probem. I have cleaned the Sensor so dont know what that bottom right artefact is. Both images were stacked with Darks and Flats and captured at - 20 x 15 secs iso 3200 f2.8
