I recieved my new mount, a CEM26 from ioptron two or three days ago. I have tried a couple of times but still haven't managed to image anything correctly with the GOTO.
For the last year I have successfully imaged many targets using the GOTO system of my Celestron 130slt az alt scope. No problem at all! All i needed to do was select two stars and align each one then the scope slewed almost exactly to the target and away I went taking images. Yes there was drift and rotation but I checked every hour or two and was imaging at 30 second exposure and stacking some nice images of Galaxies, Nebulae and recently globular clusters. I felt happy!
Now after three days of struggle, youtube videos and trying to learn how this worked on an EQ mount. This is the first time I have used an EQ mount and polar aligned.
The problem is no matter what I do, including multiple slew and sync to different stars, the scope never goes exactly to the target and so if I take images there is nothing to be seen because the target is not in the frame. This is VERY frustrating!
What am I doing wrong?
Here is what I have done so far....
Balanced and levelled the mount, adjusted the latitude knob. Point my scope to north and aim at Polaris. In the accu align polar scope I place the str in the circle according to what my handcontrol and iphone app show. I noticed however that after alignment seem good that when I look through the finderscope of the OTA polaris is not aligned exactly. Should it be? I figure it maybe should??? If so, what is the process alignment using the finderscope first then use the polar scope or what?
After polar alignment appears to be OK, I do one star alignment, should i do two star alignment? I align, say, Vega and then I believe I should be good to go. Now I slew to my target and take an image. No target in frame, so I slew to another star and sync to that and check again going to another star. I went from Vega to Kochab and it was close, I synced again and then returned to Vega and it was way off. What is my GOTO doing? I never had any of this problem with my previous mount. Suggests to me that it is something particular to the EQ mount. What have I missed here?
One or two more things to explain a bit more. I notice that I am able to get good images of stars (where exactly they are I don't know but nearish the target I want lol) as long as three minutes unguided with very little star trails which suggests to me polar alignment was successful???????? Also over some time the image does not drift much and does not rotate like I had with alt az mount. It seems to work well, except for one thing....
I cannot find anything with the GOTO....my alignment is not enabling this or is the process different for ioptrn? Can't find any answers in the manual so HELP PLEASE!
Not much use going from 30 seconds to 3 or 4 minutes if I can't find my targets!!!
Grateful for any advice or help you may be able to offer to end my frustration!
