Hi once again... After spending a year with the mount i built i managed to gather some info about go to systems. I am in my final year of mechanical engineering and will be displaying the mount as my project....but will b dding a go to system to it. I will b getting help from the information technology team to programme the mount. What i learnt is that you can control the telescope motion through stellarium using a raspberry pi microprocessor, a bluetooth dongle and potentiometers for motion sensing. I seen this video on youtube and will share tge link...if someone could re

Haha...at some point I too was in this position. I had to modify my telescope. I had no idea about astrographs and ended up buying an 8inch dob. No small eq mounts can take the weight of this scope. A heavy one would cost me a bomb of about 2000 to 3000$ plus shipping. So i just decided to build a mount and it does a good job at tracking . You can image with the etx90 too. Just that you will get shorter exposures. Hopefully at some point we can blow up cash on expensive equipment..??? -

Typically if u need a good shot...u would require some expensive gear. Or if u manually track and guide..u can get shorter exposures of 20 to 30 secs. That's what I do. You already have a good DSLR to do the job. As long as your mount is polar aligned well. You should get good images. I built an eq mount at home that just has a motor on the RA. But I get pretty decent images. -

Haha....yea it works perfectly. 144:1 ratio seemed to be right. It takes the load well. Just that I'm having issues with DSS. It doesn't detect many stars. Just that when I reduce the threshold below 10 the number of stars increase a bit. It just detects a dozen or so. Sometimes it just 2 to 5 stars that get detected.
