Astrophotography done with the iEXOS-100 and EXOS 2 post your picture and details lets show what this mount can do. #iEXOS-100 #EXOS2 #astrophotography
Good day Harry,
1. No issues so far.
2. No slippage or weird sounds from the mount when slewing or tracking
3. Tripod legs are fully extended
4. No vibration pads
5. Unleveled angled ground
6. Imaging over cement; (oh yeah, I am a rule breaker)
Things you should know:
1. Your system has to be balanced. My idea of balancing in the RA differs from
a) I can move the scope anywhere along the RA axis of rotation and the scope will not move
2. Dec balancing is a little different:
a) I can move the scope +/- along the DEC axis of rotation at 180-degrees and it will not move
to make this like the RA, I will have to experiment with stick on weights.
3. Make sure you have all counterweights installed and the RA with Dec axis locked down before
placing your scope on top.
4. You will need a bushing in order for the 11.25-pound counterweight to be balanced on the counterweight
shaft. I made my bushing out of PVC tubing.
Why Explore Scientific 11.25-pound counterweight:
1. Mr. Kent suggested it. It is countersunk, so it extends the length of the counterweight shaft
by 58.48mm (using my measurements). It is a tight fit on the countershaft screw knob, but I am
not going to turn down the knurled knob.
1. Not very good since I can’t see any Northern stars due to tree foliage. Can’t do a real polar alignment;
even Sharpcap needs stars. Currently I am doing blind polar alignment. I use apps to point me north
and “celestial pole” to get a false sense I am aimed at the NCP. Currently, I can run 5400mm with a
digital zoom of 5 and the image will cross my FOV in 1.5-minutes.
This is a picture of my current setup which I will use for all planets for 2020. I have to get Mars working.
I believe Mars comes around every 2-years. Reminds me of Tom Petty’s song, “Don’t come around here no more”.

JR, great pictures! May I ask you about the stability and any other comments you have regarding your mount. I also have the iExos 100 with the stock tripod. I see you have the ST3 tripod with the Skymax
180mm Maksutov . I am considering a similar upgrade, and am wondering how yours is working out.
