Okay so I believe eventually I want to try to do 130 second exposure forJayTee wrote: ↑Fri Aug 16, 2019 2:34 am Just a point of clarification for you for future long exposure DSO imaging, if the mount is not a goto mount or does not have an ST-4 port then you will NOT be able to autoguide that mount. You can manual guide the mount, but that is a PITA you just don't want to experience.

I will need a mount that has the ability for goto so I can auto track? Is there a mount not too much more expensive that can do that, or will I have to spend a lot more money for that capability?
So the tracking motor will allow me to track the objects manually, but I won't be able to stack the images basically because it won't be as precise as aOzman wrote: ↑Thu Aug 15, 2019 12:38 am
You will have very good views of the planets and will see MANY DSOs (remember the darker the location the more DSOs you will see). You will have to find the targets yourself and then you can easily track it manually just by turning the RA knob or can track automatically by attaching the motor. You will have to polar align the mount, which is very easy to do for visual use. It is a little more difficult to align it for imaging as it must be much more precise. You will have to learn to do a drift alignment (not hard but it is a little lengthy) and will need a reticle eyepiece for the precise alignment.
If you are going to want to eventually get into auto-guiding and lengthy exposures (and carry theBaskevo wrote: ↑Fri Aug 16, 2019 3:17 am Okay, so not the LX70. Do you guys have any suggestions for a mount that will support the 120mm?
Will I need auto guiding for 130 second exposures? I will probably want to consider that if I want to do that later on, right?
But there probably is not a mount that will allow for long exposures with auto tracking and support 50% of the weight in my price range, huh (around $400 for the mount)?
No. The hand knobs on the mount will allow you to track manually by turning the knob with your hand, this is only for visual use. Once you attach the motor, the tracking is automatic and just as precise as aBaskevo wrote: ↑Fri Aug 16, 2019 3:37 amSo the tracking motor will allow me to track the objects manually, but I won't be able to stack the images basically because it won't be as precise as aOzman wrote: ↑Thu Aug 15, 2019 12:38 am

goto tracking system. So the best can do with a mount similar to the LX70 is one, 130 second exposure of aDSO . Am I understanding that correctly?
Okay so what I indicated before, with the dual-axis motor, I'll be able to do like minute to 2-minute long exposures, and that will be good enough to get some decent shots to learn how to process and stack images? Again, I just want something that will allow me to use aOzman wrote: ↑Fri Aug 16, 2019 3:46 amNo. The hand knobs on the mount will allow you to track manually by turning the knob with your hand, this is only for visual use.

If you build your own motor drives with ONSTEP electronics and commercial stepper motors it will. Such drives will probably cost less than the Orion dual axis drive. But there are a lot of DIY components in it, so it is not something you can buy directly and use.
