Q&A: How do you attach the cell phone holder?
Answer: In the video on our page, you can see how to install the phone holder
Q&A: What should you do when your lens is blurry?
Answer: Be sure there is no sudden temperature change as that can cause lens fogging. Allow the scope to dry out and temp stabilize. Use only lens quality cleaners, microfiber cloth and typical lens brushes and air puffers. I do not recommend pressurized air like you might use to dust out a computer.
Q&
A: how old is it suitable for?
Answer: 17.7In-35.4In Adjustable, suitable for both adults and children
Q
&A: How sturdy is the tripod?
Answer: it should only take a few minutes since there are only a few joins and it's ready to go. The entire setup is a little shaky, so you have to be careful to not move the telescope too much, especially when trying to capture what you're seeing with your phone came
What is the Difference Between AZ and EQ Telescopes?
AZ = Altazimuth Mount
Altazimuth mounts are some of the most common mounts for both astronomy and photography. It is a simple manual mount that allows you to move the telescope upwards, downwards, left and right. This gives you the freedom to move the telescope freely across the sky without any constraints, alignment, or calibration necessary.
This is the type of mount most people will think of when they think of mounts in general. It is used for mounted TV cameras, professional photography, and astronomy.
People like the altazimuth mount because of the freedom and fluidity of movement that it offers.
EQ = Equatorial Mount
Equatorial mounts are similar to altazimuth mounts but they lock one of the axes of movement so that the telescope only moves along a single axis.
Which Is Better?
At the end of the day, which is better is going to be up to you depending on what you are trying to get out of your telescope experience. If you are looking for a more freeform and relaxed method of star scanning then you might prefer the ease of the altazimuth mount.
The equatorial mount does require some alignment and basic calculations to get set up properly. Suitable for professionals
