    You are a gem. I was so frustrated and thought I had wasted my money but your instructions have me up and running with my new scope. Thank you so much. Celestron should upload your video as the ones on their website were useless.

    Celestron and many others are still showing out of date videos with the previous finder scope. Thanks for watching our channel. Do my best to keep it simple and honest. Shame some of our viewers don`t buy from our links . But as the saying goes "you can lead a horse to water, but can`t make it drink"

    I have this scope and I’ve coupled it with an Antares 2” mirror diagonal. I can confirm that this works fine (infinity focus is easy). I use an Explore Scientific 70deg 2” eyepiece and the starfield views are beautiful. What’s less easy is focusing a camera. You cannot achieve infinity focus with a directly attached (prime focus) camera. You will need an extension tube about 2” long. If you attach the camera to an eyepiece then this is not a problem.

    Needing an extension tube is a common thing with some, but not all refractors. It`s why extension tubes were invented. Was your diag a 45 degree prism or 90 degree. It`s usually the 45 degree ones that do not focus on infinity due to lack of inward travel.

    Great review! Thank you! 🙏Unfortunately, I bought it and it's not worth any money. To move it left to right, mine is kind of stuck, although the "screw" is all up. I don't see anything that I don't see with my own eyes, even Mars, which is a bright big spot using the telescope or not (with the telescope I see it even smaller and with colors). Also the view for terrestrial isn't very good, it is too bright. The tripod is too light, so it moves when you move the mount in the up/down/right/left directions. Also, we have to take out the tray everytime we want to close the tripod. Considering the material, I don't think it will last long, so I don't even use it. The finderscope (red dot finder) and the telescope in general seems very fragil, lots of plastic parts. Really don't know what to do with it, being a huge disappointment of 385€.

    This one should be fine for looking at the phases of Venus, cloud belts on Jupiter and rings round Saturn. But if upgrading to higher power eyepieces, but buy the best quality you can afford. But yes, the AM 90 is more suited to high magnification. We have both in stock, but the AM90 have nearly sold out. Give the 102 a chance, and check out the many rich field star regions, star clusters and brighter nebula. You will then soon find out there is much more in the night sky than the Moon and Planets.

    Would there be any benefit to replacing the prisim with a dielectric mirror diagonal? I have this telescope.

    In theory, as it is a mirror diag, there will be less chromatic aberration + light transmission will be improved. Image will be left - right opposite.

    My son and I could not get it to work. We could only see slight magnification on stars, but couldn't see close on planets (rings of Saturn were not visible at all). Any tips on what we might be doing wrong.

    The 102AZ is a wide field telescope designed for looking at such objects as rich field star clusters, and nebula from a dark sky. The astromaster 90 EQ would have been a better choice, and is what we would have advised if bought through us. The rings of Saturn should be easily visible though with your scope. So could be down to not letting the scope cool down enough, poor seeing conditions , height of the Planet in the sky, incorrect focus or using a cheap barlow.

    I have this scopes I can clearly see rings of Saturn, clouds on Jupiter and many deep sky objects both open and globular clusers, andromeda galaxy and more. Make sure you focus properly and have good weather. I also got a 6mm Svbony/68 degree eyepiece for better magnifications for planets and moon but in general if you don't see a ring of Saturn with 10mm than you probably don't doing something right. Is it shaky? do you sit on a chair comfortebly? do you touch the telescope while observing? have you focused properly?

    Spending over £200 might be a good idea to post some actual real unedited photos of things like Jupiter and Saturn's rings as this scope has a phone adapter most people have a smart phone it would give an rough idea to actually want things look like through this scope?👍

    See the thumbnail for my recent video starting with the title "advice on buying a first telescope, am I being too honest" . The reality side of the image gives a great idea of what you will see. BTW, I am a dinosaur. Have a DSLR for photos, and a basic mobile phone. No smart phone. But to be honest, as I always am, buyers need to be realist about £200 expectations and not be influenced by the fake content you see on YT by some
