# Best lens for a beginner

Just bought a Celestron StarSense Explorer DX 130AZ for my son. What is the best lens to use for viewing planets? What are some easy tips for him, to help explorer his passion? He has the 25mm and the 10mm lens that came with it. I also bought him the Celestron 8mm-24mm lens. Any advise would be greatly appreciated..... Also, what would he need to be able to take pictures of things he is looking at? Or is this even possible with this telescope?

• One thing you can do is to check previous amateur-observing questions or search for specific keywords. There are several other different but similar questions here about trying to see the planets. People are often disappointed when they first see the limitations that the Earth's atmosphere causes. See this answer to What should I look for in a first telescope for a child? for example. For astrophotography look for a good quality adapter for a DLSR body.

• See also this answer to New to Astrophotography At 650 mm focal length planets will be pretty small on a DLSR camera's sensor so not many pixels, but a Barlow lens can help there. Hopefully additional answers will be posted by experienced astrophotographers that address your question or link to previous well-answered astrophotography questions.

• For astrophotography if there is some interest in computer processing (using free software or writing your own) then read further about lucky imaging which can give you images with better resolution than what you see through the eyepiece if you have enough data.

• Thank you Kavin, for your input. I bought a smartphone adapter for him as well, just have to figure out how to put it on. HAHA. I looked at my Canon and Nikon cameras and neither of them have the removable lens. :( I WISH they did though. So we are going to use his phone to find what he wants to look at and my phone for pictures. I will also look into getting him the Barlow lens. I'd like to help him explorer his passion without dropping a ton of  into it, just in case he loses interest. But so far, from what he's seen, I don't think he will lose interest. Dec 26, 2021 at 4:53
