What advanced Telescope should you buy after A Beginner One?

My first ever telescope was a DIY refractor that was made of a Zeiss lens Kit. This was a thing back in the times of the former GDR. It basically had no focuser and was nowhere near the things I use today. But as a kid, this was amazing.

The first ever telescope I bought myself was some kind of a mixed Newton and Refractor thing I bought of ebay many years ago. It was a mess!!! The optics were so bad, that your eyes hurt the moment you looked through it. The mount was very flimsy, but it was the best part of the whole thing. It was unusable at 1400mm focal length. Thats the price I paid

Then I bought a Bresser Newton with an EXOS mount. I only needed the mount so the telescope was an add on if you like. I took my only ever moon image with this scope and a Canon M50. The result was great, but I never used it again at f/10. The mount was used to get my first images with a Canon 300mm lens and my EOS 5DII. It had only a simple motor drive and was not controllable by a PC: But it worked to get some basics.

So it took me 3 tries to accept, that I have to investigate what I need and like. I made the best decition ever and bought my EQ6-R Pro with a TS 8" Newton. This was the first rig I was successful with. The mount is part of one of my 3 permanent setups. The newton is used less nowadays, but I still get him out from time to time.

Tho suggest what to buy next depends highly on the things you are interested in, your budget, your location (light pollution), etc. This is not easy to answer. For deep sky targets I would recommend a refractor. It is easier to use and you get them with all possible focal lengths. But the first thing to invest in if you decide to go further, is a sturdy mount. It is by far the most important thing and you should buy the sturdiest one your money can buy. This is key to everything. More important than a good new telescope.

+1 on the mount

As Christian said, the rest is up to what you are interested in doing. Visual observing of deep sky objects, photography, lunar/planetary, double stars, pro/am research? Don't expect to be able to answer that right away, it takes time and experience. You might find that joining a local astronomy club helpful. You'll be able to discuss this with a lot of people and see a lot of different scopes in action at star parties. It's a great first step for getting deeper into the hobby.

Thank you so much. Good advice. I currently have the Skywatcher AZ Pronto with a 114mm aperture and 500mm focal length. What objects in the night sky can I see with this? Would really appreciate the help because I'm new to the hobby. Thanks.

I think it depends on what you want to do, how dedicated you are, how mobile you are and how much it hurts you to spend money.
A few months ago, when I started with this hobby (actually restarted, since it is my second attempt) I went all in and got an AM5 Mount with an Askar V Telescope and a cooled camera.
Why did I choose this setup?
First, I need to be mobile. Since I dont have a backyard and no car everything has to fit on my bike and a backback somehow. Easy portability and the stability also keeps me motivated to go out and take photos.  My first attempt with a DSLR, a star tracker and a flimsy tripod really killed the fun for me. This is one criterion: How mobile are you?

Second, I loved the possibility to have 3 to 6 focal lengths in one, depending on which ones one considers useful. This way I can try different targets and see what I like most and when I travel, I can just pack the parts I need to do what I want. Second criterion: What do you want to shoot and are you willing do deal with lots of equipment and configurations?

About the price: 2000 EUR for a telescope sounds a lot for a beginner, but if you are sure that you want to proceed with this hobby and can afford it without selling your house, it is actually a bargain, considering the flexibility. Of course this was the least expensive part of the setup… Third criterion: Money

And the last criterion that I realized and probably the most important one: Where do you live?
Here the weather is mostly bad, clear nights are rare. That means, I dont have time to spend hours to set up my stuff, wait for cooling and to shoot with a slow f-ratio, esspecially I want to to get some sleep before working the next day. Otherwise I need a full year to shoot a galaxy. My 600mm configuration with f/7,5 is nice for now, but I am really think about getting an additional f/4 Newton with 600mm which should still be portable and saves me some time.  I also was thinking about an EdgeHD because of the focal length and the resolution, but now came to the conclusion that this would just not be useful for me.

I hope this gives you a few ideas, which things you should consider.

Thanks. Appreciate this. Keeping touch guys!

The first telescope I owned was a Celestron Newtonian. I actually won it at work and had no idea what I was doing. One night I set it up and viewed Jupiter and was blown away. Granted, Jupiter was a small spinning dot, it was the coolest thing to me. From there, I was hooked and went down the astrophotography path. I read a lot of what not to do or buy when you’re starting out. I ended up with the Redcat 51 & a ASI533MC pro dedicated astro cam. It such a great little quality scope for widefield astrophotography and I would highly recommend. I am actually looking for my next scope and was thinking of the Pleiades 111 which has a longer focal length than the Redcat 51 (250mm vs 528mm). My goal is further target detail, but still doing widefield at this point. It’s such a fun hobby and something I thought I’d never get into. The amount of knowledge I have gained is crazy! Good luck with your scope hunt and clear skies!
