Hi! I’m searching for my first telescope and I have came up with 2 brands in the end:

https://www.astroshop.eu/telescopes/bresser-dobson-telescope-n-200-1200-messier-hexafoc-dob/p,47842 -bresser messier 8”

Which one do you think is the best?

Clear skies!

Thanks @Ricochet!

And if anyone knows if a 2" filter can be used with the 1.25 eyepieces. I think it can screw in the adaptor?

Hi! Thanks! @Ricochet  can you tell me the acclimation time for the bresser 8" telescope with and without the fan? And maybe a link to that computer fan you use?

Firstly, the link about the thing with coma: https://www.astroshop.eu/telescopes/bresser-dobson-telescope-n-200-1200-messier-hexafoc-dob/p,47842 The excellent large Hexafoc focuser has an aperture of 64mm making it impossible to notice any shading from the focuser tube, even with large widefield eyepieces.

Of the two scopes under consideration the altitude bearings, mirror cell and focuser are reasons why I would buy the Bresser again if I was making the choice again. I purchased the 1:10 dual speed upgrade for the focuser (as well as 1.25" and 2" Baader clicklocks) and bought a 12V computer fan and battery quite cheaply to cool the primary mirror.

The 2,5 hexafoc focuser is better than the 2 crayford? Noticeable in focusing or other way?

Clear skies!

Thank you all! I have played a bit with astronomy.tools and I found out that the best combination for me is 9mm + 2x barlow. About coma I m still a little bit confused, but I ve read that the 2,5 hexafoc focuser gives no coma at 2” eyepieces, not sure I understood right. Now if anyone can help me to choose  one of the two telescopes.

Clear skies!

Hi! After gathering more knowledge about this topic I'm stuck between 2 8"dobs:

https://astromagazin.ro/telescoape/3261-telescop-bresser-dobson-8.html with a red dot finder, 25 SP and most important, after me, 2.5 hexafoc focuser single-speed (because it gives no coma);

https://www.astroshop.eu/telescoape/gso-telescop-dobson-n-200-1200-dob-deluxe-version/p,14189 with 8x50 scope, Erfle 30mm 2", SP 9mm 1,25", a 2" Crayford with 1:10 micro-reduction, a cooling fan

For any of them I want to buy an Celestron X-Cel eyepiece for planetary( I don't know what to choose between 5mm,7mm or 9mm) and a 2x Barlow or a 1:10 gear if I go with the Bresser.

I want firstly to go on planetary observing but after some time and on DSO.

Hope that someone can give me an advice.

Clear skies!

Welcome to SGL.

@Orange Smartie has touched on the questions that haven't been considered. Unless you have looked at this for yourself.

In general a 150/200 mirror dob is a good first scope. Note the 'in general'.

If you weight 50Kg, have a bad back, need to carry the scope down 3 flights of stairs, etc, a large scope is not a good choice.
If you have to negotiate storage space in a tiny cupboard, similar comments apply.
If you have to deal with a lot of light pollution, there are other scopes that will be a better choice.

The best scope is always the one that gets used the most.
I have a 300mm mirror scope on dob mount. On the face of it a much better scope.
But at 35Kg total for the tube and mount, moving and set up need thinking about.........
I also have an 80mm refractor that can sit on almost any tripod/mount.
Moving this is easy. Tube in one hand and mount/tripod in the other.

If you tell us a little about your viewing circumstances and what you hope to see, the advice offered will be much better.

Enjoy the journey,

David.

Thank you all for your time and energy! This scope isn t going to be moved too much, only in and out of my house, and storage is not a problem. I don t live in a town with much air pollution. Being my first telescope I want to see pretty everything, from planets to nebulas and other deepsky objects. I hope it helps.

Clear skies!
