I'm new here. Im buying my first telescope from olx. Maker is Durabrand. I never heard of. Also there are no parameters mentioned on Tube about focal length or aparture.



I am buying this due to cheap cost. Is it worth to buy?



Thank you.

That sounds like a department store's house brand. Unless it is so cheap that you do not mind throwing it in the garbage if it is no good, it is probably not worth it.

How about this one?



Sky-Watcher BK 1149 EQ1 114/900

Focal length: 900 mm Luminous range
: 7.9

1.25 "glasses. - Super 25, Super 10
Barlow lens 1.25"

T2 connector



Can I see nebulas , galaxies and plantes clearly?



OR



Sky-Watcher Dobson 6 "telescope is better?

Sky-Watcher Dobson 6 "telescope is better?

Welcome to TSS! Sky-Watcher Dobsonian 6" is much better scope than Sky-Watcher BK 1149 EQ1 114/900. 6" Dobsonian will provide nice views of nebulas, star clusters, galaxies, planets and the Moon.

Definitely go for the 6" dob. You won't regret it. The other on the EQ1 will be frustrating to use as well as considerably less aperture.

Third on the 6". Reputable maker and as David said, much more solid than the other offering.

Go for it and all the best,

4th!

If I had to choose between the telescope in the link and a 6" dobsonian I would also go with the dob. I'll be the 5th. I remember my 6" dob with a lot of fondness. I have a telescope similar to the one in the link gathering dust in the back of my garage.

I see you also posted about this over at Stargazer's Lounge and received similar advice. I realize that you are limited by the cost consideration, but if you will put a little more money into the pot and go for the 6" as others have recommended, you will be infinitely more satisfied with the results.

If you have to ask if you can see galaxies and nebulae with a 6" then you probably never looked through a decent telescope. The answer can be yes or no depending on your expectations. I have a 12" and I think it's so so even in a Bortle 1 sky. I looked through a 22" Obsession and it's a lot better in Bortle 1 but I still can't see color. A 28" did the trick for me, I saw M51 in color - I think. So if you can go to a star party and look through a telescope then you can decide how much you should spend. My 12" is good for M42, M8, M17, M31 and M45. You will not see the pretty color pictures on the box. I have a supermarket Venture RX7 for $90 and enjoyed it. Not because of the great quality but because it came with all kinds of gadgets that taught me what you can do and what matters, it made me see some things and it was easy to set up and to play with. And I did not have to sit down low like with a 6" Dob with a special seat or a piece of furniture to raise it. The enjoyment of this hobby is not just in what you can see but also in connecting with others and sharing your experience. If you can make the best out of what you've got there are a lot of options. I get my fix once a year looking through other people's big Dobs while also bringing my own little 12".

It is not the size of the scope, it is how you use it. Heck, I can see galaxies, nebulae and star clusters naked eye if sky is decent. I believe what the question really means is whether 6" DOB is a good hobby scope, and I think most would agree that it is.

I can tell you first hand that size matters big time. It is the number 1 on the list.

For instance I had a decent view of M19 in my Z12, then I went to Gene's 22" Obsession and saw all kinds of clear cracks in the nebulosity that simply weren't visible in my 12". The globs in his scope filled mkn the whole FOV, in my Z12 they were just a small circular blob. Unfortunately there was no 28" available so the color was still missing but the views through a 28" are another step up from the 22". The Obsession page has a clear comparison of what you can see with different scope sizes, and it's exactly like that.

You must be referring to reflectors of sizes 6" or less. It is well known that you can subtract 2" from a reflector aperture for an equivalent frac quality, true. But above 10" it's a different ballpark. And viewing through to those can be enjoyable too but there's simply no comparison with big Dobs.

Sure, aperture is the queen and larger scope will reach deeper and show more details. The same applies to photography, zoom lens will show you more details, but people still buy wide angle lenses. Sometimes you want to see the tree but sometimes you want to see the forest.

Also, not everyone enjoys weightlifting. Try going camping with 28" DOB or take it up flight of stairs. Every place I lived or observed required carrying, lifting, climbing. Your learn you weight limit in scopes pretty fast.

We seem to have side-tracked a bit here, so back to gauraog's request about the 114mm Skywatcher vs the 6": I agree fully that the 6" dob is a better scope for a beginner (in particular that EQ1 mount has resulted in more scopes being left in the cupboard and never used again due to frustration than any other factor!), however if the 114 is all you can get it still gives good views (once you work out how to move and point the mount!). All the Messier objects are visible, and hundreds if not thousands of dso's, double stars, all the planets; and the moon is fantastic.

As I have noted elsewhere, the classic 114mm reflector can show just as much as a modern 4" Apo refractor (if not quite as sharp sometimes).
Personally, I love the views of dso's through big reflectors (the biggest I have viewed through is a 30"), but I usually go back to my 4" refractor quite happily.

All scopes have their limits, and I think a lot of joy comes through accepting it and pushing the scope and your eyes to that limit. I have had some pretty amazing views through an old Tasco 114 on that dodgy old EQ1 mount... I'll always remember my first view of the "Leo trio" under a dark sky where I could even make out the gravity-distorted edges of NGC 3628, not to mention the Shoemaker-Levy cometary impacts on Jupiter!

Certainly if you can afford it go for the 6" dob: the mount is much more intuitive and the views brighter: but be prepared to either spend time on your knees or get an observing stool: the eyepiece can get pretty low with a small dob!

All the best, and happy viewing,

Dean

(BTW: a question to Henk: what "color" have you seen in M51 etc. through a big dob? Was it the red of star-forming regions? )

No it was blueish green with some yellow.
