Hello,

I know you've seen these questions a lot (unless your new) but I'm struggling a lot on if I should buy a Skywatcher 250px (10") or 200px (8") (dobsonians). I have a 5 inch and i'm looking for a big step up for noticeable changes. 

Thank you

Both will give you a noticeable step up in performance on deep sky objects, less so on the planets.

The 250 is F/4.7 wheras the 200 is F/5.9 so the latter is a bit easier on lower cost eyepieces than the former and a little less fussy over collimation.

If the deep sky is a big priority for you then I would definitely go for the 250PX.

I've owned them both and liked them both though :smiley:

Hello. All things being equal then bigger is better. It has more light gathering ability. Which is always better on the fainter DSO. But bigger also can be more problematic in lifting , travelling, setting up in general. I have a 14" and a 8" and finding lately I am using the smaller scope more due to the practicality of the scope. The best scope is the one you will use. So if you have no problems with handling the 10" then go with that, otherwise the 8" is a great all round aperture for most.

Hope this helps

I was going to purchase an 8" Orion dob, and Wolfi at TS helpfully pointed out the SW250px for about the same money.

I'm so glad that I went for the extra aperture - I wanted a versatile all rounder, with good capability for DSOs.  It showed me loads!!

Ah you'd only be wondering what that extra inch would do for you ;)

I’ve a 250px, it’s pretty portable and I’m very happy with it.  It works for imaging too depending on mount. I had a 300 but it never got used as was just a bit on the big side for carrying in and out of the front door.

I wish there was a 9" dobsonian.

I can't recall any 9" Dobs, but Starmaster used to make an 11" Dob.

How heavy is it to carry?

No problems.  I’ve also had a 8” and it is a one handed job.

On the deep sky the difference between 8 and 10 inches is very significant. This was the first jump I made as a beginner. Visually it's worth it. As for handling them both, that's very much up to the person and the circumstances but I'd go for the 10 myself.

How much is light pollution going to affect my view with the 10"? (bortle 6.8)

I have the 250PX on order. Recognise that this one is less forgiving of lower cost eyepieces. Could anyone offer advice on a good step up eyepieces ? I have the Explore Scientific 6.7mm wide field (82Deg) eyepiece on order - any thoughts on this combination?

      Hi I am fairly new with telescopes and I noticed my telescope needed collimation. I preview the collimation at the beginning (tell me please if its alright) however after I finished the secondary mirror kept tilting and not staying in place as seen in the video. This is a Heritage 130P telescope. Please help.

      Hi,
      I am hoping someone here may be able to offer some help or advice. I have submitted a support ticket with Celestron but I am still waiting for a reply and would really like to get this working ready for the next clear sky!
      I recently brought a starsense but have not been able to use it because it comes up with the following errors,
      Err: Model Num
      The telescope model could not be read and initialization cannot proceed.
      Critical error!
      File: ..\source\mo
      Line: 1468
      An unexpected error occurred that may cause the HC to not opperate normally.
      When updating the controller and camera it finishes succesfully but when I check for new updates it proceeds to install the same one again and again.
      I can still control the mount and I think the camera tried to do an alignment in my room.
      I have a Celestron Nexstar 6SE.
      Thanks

      Hi everyone,
      I'm completely new to telescopes and know nothing but I want to learn and I need some advice!
      I have a budget of £200 which I can't stretch. I really like both the Skywatcher Heritage 150p and SW Skyliner 150p which I believe has been along longer than the Heritage.
      I would like to take the scope out occasionally to dark skies (so the heritage would be easier to transport) but with 2 very young children at home the reality is that I will mostly be using the scope in the back garden.
      Obviously both scopes are 150p but come with different accessory spec (specs below).... please could someone advise which would give me the most bang for my buck?!
       
      Heritage 150p:
      Magnifications (with eyepieces supplied): x30 & x75
      Highest Practical Power (Potential): x300
      Diameter of Primary Mirror: 150mm
      Telescope Focal Length: 750mm (f/5)
      Eyepieces Supplied (1.25"): 10mm & 25mm
      Parabolic Primary Mirror
      3-arm Secondary Mirror Spider Support
      Red Dot Finder
      Wooden Alt-Azimuth Mount
      Collapsible/ Extendable Tube Assembly
      Weight Approx 7.5kg
      Supplied with Gift Box
      33% more Light Gathering than 130mm
      Skyliner 150p:
      Magnifications (with eyepieces supplied): x48 & x120 Highest Practical Power (Potential): x306 Diameter of Primary Mirror: 153mm Telescope Focal Length: 1200mm (f/8) Eyepieces Supplied (1.25"): 10mm & 25mm Parabolic Primary Mirror 0.5mm Ultra-Thin Secondary Mirror Supports 6x30 Finderscope Direct SLR Camera Connection Wooden Alt-Azimuth Mount with Accessory Tray 73% more Light Gathering than 114mm Many thanks!
