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!!

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.

How heavy is it to carry?

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?

      Hey all,
      I'm considering the 250PDS. The main use is visual, and the second is EAA (I currently use a zwo183mm). 
      What I'm hesitant about is the primary focus. since It's mostly for visual, I'm wondering on how much back focus it has compared to the standard Skywatcher 10" dobsonians? with the standard dobsonias with the same optics and focuser you already need an extension tube for most eyepieces...
      Also, there's probably a "bigger" obstruction (bigger shadow on primary)?

      I have a SkyWatcher AZ-EQ5 mount. It’s all working fine, except I have an issue with alignment. This applies whether I’m in EQ or Alt-Az mode.
      I set it up using  one or two star align without problems.
      However if I use the handset to GoTo another object, I usually need to do fine tuning adjustments to centre on the new object. But the mount disregards these adjustments, so if I use the GoTo system to centre on a nearby object, or revisit the original object a second time, it’s still off by the same amount.
      How do I tell the mount that I have centred on the new object and that it should now be aligned with that object ? 
      My iOptron MiniTower has a feature that does exactly this – once set up correctly and aligned, for each new object I go to there is an “ALIGN” option, and if I use this it now knows the correct position. Can I do this with SkyWatcher and Synscan ?
      Thanks. Angelo

      Hello
      I am new to astronomy, and recently purchased a Celestron Starsense Explorer LT 114AZ, and just for a start, I used the finderscope to locate exactly a random star, and I looked through the eyepiece and just saw a blurry white image. I was using a 25mm eyepiece lens, and then decided to put on the 2x Barlow lens with the 25mm lens, and nothing changed. Is this normal? What should I do to improve?
      Thanks.

      Hi, I've got a Skywatcher Heritage 130p reflector, and if i insert anything less than 10mm eyepiece, the image won't get crisp. I guess it's normal, but as I'm very new to astronomy, I'd like to know what the sharpness depends on exactly. 
      Is that the focal length (how fast the telescope is? ) or the size of the mirror and how much light it gathers? Or both affect it the same way?  
      Are things the same with refractors in this regard? Thanks.
