I own a new bintel DOB BT 202: Aperture 203mm, f/5.9, 1200mm Focal length.
Bintel 30mm wide view, Plossl 20mm, Plossl 15mm, Plossl 9mm.
What would you recommend be my next purchase?
Should i go down the Barlow path? I realise this may open the gates to many suggestions but was hoping there may be an obvious next step. :)
I have the same scope and the eyepieces that came with it.
I wanted more magnification for Saturn and other planets, so I bought a TV Delos 6mm as that's about the maximum magnification the scope can handle. So far I haven't been able to use it very often, the seeing in the suburbs isn't up to it.
Since then I bought a secondhand Pentax XW 10mm and I'm able to use it more often. It is notably better than the 9mm Plossl that came with the scope.
I think my most used eyepiece is the 2" Superview 26mm that came with the scope.
So if I was starting over again, maybe a good quality 10mm wide view such as a TV Delos 10mm or a Pentax XW 10mm.
A zoom eyepiece such as the Baader Hyperion might be handy too, the ability to change magnification on the fly has appeal.

Edmunds Optics RKE 28mm. If you don't have one. It should always be the next eyepiece you should get next until you do.
ymmv
Adrian, tell us more. What does it offer over the 26 or 30mm superview?
I don't think I've heard of it before.
OK, got over my laziness, Google says it gives floating views and has a cult following.
Thanks for the tip.

I am going to offer some alternative advice...instead of suggesting a new eyepiece I would suggest getting a good adjustable height chair instead and using what you have for a while.
There are many great eyepieces available today (we are blessed) but final preference often comes down to small differences based on the observer. It takes a little viewing time to understand what you like and do not like so I would take my time before upgrading...the stars are not going anywhere...and attend a star party or two and look through a few other folks gear to learn what you like.
Unlike eyepieces which individually will be used depending on what you are looking at and sky conditions, a good adjustable height chair will be used each and every time you observe regardless of eyepiece. I have also found that when I am comfortable I observe longer and glean more detail from what I am looking at regardless of the eyepiece I am using on the night.
As I get older I find the ergonomic improvements in a good chair make looking at the night sky even more enjoyable.
Enjoy your new scope and eyepieces that came with it...use them for a while and get familiar with what they can do and your likes.dislikes about them. You would not want to put a first time driver in an F1 race car without some practice time in a regular car...
If you feel the absolute need to buy something else new...consider the adjustable height chair, for me it was one of the best investments after the scope that I made.
Clear Skies!

If you want to go hunting faint Deep Sky Objects, a 2mm exit pupil is best as far as I am concerned. For you that means a 2X5.9= 11.8mm eyepiece, and the closest a 12mm eyepiece.
And you'd want that 12mm eyepiece to be at least a wide angle, or better yet an ultra-wide angle, which make life a lot easier when pushing a dob around.
A Barlow or Powermate would only really give something useful in the high power range with the 9mm eyepiece. Personally, I'd go for 4, 5 or 6mm wide angle eyepiece (perhaps a TMB). Again, I mention wide angle because the field of view will be small, requiring a lot of pushing the dob around to follow planets.

Renato
