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)?
Good day fellow gazers at the sky! I recently joined and i would just like to say how wonderful everyone is (a special shout out to George Gearless)!
Can anyone suggest a good reflector within my budget shown in the title? While i'm here i'd just like to say about the app, Nightshift. It is proffesional, clear and tellls you when to observe, and what you can see, for the next year! It also pinpoints your location exactly, so it is really accurate.https://play.google.com/store/apps/details?id=com.waddensky.nightshift. Anyway, that's me done! Thank you all so much for your time

So I am fairly new to the hobby, what I mean is I have a Celestron Astromaster 114 right now but its hard to use because of the non computerized equatorial mount as well as the red dot sight is bad. I am mainly interested in looking at DSO’s because they seem very interesting. My question is should i get a refractor or sct for observing dso’s and sometimes planets? I want a computerized one with tracking so I don’t have to take a long time finding nebulae and galaxies. Also, is there a certain type of filter to see color on nebula when not using eaa and just viewing with your eyes? I am looking to spend between $600-900
TS Optics Photoline 90mm Triplet
On reflection (or should that be through the lens of reality?) this was overpriced at £800, so is now reduced accordingly
In excellent condition, I gave a small writeup about this when I bought it, and it is still an excellent scope. However it has been losing out to the 60 and 76 Tak and now spends all of its time alone, safely flight-cased.
Don't leave this scope to suffer a lonely and unused life. Buy it and catch some great views this winter!
