Sounds like you went straight for astro-photography My advice is to always do at least 6 months of visual observing before plunging into AP That will teach you to align and find objects and what to expect when you are imaging The red dot finder probably won't do much. And the WO scope is great for wide field AP but not that good for observing most astronomical objects Just wondering if you have a diagonal and any EP's?

Yes barlows tend to make your setup stick out. Consider a shorty barlow, I use a 2" astro-physics barlow that is nice and short

Go the 6" for the increase in aperture and better mount. You can always upgrade the EP's later Make sure the item is in stock due to supply problems from China

Sounds like you got a good deal. I have the ES 14 and 9mm 100 degree EP's and they are brilliant
