He indicates he want's it for DSO's and he owns a DOB, so I wouldn't think so given a perfect world. Considering the budget is $300 it's really in no mans land, more than needed for a narrow field of view high quality eyepiece like a plossl or orthoscopic which isn't ideal given the stated parameters IMO and not enough for a premium widefield which would be perfect.
If it was me I would be saving my money for a little bit longer and going to the next level or 2 levels higher. The 6mm TV Radian is a great eyepiece costing about $380 with a 60 deg AFOV. The 7mm Nagler T6 and 7mm Pentax XW's would be an even better option, it doesnt get much better than these. The Pentax is superior to the Nagler in some respects optically, the Nagler has a slightly wider AFOV at 82 deg as opposed to 70 deg for the Pentax. This field of view difference is an "on paper" illusion to some, as many experienced observers dont notice much difference in the FOV when looking through both eyepieces. Both outstanding, its a matter of what aspects of eyepiece performance are most important to you. Try both before you buy if possible.
