You could then complement this eyepiece with the ES8.8 which would be fantastic with your telescope on globular clusters, planetary nebulae and galaxies. I don't think it is one or the other but both and I think you'll get the most out of the 6.7mm first but since both are useful it then doesn't really matter what order you buy them in.

However I cannot comment on the performance of ES in your Newtonian but can say that I use both my 7mm and 9mm Naglers on my 10.1" f6.4 as often one is either too much magnification or just not quite enough depending on the object and seeing conditions. (I get 182x and 234x). Of course there are times when I can go a lot higher than 234x and you will find this too and depending on how often this is and how much you want to observe at even higher power will be a deciding factor in whether you get even shorter focal length eyepieces.
Thanks again. I don't think I saw bands and I'mpretty ccertain I didn't see the division in the band. I was pretty confident tha my collimation was correct but iit's slightly off, could that be the issue? I've only had the scope a week and taken it out twice. I'd just like to knowiit's working properl. I looked at the mirror using my phone torch and I saw a couple of parts in the cell of the mirror that wasnt perfectly uniform. There seem to be three parts that are not uniform in the circle. This is right on the edge and the surface of the mirror is pristine. Any thoughts on how to check my scope is working correctly would be greatly appreciated. Thanks again. I like the idea of both the es pieces. Thanks again
