Hi Suzy,
Thank you for your comments. When the post was first made, I was unsure of what exactly I was after. However, with further research I've become clearer as to what my actual requirements are.
At this stage, I primarily interested in a wide FOV. To this extent, I currently have my eye on a Nagler 31mm, but I am concerned that under my relatively light polluted skies of suburban Perth, that the contrast would not be up to par.
Does anyone have any experience in this regard? I suppose I could go as low as a 20mm Nagler but I do not wish to sacrifice too much fov.
As stated in my original post, I have a f/7.5 refractor with a focal length of 900mm. Oh, and I am 26 years old
