My main DSO
kit consists of Pentax XW 5,7,10,14,20mm, ES68 24mm, Baader Aspheric 31,36mm and RO Plossl 50mm
All except 50mm Plossl have ~70 deg FOV
and ~20mm eye relief and I like to keep it that way.
Most of them are spaced by 1.3-1.4x (which I am aiming for) except XW20 - ES68 24mm and Baader 36mm - 31mm pairs, which are too close for my liking. As a result ES68 24mm and Baader 31mm don't get used much.
It just occurred to me that TV Panoptic 27mm would fit perfectly between 20mm and 36mm, and thus could replace 24mm and 31mm in my kit. Any particular reason I should not get?
