Space Hopper Posted December 16, 2022 Share Posted December 16, 2022 (edited) Hello all. I've been umm-ing and arr-ing over astigmatism correctors for a while now. I'm currently 55 and have 'distance' glasses for driving, but i've never used them for astro, and don't really want to go down that road if i can avoid it. When i look up to the stars without glasses, the stars look a bit contorted : no longer what i'd call sharp points of light. Looking through the scope, its a little better with good focusing, but i often feel my own worsening eyesight is the weakest link here. I often blame insufficient cooldown or poor atmospherics, but maybe its my eyes that are the real issue. I only have the one scope : an F7 refractor with very good optics. I binoview most of the time, and currently have pairs of Tele-vue Panoptics in both 24mm and 19mm. These are my main 'workhorse' eyepieces and they get the most use. I also have a single 2" widefield : a 35mm Panoptic. Dioptrx is compatible with then all, although i'd need adapters for the 19 & 24s Out of interest, i also use a 12.5mm Noblex (Docter) for single eye viewing, which is exceptional. But is this due to its 'anastigmatic' design, or something else ?? My latest prescription lists the 'cylinder' -0.50 left eye and -0.75 right eye, so fairly weak correction is needed. For mono viewing with the 35 Pan, or whatever else, i always use my left eye. My left eye is my better eye. I'd be interested in hearing anyones opinions here, and i apologise in advance if this topic has been covered in detail already. Are there any issues using then for bino-viewing ? I realise the eye-lens and eyecup will be bigger with Dioptrx installed. But my IPD is a very average 66mm and my nose is also pretty average in size, and i find binoviewing an easy pastime. And would i be better off getting a slightly stronger option : say 0.75 and 1.0 so i can 'grow in to them' as i assume my eyesight will deteriorate slowly in time ? I've quickly shopped around online and 365 Astronomy seem to be the best option price-wise (sorry FLO 😉) Thanks in advance.
