    Default Panoptic 24 mm or 27 mm ?



    Hello,

    I currently need to purchase a wide angle eyepiece for my 10'' Dobsonian with F/D=4.7.

    I hesitate between Televue Panoptic 24 mm and Panoptic 27 mm, could you give me an advice to choose between the two?

    Many thanks
    Eric

    They will both be excellent eyepieces. If I'm going wide angle, I want wide angle, so I'd go for the 27 mm.

    Thank you,

    Do you think I will need more a Paracorr with a 27 mm than with a 24 mm ? 3 mm should not be so different ...

    In my f/4 scope, the Panoptic 27mm almost doesn't need the Paracorr. Though the Paracorr does make the image awesome right out to the edge, the deterioration without it is minimal.

    I preferred the 24 Pan instead of the 27 Pan. In my F4.8 dob, the 27 Pan pin-cushioned a bit towards the edge giving you that vertigo feeling when panning around. The 24 Pan seemed to handle it better than the 27Pan and the wide angle didn't seem to be much of a difference IMO.

    I don't have a 24mm but do have a 27 mm Pan. It was my first TV and it is a fantastic eyepiece in my 12 " dob. It sold me on geting more TV eyepieces. It is the eyepiece that gets the most work as a finder, scanner and viewer of most DSO objects. I prefer the views of the planets with the 27 mm, they are sharp and clear. Can't beat that "swimming in the sky" feeling from the Pan.
