![]() ![]() This is an excellent eyepiece for observing galaxy clusters, framing emission nebulas with the black of space, observing the nebulosity around the Pleiades, etc. The eyepiece has a soft fold-down rubber eyecup and comes with dust covers for both ends of the eyepiece. The eye relief of this six lens/fully multicoated optical system is 18mm, foe essentially unvignetted views for those with severe astigmatism who must wear eyeglasses while observing. That's plenty of time for multiple observers to look at the same object, or for you to absorb as much detail as possible, before having to reposition the scope. This gives you over five and a half minutes of uninterrupted observing with such a scope while an object drifts from one side of the eyepiece's flat field to the other. For example, it will give you a 1.43° field at 48x with a 10" f/4.5 Dobsonian, more than enough to take in all of the Pleiades at one time. You can use the calculator in the "formula" tab above to see just how wide the field will be with your particular telescope. While the 24mm Explore Scientific is particularly well-suited to observing with Dobsonian reflectors and fast focal ratio refractors (it provides a big 5.3mm exit pupil for rich field observing on an f/4.5 Dobsonian, for example), it provides "picture window onto space" images with any telescope type and is a superb eyepiece to replace the so-so 25mm or 26mm that is usually supplied as standard equipment with many new scopes. Many observers feel that a 68° field eyepiece like this Explore Scientific hits the "sweet spot" between the affordable, but "looking down a tube" view of conventional 45°-50° field eyepieces, and the full-immersion, but very expensive, observing experience of an ultra-wide field 82° or 100° eyepiece. This prevents internal fogging in the eyepiece keeps the interior dust-and fungus-free and makes it easier to clean, as there is no risk of excess cleaning solution getting trapped between the lenses. It is O-ring sealed and argon-purged to be 100% waterproof. This new 68° 24mm Explore Scientific is an excellent low to medium power wide field eyepiece with an unusual benefit.

Max users who are comfortable writing command-line code soon realize that working with the codebox operator means learning a slightly different bit of programming than they may be accustomed to – GenExpr.I think that’s because we find ourselves in a culture that privileges text-based coding, and perhaps because beginning users see others opting for codebox operators from the start and assume that it must always be more efficient. Some Max users who are uncomfortable or unfamiliar with text-based coding may worry that using the codebox operator is more efficient than the operator-based approach that they’re becoming more comfortable with (now that we’re 5 tutorials into the series).As before, one of my goals is the reduction of anxiety – and, perhaps more than any other part of the gen~ patching world - the codebox operator tends to be a source of discomfort for some beginners. In this installment of our gen~ for beginners series, I’d like to introduce you to the codebox operator. That’s what the codebox operator in gen~ is all about. ![]()
