    Default What power eyepiece do you use when viewing M42



    I've been trying to see which eyepiece I have would give me the best view of Orion's nebula and would like to hear what eyepiece other more experienced people use when viewing the nebula?

    My two best views thus far were with Celestron 32mm EP with no Barlow for a nice wide shot and for a closter view my Zhumell Z100 9mm, again with no Barlow.

    I won't bore you with the math, but of the eyepieces you have, the 12.4mm Plossl will almost get M42 in the eyepiece… edge-to-edge.

    Jazzin, Sometimes I think the eyepiece is a personal choice when it comes to the various objects, and how they wish to view it. I get a lot of pleasure looking at M42 with my 13 and 17mm Stratus eyepieces. Of course, a lot of the viewing you do is dependent on the seeing conditions. If you have calm, dry atmosphere to look through, then I am sure higher powers are going to reveal things much nicer. My suggestion is try various eyepieces until you find the one that gives you the most viewing pleasure. Caley

    I enjoy a nice wide view of M42, and rarely go below 30mm on this target.

    Depends... I'll start with either my 26 or 40mm. With the 40, the field in the Kson is almost 3° !! The entire nebula complex fits inside! Then, after wandering around for a bit, I use a 10mm Plossl to zoom in on the Trapezium area. With the 150mm, the 4 split clean and bright, with the 102mm, I can see the 4 stars, but they will merge with poor seeing. But I get more nebulosity surrounding them... *sigh*
    Great target to try out just about every EP you have. There's so much to see at all kinds of different scales that, you really can't go wrong.
    Pity we're losing him for the year. I still have 3 M's to acquire from that region and it looks like it will be at least late fall before I can grab 'em for 110 award.

    Good Luck!

    I like the Orion Nebula at just about any magnification.

    The lowest magnification that I've tried which still shows four trapezium stars is 17.8x (in my 4" refractor). I get this magnification with a 28mm eyepiece. Its afov is 68°. At this low magnification some eight Orion nebulae could fit next to each other in the view. So it sits there in the middle of the view with plenty of stars around it.

    At 17.8x when you look at the tiny trapezium, only the brightest, central parts of the nebula remain visible. I suppose this happens from staring at the trapezium's tightly spaced stars while trying to separate them. The sparating works. Three of the stars are easy, the fourth, weaker one, is a little trickier. Looking away from the trapezium and nebula, the whole shimmering cloud, including the dimmer parts, suddenly pops back into existence. It's a startling effect.

    The Orion nebula is a beautiful object at about any magnification. It's the King of Winter.

    With my 102mm Nexstar 4SE, I spend (spent) a great deal of time viewing the Orion Nebula at 73x with my 18mm Celestron X-Cel EP. It was really nice moving in and around the cloud, kind of feeling a little bit "in it". Then I purchased a Telvue 32mm Plössl EP and discovered an whole new way of viewing at 41x, more akin to taking in the whole thing at (M42 and M43) all within the same field of view, not as emersive but more contextual. Many more pinpoint stars engaged with this view. Mush less objectified, more spacial. All greatly enhanced of course, by the incredible sharpness of the Televue's optics. Cheers

    The best EP is the one that gives you the view you like best As you can see from the various responses, it's a personal thing
