what is the largest field of view eye piece for skymax 127 f/1500

[John]

Because the scope is limited to 1.25" eyepieces the widest / largest field of view would be given by a 32mm plossl or a 24mm wide field such as the Hyperion or the Panoptic.

Such eyepieces used in the 127mm / 1500mm focal length mak-cassegrain will show a true field of view of 1.1 degrees which is a bit more than twice the diameter of the full moon.

This is a great tool for pairing eyepieces with scopes from a FOV point of view: http://www.12dstring.me.uk/fov.htm

Click on the red link "switch to visual view", select your scope (or the closest you can find on the list), select an object (The Moon is a useful benchmark) and then select a range of EPs from the drop-down list.

Hours of fun when it's cloudy

It will depend on how deep your pockets are.

A plossl at 30mm will give the same as a BST at 25mm, however a 25mm Antares W70 will give more then either.

None of those are really expensive.

Looking around the ES82 stop at shorter focal length so can ignore those.

Not sure about TV and other brands.

From a quick look the Antares W70 25mm would give 1.166 degrees, a 32mm plossl 1.066.

The comments above are all good.

Is there anything in particular that you are trying to view, eg getting the Pleiades in a single FOV ?  I just accept that a restricted FOV is a constraint of a 127 MAK, but one that I can live with. I am happy with the quality of view through the BST 25mm, which in itself was a jump up from the stock equivalent. Personally I would not see paying for an expensive EP to get that little bit extra as good value.

I would see (wanting a wider FOV) as nature's way of saying; you are now ready to get another scope.

I cannot get all the Pleiades in my 7x50's - apart from the six (seven when viewed optically) main stars.

That sounds strange.

I would have thought that you had a FoV of around 6 degrees. Mine are givena s 6.2 degrees  (I think) 330 ft at 1000 yds I think is the specification.

They are 8x42's. The Pleides are given as just under 2 degrees.

I cannot see your 7x50 being less then mine and even if they were 5 degrees (unlikely I think) then you still have a field that is 2.5x bigger the then Pleiades.

To get the widest possible field from my 6" SCT (accepts 1.25" only) I used a 32mm GSO Plössl for a while. That worked, but I get much nicer views from the very crisp 24mm Maxvision. At €79,  the 24mm 68° Maxvision is a true bargain. 

You can use Stellarium to get an idea of how much sky you'll see with any eyepiece/telescope combination. Just activate the Oculars Plugin (Configuration> Plugins> Oculars> Load at startup) and restart Stelarium. Configure the plugin with the telescopes and eyepieces of your interest and compare the views.

It's easy and quite accurate. Here's what a 1500mm focal length telescope shows with a 24mm 68° eyepiece:

I have the Antares 25mm W70 (performing sterling service as finder EP complete with cross-hairs I inserted, in my 14x70 finder). Its FOV is as big as it gets in 1.25" fitting, but the quality pales compared to the MaxVision 68deg 24mm, which I use in my solar set-up and travel set. The MaxVision 24mm is a really good deal at the moment. Not perhaps Panoptic quality, but (although rated to perform well down to F/5) it performed admirably in a 20" F/4.1 Dob, better in fact than the (granted: cheaper) Antares W70 in an F/5 scope. In your slower Mak the differences will be much smaller, but the MaxVision is much more future-proof than an Antares, I find
