View Full Version here: : 32mm - 42mm EP for wider views
03-05-2007, 09:04 AM
I'm after a cheap 32-42m EP. I want one just to help me find objects easier. The wider the FOV the better. The more stars i can fit in it, the easier it will be for me to tell where i am and what I'm looking at, and where I want to move to. It will only be used as my initial EP for finding things, so I figure it would be a waste to spend LOTS of $$$ on it. Any suggestions on a low power EP, widest FOV possible, cheap cost???
I've been looking at these...
Meade Series 4000 QX 36mm Wide Angle (2") - $179 - 70deg. FOV
Bintel SuperView 30mm (2") - $79 - 68deg. FOV
Meade Series 4000 Super Plössl 40mm (1.25") - $109 (no idea what the FOV is)
Meade Series 4000 Super Plössl 56mm (2") - $159 (no idea what the FOV is)
OT30mm Ultra-Wide 2-inch Eyepiece - $129 - 80deg. FOV

I have used the Bintel (GS) 30mm and its great for the price. Will not hold a candle to the more expensive eyepieces but would be great for what you want.

Thanks Allan. Phil just informed me of that as well. Looks like a goer!

I have a 32mm Bintel/GSO wide-angle that came with a Bintel Dob. It's not perfect, but it'll do exactly what you describe. Definitely one to consider.
If you just want an eyepiece to find things quickly then I wouldn't recommend any "superwidefield" eyepiece in the 80 degree range. You will have to 'look around' to take it all in which is not what you want it for. Something in the 50-60 degree range will be more suitable.
What you are really interested in is TFOV (True field of View) which is the total amount of sky you will see.

Unlike the typical nagler experience where you need to look around to see the entire field, the Andrews UWA 30mm 80 degree field is easier to see all at once. While the view is not pretty in fast scopes, I find the 30mm UWA to be a very good finder eyepiece.

I have both the 30mm and 15mm 80deg eyepieces in 2" size. I agree in a fast dob I wouldn't bother but in f10 scope, everyone that has looked through them has wanted a set. I have been really amazed at how good they are for the money. That statement may anoy some but for the PRICE and 85% of a nagler view, they are brilliant. If you are at Astrofest Ill let you see for yourself.

If the purpose is to find objects quicker and easier, have you considered a good pair of binoculars, like say 10X50's on a tripod, and then zero in with your scope? This is what I do and it works a treat! Also when I've found the object someone else also has something to look through while the scope is in use.

I have the Andrew's 30mm 80 degree and I love it! I got mine the last time they had them on special at $99 and I use it exactly as you plan to DJ - to help me find things and just look around.
In my f5 dob or any other fast f ratio scope yes it does give stars in the outer field of view plenty of seagulling, but that doesn't take away from it's performanc eto me as a "finder".
By the way Andrews have advertised recently that if you buy any new scope that comes equipped with a 2" focusor as standard they will throw one of these ep's in for free!
