DMC Posted September 6, 2011 Share Posted September 6, 2011 Can anyone tell me how many degrees the Pleiades cover in the sky. I am looking for an ep that has enough tfov to take it all in one go. Link to comment Share on other sites More sharing options...
spaceboy Posted September 6, 2011 Share Posted September 6, 2011 2.0' but it looks far more impressive in a set of bins. Link to comment Share on other sites More sharing options...
DMC Posted September 6, 2011 Author Share Posted September 6, 2011 Thanks Spaceboy. I bought a pair of 10X50 bins recently from Lidl. Haven't had a chance to try them out yet but probably won't be much addition at £18. Link to comment Share on other sites More sharing options...
Polar Bear Posted September 6, 2011 Share Posted September 6, 2011 A 50mm EP with your 200P will give you a field of 2.3 degrees at 24x magnification.Have a play about with this great calculator.N.A.A. Telescope Math CalculatorPaul Link to comment Share on other sites More sharing options...

Telescope Math CalculatorPaulIt is highly unlikely you would be able to fit the whole of M45 into the FOV of an EP in the 200P. Due to the huge exit pupil using a 50mm EP it would be pointless as most of the light would be wasted. As mentioned before, binoculars would be your best option.

themos Posted September 7, 2011 Share Posted September 7, 2011 With the Pleiades as bright as they are, you can afford to waste some light. Link to comment Share on other sites More sharing options...
spaceboy Posted September 7, 2011 Share Posted September 7, 2011 But would it be worth wasting the money on an EP you would only really want to be using on one object ? Just MO but I'd rather put the money towards a set of bins. Link to comment Share on other sites More sharing options...
themos Posted September 7, 2011 Share Posted September 7, 2011 Well, I certainly haven't spent money on a 50mm e/p so I see your point. Link to comment Share on other sites More sharing options...
Simms Posted September 8, 2011 Share Posted September 8, 2011 Agree, I much prefer viewing M45 through my bins than my scope - although looking forward to taking a crack at imaging it this Winter. Link to comment Share on other sites More sharing options...
