Hi Coffeecup25,

It may help other people to better answer your question if you were able to give some idea of the budget you have.

Part of the catch is that the field of view is dependant on the magnification, with a longish focal length the field of view will always be towards the narrow side.

You have 1200mm FL so if a BST at 25mm and 60 degree you get 1.25 degree, a 32mm or 40mm plossl will give no more.

Not sure what the Panaview's are like, they are 2" fittings.

For f/4.7 you may need a good quality one, a 32mm or 40mm TV plossl is £100 to £110.

ES 82 are the next thought at £140, there is an ES 70 degree: 30mm at £87 or 35mm at £105, Telescope house.

So what budget and how wide a view do you want?

1 to 1.5 degrees will get M42 and M45 in, not a lot will get all M31 in view - for that buy another scope.

Thanks for the help
