I didn't realise how nice the sky was tonight and instead of doing some observing I watched TV, anyway, I snapped this with my GF1 and Minolta 50mm lense.

and to make sure it was what I thought it was....

Hi,

It was a Meade 32mm super Plossl in a Meade 105etx. I actually didnt bother scanning the area much just left it centered and reckon Atlas and Pleione were just out of view. They may have squeezed in if I moved the scope across a bit. Perhaps subconsciously I was telling myself I need a wide view scope like the Startravel 102 which I had been thinking about :).

The Meade 32mm Super plossl has a fov of 52 degrees. I'd imagine that is plenty of room to fit the whole of the group into the same fov. I'm sure that i was able to do it with a 32mm plossel that only had a 50 degree fov. IIRC it was a tight fit but possible.

If I am right the focal length of the ETX 105 is about 1500mm. This means you have about 46.7x magnification and just 1.11 deg true FOV. My C8 equiped with a 40mm super-wide angle (Paragon) yields a 1.36 deg FOV at 50x, which can just about hold the Pleiades (with no room to spare. A 100mm F/5 travel scope with a 31mm Ultra-wide such as the Nagler would yield a 16x magnification and 5.08 deg FOV. My 80mm F/6 manages 5.3 deg FOV at 15.5x with the same EP.

Short fracs rule on these big objects!

LukeSW you had me worried that I may be loosing it and had the 26mm in at the time. Micheal you seem to back me up !! Anyway your both at a lower altitude than me as I'm on top of a hill therefore a bit closer so every object is going to look a bit bigger :):):)

The Pleiades is lovely to look at through a wiefield frac... though I managed to see the nebulosity the other week for the first time through my RC Astrograph of all things!

I like the fact that Stellarium has it listed as a nebula :-) I thought it was primarily an open cluster 'with associated nebulosity'?? :-)

Nice thing to look at either way!

Indeed it is. 31t5 in my Astrotech 106mm f6.5 gives a 3.6 ish degree fov. Perfect for the Pleiades. Pin sharp stars and lovely contrast mean this is my favourite way of viewing open clusters of this type.

The double cluster looks fabulous too

Cheers

Often people see the nebulosity without realising it, they mistake it for flare. Wonderful target when viewed through a widefield refractor. Interestingly when observing Pleiades it appears cultures around the world all independently created stories about them that included a number of women, like the Seven Sisters.

Don't go for a 40mm Plossl. Once you get beyond 25mm the 1.25" eyepiece barrel starts to restrict the view. A 40mm would give you the same FOV as a 32mm, though the object would appear smaller. This is why eyepieces like the 24mm Televue Panoptic and Baader Hyperion are so popular, they give you the widest FOV available from a 1.25" barrel. It might sound strange but a 24mm Hyperion, 32mm Plossl and 40mm Plossl will cover almost precisely the same area of sky.

I have the Hyperion Zoom but I still can't see the full Pleiades with it at 24mm which is why I wanted to try something different. Although I haven't tried the 90mm frac out yet, the viws with that might be better.
