I was out the other night when conditions were good. I had let my 6SE acclomate for an hour and had intentions to try for Sirius B. I started, however, with the trapezium. I was able to pick up E and F at about 136X. F was fairly constant so I knew conditions were good. I next tried Rigel and was able to see B at 136X and 60X. I then tried for Sirius B. I thought I saw B but it was hard to tell for sure. The trapezium really looked nice though. It was the first time I could see F with the 6SE and I was pleased....

After years of refractors from 80mm to 105mm and only 4 stars in the Trapezium, I finally was able to see E & F thru my Discovery 10" f/5.6 Dob tonight. The full Moon(I think)was rising in the east thus the sky was slowly getting brighter. I still managed to use my Televue 10.5mm Plossl at 135x with E & F easily resolved. Its been a long 6 years since I last saw them.

You just need to catch them on a moonless night with good seeing and good transparency at a dark site. Then it's easy.:grin: Mike


You mean buying a car is easy if someone else pays for it? :roflmao: Anyway, seeing here in Mid- TN is bad at best most of the time, or so it seems. I have been trying for the last several days - the days that aren't clouded over - to see more than 4 in the Trap. I am beginning to think someone moved my house to England while I slept! :)

I use to have a Meade 826C 8" F/6 reflector & I always saw E & F with Meade 10.5mm & 7mm RG Orthos working at 116x & 174x in magnitude 4 skies.

Recently I split the six Trap stars with my C6 SCT under decent seeing. With an XO 5.1mm in the focuser for 294x, I could see the E and F stars. E was visible nearly all the time. I could see F for over half the time. My Baader Classic Ortho 10mm at 150x still showed the E star fairly consistently, but F was only glimpsed now and then.

So it's not that difficult for a 6" telescope - even an SCT! :grin: - to split the Trap's E and F.

I think seeing E and F is much more related to seeing if you have decent optics. I've been able to see it with my 4" refractor on multiple occasions. Though I remember the first time I saw them in my 10" dob on a good night about a year ago. All six stars glowing like little diamonds. Very exciting.

Then there was that night when I tried to see the trapezium at a dark sky site with that same 10" scope. Couldn't see E or F to save my life.

Yes, at my dark site it's dependent on the seeing whether or not I'll see E and F with my 10" Dob.
