The Trapezium Is 'Bagged' A-F Stars

[EntropyStar]

After watching Dr universe on the beeb I went outside to continue where I'd left off at the weekend. Last night I finally bagged the last star available to amateurs (so we're told) in Theta Orionis...I got the ellusive F star. A little challenge from my location (Oxfordshire) but defo there, the glare from the C star makes it tough. I'd compare the F stars faintness in comparison to the C star as like Rigel and it's companion. The F star is actually a tiny bit brighter than the E star but the glare from the C star (I found) made it harder to pick out.

Here's a guide for those wishing to give it a go...

The Trapezium, Theta Orionis

Did the same myself last night. Found the 'E' star eventually but i was a bit unsure if i managed to spot the 'F' star, didn't know if my eye was playing tricks. As you say it is right next to the bright 'C' star. Will try again soon.

I've seen the G and H stars with a 12.5" Newt from a dark sky site in Northern Vic, Oz. Takes a good dark adapted eye, and practise...plenty of practise...

I definately saw a b c d and the e was clear at 10mm but pinpoint sharp at 6mm. I could maybe see the f star, not 100% sure but I am pleased with what I saw last night. very pleased.

In the attached link provided by EntropyStar, it states that "....This image was taken with a 5 inch telescope in visible light....".

Now, I'm a little confused because i have a 10" dob, use a 25mm or 10mm plossle eyepiece but don't get a fraction of the colouring that the image shows which is supposedly 'visible light'.

Why is this?

thanks

A few weeks back I managed E & F with my 4" refractor - 1st time for that aperture, they have required 120mm at least prior to that.

I think they're meaning the image is formed from the visible light spectrum as there's an image beneath in infrared. I'm sure the visible light image is still a long exposure but they've omitted the detail.

Last Friday night was good enough for me to clearly see E & F for the first time

I've seen the a-d stars a couple of times. Will have a new challenge now. .

Seeing the E and F stars in my Dob is a good test of collimation.
