Here is another humble effort from the 70-200mm @ 200mm F/2.8
Basically 6x180, 2x240secs, ISO 800, ICNR,

would like to try again with more time ? ?

A very object filled piece of sky there, perhaps a little soft, that could be due to the tracking combined with f2.8 as most lenses perform best around f8 or so ( unless it's a really expensive one ).

Thanks for posting

Right you are Clive, Yep, It was 1st light for the lens so I wasnt guiding and the Auto focus maybe a smidge off, conditions had some thin moisture up high resulting in discarding half the frames & the ones used could have been better !
I was mainly testing different objects for compositions and framing ect ! Next time, Guiding and addapting the motor focuser with hopefully better sky, should yeild a more favourable result ?

Thanx for the feedback !

Cheers !

Most 70-200 F2.8 lens are unfortunately expensive... Even then stopping down helps!

I think it's a great shot and I hope to try something similar if the weather will oblige.

Glad you like jjj & DT, all the best with at what you may try for ? I do know this image could well be improved if the gear was in the right hands ? I'm actually quite pleased with it at this stage ?

Very good Bob and there is so much going on which is why I enjoy this area of the spring/summer sky.

Good luck on future goes too!

Thanx Brendan, Ross and Darrin,
The whole area of Orion is full of very faint nebulosity which I estimate doubling my exposure length to get some sought of hold of it ? ? Then again, some Neb Type filter may be the orthadox way of capturing it better, really not sure exactly, trial and error
, eh ?



Cheers Brendan, I would like another go, longer and more subs should help bring out more features, eh ?
Have a look at this other wider field ? I also captured the Larger loop,which is a milestone as well : ) It is a stitch of two single frames, upper and lower halves @ 70mm with the same Lens 3-4 mins each !

Cheers Darrin : On this Wider field The witches head is also just barely noticeable in the top left corner, for the perspective and a challenge if the sky co-operates during the coming few months , ,



Ross, I will try this compo next time also, well as close as I can get, ive been wondering about adding in the third belt star Mintaka for a more complete aspect !? ?

Very, very pretty in spite of a little coma from the F/2.8 lens. Superb processing and colour. Beautiful.

Thanks for posting,

Your lens has the least amount of chromatic abberation at f/4 and best resolution between f/5.6-8.0.
Stopping down that much will need you to expose ~4x longer than this shot, but it may help getting a sharper and cleaner image.
I can't wait to do the same shot with near identical equipment in the coming weeks.

Just some advice from a camera nut :P

Nice large view! Good shot.
