This is my first part of a seven part picture.
I have to take some longer exposures and a load of shorter exposures to finish this.
This picture is a stacked set of 117 5minute exposures without darks or flats.
I still have to take the darks and flats.
The good thing is that my 40D's cooling stay's on -12.5 almost constantly during the whole night and was still on -12.5 this morning at 7:00 am.
Did 80 images last night of 5 minutes and only had to throw out 12
Lucky for me is that the scope and camera does not hit the legs of the eq6 mount when going thru the meridian and keeps tracking very well.
So this is part 1 of the overlay i am going to make.
Comments welcome and tips too.
Very smooth looking! as you'd expect for 117x5min subs!!
Do you plan on doing some longer subs to really bring out the faint gasses surrounding M42? and some shorter ones for the core?
Thank you Alex
Yes i want to do 10 and 15 Minute subs tonight and some 1Min 30Sec and 10Sec subs in the early morning.
Then i have 6 parts and then have to decide if i want to go 25Min and/or shorter than 10Sec.
Have to wait and see (could be getting a 8 part pic ).
I reckon 15min subs will do it for sure! I look forward to seeing it completed..
Is it greedy of me to think that with $900M euro's, I'd bust out on 90x Canon 200mm F/1.2L's, and 90x STL11000C's, a giant EQ fork mount.. Have 10 groups of 10, each group would point at the exact same spot, and adjacent groups field of view would overlap each other by 10 arc minutes. take 1x10min exposure per individual camera/lens, you would have a 9 panel mosaic with 10x10mins per panel, a massive field of view you could probably get a very deep image of the entire night sky in about an hour.....
Thats an amibtious project, I admire your perserverance (9 hrs already !).
If thats going to be your midrange exposure, theres already quite a lot of neb extention, double or triple the sub time will be very deep.
For no darks or flats, that also has some fine smooth detail, exceptionally good processing.
Blending shorter exposures to provide smaller stars overall, and stop core blowout would make this project a potential DSLR classic, given the quality so far. Hope your PS skills are honed to do the multiexposure times justice, it will be a challenge.

That would be - INSANE!
Wow.. Off topic or what!
Wow!! that would be nice and save a bit of time

I have done a early M42 about a month ago and layered about 5 layers but with a lot less exposures so it looked a bit grainy but the trap was visible
That looks cool Martin. I wanna do a mosaic of Orion too when the clouds go or when I move in SA. Whichever comes first. Make sure you get registar to stitch all your panels. Easy as. Great start!

I think its multipart exposure times Martins talking about Marc, not a mosaic

!? Didn't read properly then. Just saw the word 'mosaic' got excited and thought 'yay! I wanna do that too!'. Still moving to SA though if this weather continues
