M42 - Orion's Nebula

[hairymunky]

Had a go at Orion's Nebula the other night, with my
75-300mm tele (read some bad reviews about it, but
for me, it did what it needed to do :) )
Still new to photography (keep forgetting to set things
on the camera), and its a case of trial-and-error, with more
emphisas on error (delete, delete, delete!!!!)
Tried to tease more detail of the nebula but it became
too grainy.. will try a slower ISO next time...

M42 - ISO 1600 @ 300mm

I guess you need something considerably longer than a 300 to make any real sense of the stars ... :shrug: ... but then an astronomer I'm not ... :D

There will be a lot of noise at iso 1600 but amazingly noise appears in different places in individual exposures. Take multiple shots, layer and reduce transparency by half with each layer. Mask out bits that need to be sharp, Sounds complicated but may help you make your space "blacker". HTH.

Or optionally try this http://startrails.de/html/software.html

Take one shot of the sky (in this case) then put the lens cap on and take a few more at the same settings. Stick 'em in the program and it should (it's not quite what the program was designed for but it should work, the shots with the lens cap on will be the dark frames) do it all for you. :)

I've shot the Orion Nebula with a 500mm focal length refracting telescope, with a 1.6crop body (I'll try and dig the images out), with some success it's a huge object and the nebulosity shows up nicely, as has already been said stacked images help alot as does a driven drive and dark skies !

Thanks for the tips folks. Always been intrested in
this type of photography, and am keen to get
better images, and image-scale (more money,
bigger gear, angrier wife...)

Haven't tried dark field subtraction yet, but have used
the noise-reduction functions on the 350d. Will try
some darks the next time its clear (no chance soon.. :'( )

Still haven't figured out the ins & outs of registax yet, with
it's wavelets and stuff. Next gadget will probably be an
eq-5 or similar for the 8" dob... wife's going to love
me :nono:

Yup an EQ5 is a great bit of kit, thats what I use, they can be picked up at a pretty reasonable price and do a great job.
