View Full Version here: : M16: Eagle Nebula - 23rd June 2012
27-06-2012, 12:05 AM
Another from Saturday night, this time The Eagle Nebula. 25 mins exposure, 5 x 5 mins at ISO 800, 5 x 5 min darks, captured in Backyard EOS with the Canon 1000D, EOS CLS Clip filter, using a Skywatcher 200mm newtonian reflector on an HEQ5Pro mount. Temp was 4 degrees C on the camera sensor, but there was some noise, probably from the cables....
Stacked in Deep Sky Stacker and processed in Photoshop CS3. I hope you enjoy this one. :)
Not as much SNR as the M20 one, but it'll do for now....resized to 1024 x 680 and saved as JPG for IIS.

Ahh, yes, Mike, sorry, its still syncing to drop box. Should have finished by now. I hope.
Edit: Nope, it was busted, reloading the image now.

:) I'm not used to seeing it from that angle.
Nicely processed Chris and good detail for the exposure time.
the liink worked for me

I tried to set the camera to a known position so I can try out some flats later on from inside. Trouble is, the orientation is all screwy.
Thanks, I'm glad you liked it.

Working now...Quite tight stars and some good detail in the pillars evident, bit more data needed I guess, dark skies might help too?

Yes, it does need more data, something like my M20 54 mins of 3 min subs, (shameless plug intended) ;)
This was from the backyard, so yes, the skies were quite polluted, but the CLS filter was in and custom white balanced so the colours and processing were easier to balance and more realistic on the subs coming from the camera instead of blue tinged, which was good.
The tracking and guiding was singing for what it is, I had to insert 60 second pauses into the capture schedule in Backyard EOS to cool the sensor and also allow me move as the concrete the scope sits on is like a shaking shack if you walk anywhere on it while an image is running and the bloody dog kept chucking its tennis ball around and ruining some subs. grrrr BAD DOG!
The Bathinov mask helps a lot with the focus too, soooo many times in the past I have wasted subs because I couldnt focus properly, now its a doddle! Money well spent!
Might be time to dust off the ol' pier plans again me thinks?
