First CCD image

Hi everyone

this is my very first image using a ccd camera...

i reckon it looks okay but i feel that there is more to be unlocked in shots such as this..

Exposure: L600, R600, G600, B1200 seconds
Meade 10" LX200 Classic with Lumicon Giant Easy Guider & Focal reducer set @ f4.5

SBIG STL-11000M

Any constructive tips and tricks would be very much appreciated

Hi Benny.

Use "Manage attachments" to browse to the image on your computer.
Make sure it's under 150k jpeg and around 800x600 px in size so it won't need too much compression.

not bad! different colourings to what I am used to with the DSLR, but it certainly has the desired effect.

Great stuff Benny. An excellent first CCD image!

I reckon there is more info locked away in that image too given your exposure times and the camera you used. What processing did you do?

One thing I learned quickly is to gather relatively more data in the Luminance channel because that's where all the detail will come from in your final image. Also be aware of the varying sensitivity of the SBIG 11K at different wavelengths - ie it's nearly 2 times more sensitive in the blue than in the red so you need to compensate for that either when you're colour combining or determining the length of your exposures. That will help your colour balance too.

Maybe use your Tak next time??

Cheers, Marcus

Excellent start Benny. Nice mount you have there (though I'm bias)

As Marcus mentioned, you'll need to work out the colour balance for your imaging set up. The KAI-11000 chip peaks in the green wavelength so you'll need to compensate for this. Also, I think you could stretch your data more to bring out fainter detail.

I find it interesting that out of the three telescopes you have, you selected the 10" LX200 classic that is going to have inherent field curvature even with the focal reducer. Perhaps try the LX200R or TSA-102 with the STL. There are not many telescopes on the market that will fully illuminate the 35mm chip and provide pinpoint stars.

Totally agree with you guys... I have had the camera about two weeks and most of that time was spent reading the manual and familiarising myself with the software that SBIG had provided...

The reason that i used the 10" is because ive been too busy to set up the 14" and the Tak, with the mount as i have only had those for a very short time as well. it's all still in boxes lol

As far as the image was concerned the only processing that i did was to subtract darkframes and a little bit of adjustment in photoshop. it was a bit of a rush job as i was itching to see what i had

according to the different things i have read i have plenty of over head as far as exposure is concerned (i.e stacking exposures etc)

The longer exposures i do the better the camera seems to cope with noise issues as well so i might try some 10-20 min exposures when the cloud clears in the next couple of nights.

Thankyou all so much for your input so far, and i'd love to hear more from you all soon

Benny you got there, not a bad effort at all for a first attempt.

Cheers leon

Hi Benny, a nice first attempt and as you say there is probably a lot more in there as well. That is a very nice camera that you have and you will definitely get your moneys worth from it.

Excuse the silly question but which nebula is that?

Cheers

Hi Benny

Youve got a lot of gear there ;-). Id like to see a pic with the HGM Titan, 14" OTA (naughty, NOT an RC, say real RC owners, but I know what you mean, LX200R will do) and ST11K, guiding will improve thats for sure. Youd then have a dream Narrowfield rig, yay, go narrowfield.

Or the tak if your a WW (wide field wooze).

Then gather lots of subs and bury yourself in Photoshop for a few weeks, you have the capability there for some awesome images.

Nice pic, well, for a 1st light ,at least it works. Its a steep learning curve with the start youve bought youself.

Expect harsh critique on your images from now on, they should be good with that gear hehe.

Cheers

Hi Benny

A bit of a stretch shows a lot more Nebulae

Cheers

Harsh Critique??? bring it on! it will only make me better at least by the sounds of it i am on the right track... I used to love wide field as i am used to guiding by hand, but no a whole new world has opened up for me..

My Dad used to be an astrophotographer at Perth Observatory and I still marvel at the stuff he did when he was there. I can see us having many-a-shoot off in the future..

I will post a pic of the setup when i get around to putting it all together. i still have a bit of reading to do before i put everything out of the boxes though. i was all like when i got the 14" delivered

Ta Benny, I looking forward to more images from your setup as well as your setup itself.

You're off to a good start Benny !
Well done on you're first shot with the SBIG camera.

Looks like there's more detail to glean from that frame.
Using PS to correct the colours somewhat and stretch the histogram I got this result.
Obviously there would be heaps more detail in the original frames and it's got great potential.

Well done once again.
