Thanks Gary,

Yes that what I think anyway...like I said the images were taken over a few different nights so the darks I originaly took may not be perfect..anyway your not suppose to point them out...lol

Nice shot Tony...looking forward to seeing many more from this beast of a camera mate.

Thanks Louie,

I did mask a less exposed imaged {20 seconds} to see the trapezium but the image I used was still overexposed but much less then the 5 minute exposures I used for the image.

Thanks for your help on this.

Tony,try selecting the Trap area with a magic wond or one of the other marque tools,expand and feather the area and then use curves to lower the intencity until the trap stars are revealed. (Mid slider in Levels will do the same)
Don't worry If you go too far because you will use the Fade Tool in the edit menu to get a more pleasing blend.
I think that If you find the right amount to feather you will get a good result asuming that the exposure you are using is not saturated.

Thank Louie,

I'm having a play now.

Great first image. Your right these large chip ccd's demand alot of your equipment, skills and processing time compared to DSLR but the final product is worth it. Clear skies Ken.

tony keep at it,you,ll get the hang of it, proccessings the hard part, the stl11000 will leave the dslr,s in its wake,
looks like you have a issue in your tracking though..might need to do a drift align maybe?Me myself i have a stl11000 coming..gonna use it with me titan 50 and taka fs102 and by the way HELLO EVERYONE THIS IS MY FIRST POSTING ON THIS GROUP CLEAR SKY,S TO ALL ROB

Thanks Rob,
Just curoius where you see the field rotation..are you going off the Orion image or vignetted horse image.

The horsey has a large amount of Vignetting/coma and filed curveture due to the reducer...I cant see any rotation in my Orion at F10.

Even though I dont think I have a perfect polar alignment I would just like to know what your going off.

Octane (Humayun) · #31 28-11-2006, 07:34 PM

Tony,

That really is remarkable.

A sure sign of things to come.

I can't wait.

Regards,
Humayun

Lookm im no expert by a very very long shot but what i noticed in your m42 is that your stars are not all perfectley round,ie they are elongated a bit from top to bottom.Almost like a dec or ra drift.How did you proccess it and how many images did you stack?i am not critising you just trying to be constructive...thats how we all become better. i should know ive got a LOTTTT to learn.....
regarding poler alignment i have spent lots of hours with the ccd perfecting it and i think it is one of the most important thigs to do...just takes a lot of time! cheers all..

Striker (Tony) · #33 28-11-2006, 10:07 PM

I'm not knocking you.

I am only noob too all this stuff.

but I would have thought this was PE more so then drift...thats all.
I can see while autoguidng I do have movement up and down which I am trying to adjust.

Any help is appreciated Rob.

Its cool anyway maybe you need a guide scope with a simuler f ratio to your main scope...anyway as i said im bouncing around with plenty of my own probbs,,,,you are not alone!!!!

Striker (Tony) · #35 29-11-2006, 08:47 AM

I'm guiding with the internal guider at 2500mm......lol

I think seeing has to come into it aswell as I am imaging 15minutes from Brisbane City.

I did improve pec a little last night but I still have more to get rid off.

I think you can make yourself go crazy if your after perfection......lol

atalas · #36 01-12-2006, 06:30 PM

Tony,one thing you should keep in mind is that guiding at such a long focal length you are bound to chase the seeing ! a lot of people have reported great results with a short focal length guide scope and myself as well at times and that could be because there is less chance of chasing the seeing .

Striker (Tony) · #37 01-12-2006, 07:09 PM

Thats my thinking too Louie,

I will see how it goes guding through the ED80 once I get my guide head...but that could be a long way away....might even be late january.
