new boy images

[astroboy]

Hi guys , girls and others.
Ive just signed up and thought i would post a couple of images taken with my fav' setup .
I usualy use a G11 with a moded Meade 10" Schmidt Newt which gives a more corrected and flater field . also makes it F3.5 instead of F4.and gives good coverage up to typical DSLR format .
The camera is a ST2000 and CFW8
Still got the training wheels on with the processing.

Have a good weekend

Amazing shots Zane, I love the delicate detail around the outsides.

The core is burnt out in both of them - how long were the exposures?

Another G11 user here, there must be 6-10 of them now!

They are great images Astroboy!!! Nice little toy you took it with as well, seems as though that G11 Mount puts you in that exclusive club with Ponders et al!!

[fringe_dweller]

Really Nice! :) looks like you got some nice dark skies there AB

Nice work Zane ! nice to see you've joind us here at IIS forums . :)

Thanks for your kind words everyone and hi Louie , the total exposure for M83 was 30min and for NGC2070 60min
I've put in a better version on NGC2070 that shows some better core detail and a rosette shot which was also about 60min total with Ha for the red .
The G11 is a good mount after a lot of fine tuning , Im on the lookout for somthing better is anyone has an old Tak or AP gathering dust.

Thanks
Zane

Great shots there, the field is nice and flat for F3.5 :)

Yes good shots but need more work (processing) ,something has been lost the weak nebulosity,surely 60 min total should be better than that.Check out this pic

Taken in a hurry 3x330sec Canon 300mm F2.8L Hutech Nebula filter ISO 1600.Just before dawn.
Tornado33 is correct as usual, SN cameras have a flat field.There is a lot of FUD (fear uncertainty and doubt) spread about the difficulties of collimation of SN optics.I have no experience with them.

Hi And Welcome!

Some nice shots that look like there could be even more hidden in there.

Tell me more about the modded SN10. I use a stock SN10 and a Baader MPCC.

Cheers

Hi Avandonk
I still have a lot learn about pushing the processing without it looking too fake i usually back off and have them looking a bit more normal . I agree theres more detail in there .
A normal SN dosn't have a flat field for the same reason a Schmidt Camera needs to have the film bent into a curve.
The only thing the Schmidt plate does is reduce coma by half which for an F4 is still a lot.
A guy in Japan came up with the idea of using a refractor objective infront of the camera , in this case a Borg 50mm F10 ED which helps alot . moving the corrector 400mm up the tube improves thing further still. Let me know if anyone wants his website.

I also replaced the focuser with a CR2 , a great focuser.
I don't have a problem with collimation in the currant set up it was when I extended the tube 400mm and had to use a spider to get the diagonal in the right place the spider wasn't up to holding an 80mm diagonal. Doing this halves the coma giving a well corrected field out to 35mm format.
Thanks for your excellent shot of the rosette , how old is your Canon 300 F2.8 I had thought of buying the new model which is excellent but expensive. Although I had a guest here that uses the 600 mm F4 ( I think he has deep pockets ) with great results.
Thanks everyone for your input and kind words.
