Some DSO's

[beren]

Gday some pics taken in the last week or so , equipment used a nikon D70 DSLR with 17-70/70-300 lens and a 80mmED refractor on a CG5ASGT mount {unguided at the moment}

Nice work Beren. What kind of exposures times are you using to get those results?

[beren]

The first M42 pic is a combined 15x240sec , 240 sec was around the limit for the night without the frame getting satured with skyglow with the ISO rating set at 400 uisng a 300mm lens.The NGC3372 pic is a combined 5x200 640iso 300mm lens.With the 80mmEd I sometimes use a IDAS light supression filter that helps push the exposure times out further but for the M42 shot it's only 120sec {i think :hmm: }....cheers

For 120 seconds, you captured a good level of Nebulosity on M42. The tendrils extend right to the top of the image. I'd love to see what that camera can do under a dark sky.

I'm yet to play with DSLR. Is there much of a difference in using different ISO settings with it? I noticed you used a couple of different settings.

Hi Beren,

Great work there mate. So on some of those shots you didn't even use a telescope? I'm not sure what this means "17-70/70-300 lens " but I guess it is some kind of camera lens?
:hmm:

Some good shots there Beren. DSLR's seem to have their own look and feel. Stupid question, but does the camera come with software for stacking or do you do all that in photoshop?

:thumbsupmate: thanks

Radar I've started lately to experiment with the ISO settings , i always used to use 800 mainly , I'm really a beginner in this it's all experimentation with little theory :duh: I'm trying to stop myself from trying to image everything in the sky on a given night and concentrate on one object and get as many lights as I can to help the signal/noise ratio {i use a IDAS light suppression filter to aid in the exposure times}

Hi Dellio sorry , on some of the images I just used my DSLR with the either my 17-70mm zoom lens or another one that has a 70-300mm range connected to the camera with the camera itself hooked up to a adapter plate on a tracking mount

CMT I use the program Images Plus for camera control and capture {setting focus and settings like ISO plus the number of frames to be taken } and then the same program can be used for calibration and stacking and processing .In the latest edition you can add all your lights/darks/flats/bias frames together and the program does everything automatically :thumbsupmate: I use Photoshop CS2 for final tweaking .

This is like me. I get impatient and try and shoot everything in one night. Though I am getting more methodical as time goes on.

I might be going bush later today, I have Carina, Witchhead, Rosette and Orion on the cards.

:lmao: it's hard when conditions are good not to go overboard with "targets"

Good luck with tonite i was hoping to go out past Mundaring weir tonite and try my luck but Im testing this new shoestring adapter for guiding on the Cg5 mount before i take it out into the field. The wind was a pain last night in the metro area hopefully it will ease off tonite

[Radar]

I used to use the Shoestring adapter with Guidedog software. Always handy to have an autoguiding setup like that.

Good luck with the wind tonight mate.

very nice images as usual Stuart.

WOW! Those are fantastic shots, they look great. I'm very impressed Beren...well done :thumbsupmate: :ta_clap5:
