Amazing.. 30 sec on NGC2070

It's amazing what just 30 second exposures will give on NGC 2070! There's a lot of objects in the LMC which are stand-outs amongst my survey images, but this one certainly can't be missed.

10 x 30 seconds.

(sure, not a great image, but that's not the point, the point is what is visible for 30 seconds worth)

I reckon its a great pic theres plenty of detail in there...cheers Kev.

Geez... sure is a lot of detail for such a short image!

I must give the Tarantula a go sometime ....

Nice details. Short exposures work wonders on bright targets. I feel this image is worth adding some RGB.

That would be nice, it hadn't occured to me actually. However with the weather the way it is here in Perth lately, I think RGB data won't make it on to the limited schedule of astro photography

Roger,

Looks like a lot of detail and an impressive image scale but 10*30s is 300s really not 30 isn't it.

I assume that was the 12" scope as well and you do not mention the camera used , unmodded DSLR = impressive, high sensitivity, cooled, dedicated astro CDD = less so.

Still I get the gist, it IS amazing what 30s can get these days.

Sort of, I know what you're getting at, but... no matter how many 30 second exposures you do, you're still only going to get detail at the magnitude which your camera reaches in 1 x 30 sec, just you're going to get better SNR on that data. So... my point is, 30 sec (1 or 50) with 2070 I was surprised what "faint" strands of nebulosity are visible.

Yeah, I didn't bother with the details: the 12" with ST7. So yeah, a sensitive combination but still, I was surprised

Yeap
