Great capture Tel. Especially of the merging storms. You could get the Nobel prize for Planetary Storm Mergification for that.





Er, um, OK, maybe not. But still a good pic.

Hey guys, once again great stuff. I've been busy with school, but got around to processing this one. It's different from other stuff I've done so I like it.

~1h of 30s exposures with a Canon 70-200mm L @ 200 F4 on a T2i @ iso 800. It was piggybacked on the clubs Paramount ME and guided. I was shooting into the light dome of Victoria (300,000 population) so there was a severe gradient, but pixinsight solved it quite well. I calibrated with ~ 50 darks, bias and flats, but it was still very noisy due to the light pollution. As you can (hopefully) tell I captured the Trifid and Lagoon nebulas. I hope to process the lagoon data I simultaneously gathered on the Tv 127is soon.

Sorry it's so small - I had to re-size with paint to get it in under the limit, and well... it took a fair bit of shrinking!

That looks really crummy. I'll do a better compression on my laptop in the morning. Apparently paint's jpeg conversion is lacking. Also I forgot to mention this is heavily cropped - maybe 1/4 of the original frame left after I tossed out areas corrupted by light pollution etc.

I wieh I could capture such a "crummy" picture. A little noisy but still lots of detail. Thanks for posting

James

That's an awesome capture. Did you use a tripod collar or did the F/4 held on by itself to the camera? I wanted to try mine ( I have the same L version ) but unsure if it would hold.

Here is a better version. I haven't changed or re-processed the picture, just converted it using iphoto rather than paint. Thanks for the comments guys.

Maverick, I didn't use a collar - I don't really have the exorbitant amount of money to buy one of Canon, and am unsure if I would trust a knockoff to support that lens + camera at the weird angles and equatorial mount throws up. I'll look into it, as that is a very good suggestion to knock off some of the vibration I've been getting. The good part is I only have a rebel, so the camera body wouldn't be overly weighty for such a ring to support.

Cheers,
Dan

Thanks so it would mean I could use this lens with the T2i body piggybacked on C6? For some reason I was really worried the weight would sort of weigh it down.

I was using a very, and I mean very solid camera mount. If you have one, then I'd say go for it, but I don't want to be liable!!! I'll look into some rings for us. Would make life easier.

Don't worry Uggbits, I wouldn't hold you responsible. I don't have any access to rings except for the Celestron piggyback bracket which my friend had bought and that which is fixed to my C6. I will give it a brief try tomorrow and see if the whole set up works. Maybe try 30 secs on M31.

Ugg`s, lovely image ,maybe its just me, but for some reason i very much like the first image rather than the second, to me it looks that little more sharper, while the second looks smoother, either way, great wide field

best regards,

Tom.

HI Ugg's,

Congrats on a fine image.

I two like the first one the best. it's much clearer, to my eyes, than the second one.

Thanks for posting.

Regards. Peter.

That's another +1 for the first image Ugg.

Nice cap. It just 'pops' for me.

Hi Dan,

Very nice wide field, in either image. Re: the cmment that it might be a bit noisy, I can't tell what is noise and what is that really dense star field. Either way, I like it!

Dan, this is a very nice looking picture. I understand your frustration with the limitations for sharing. Sometimes I found you can get around the ancient and thoroughly obsolete forum capabilities by posting on external site and then embedding the image with tags. I am myself looking into trying regular lenses as opposed to scopes to capture what you have done here.

I also agree that the first image looks sharper and poppier than the second one.

Thank you.

"Poppier". Hmmm... I think that might be one of those astro "technical" terms, right Alex? Good to see you are having more time to join us now and then. Waiting for more Alex images.

A very nice wide angle image Uggs, combining the Trifid and Lagoon nebulae.

I only wish they were targets I could attempt, but from my backyard's fixed observing position, they are too low in my night sky.

I, like some of the other guys here, prefer the first picture although I find both, if you'll forgive me, a little washed out ?

Just for effect therefore, I took the first image and ran it through P/Shop using Auto Levels, Auto Contrast and Auto Colour. I then tweaked the Saturation a little more, made a High Pass sharpening and then finally manipulated Curves a little. (See attached).

I think it now has a little more depth to it but, as we all know, "Beauty is in the eye of the beholder" !

Best regards,
Tel

Nice work Tel, you brought out the colours with a striking background.

Tel you are a P/S virtuoso ! Nice colors and black background. You should be teaching a tutorial.

I liked the original but that is amazing!
