Another Mr. Ed?

After seeing Doug's wonderful HH and all the repros lying around I couldn't help myself. Never got a good HH in 2 years I've been imaging and I can't wait to see it come back to give it a proper go. I recently got a licence of registar which is just great for registration. I have sooo many subs on the HH I though I'd throw everything I got in, the good and the bad and see what comes out of it. So this is my heavily cropped 1:1 HH + flame nebula. I guess all the frames being rotated, offset and what not this is the "intersection" of all the data

So it's smooth alright but cropped. I can't say exactly but there's about 9h of Ha, and a good 5h of RGB so it's a HaRGB blend. That was all taken over a period of 2 years with the QHY8 on my 5" newt at prime focus.

There's a high res version at: http://www.multiweb.com.au/astro/HH_f.jpg

Nice Marc, it is a shame you had to crop it so heavily. This target takes a lot of exposure to bring out it's best. I left my rig snapping away 20 minute exposures and went to bed to try and get the best I could and to be honest the skies at Snake Valley were fantastic, Mag 6 and 7 stars jumped out to the naked eye even with the sky glow from melbourne and ballarat. What I would do to live in an area with skies like this. I hope to add some Ha to my copy in the near future.

Give this target a new go with big long subs. It's worth the effort for sure.

Isn't Registar something else for registration of images. I bought a copy a while back and was very happy once I worked it all out.

Nice one.

Loads of detail Marc. Would of been better if it wasn't cropped though. I am not sure that you could't get the same result with say a two night sitting session? I look forward to the complete uncropped version. Nonethless fantastic detail

OOoooooh Ahhhhh !! Thats a lot of subs.

That's a good image Marc

. Yes, shame about the heavy cropping and the slightly mismatched registration (double diff spikes), but the result is smooth, detailed and quite pleasing.

Cheers, Marcus

Thanks Doug.

I'm going to do a serious coverage of it this summer and try to get a good RGB of it for a change. The only decent shot I have is all Ha from my backyard and still not much to look at. Too noisy. Registar is awesome at registering. Not sure about the blending/stacking functions though. Seem to get a lot of gradients from subs to subs. Not sure if it's normalisation problems but I can seem to blend anything nicely. I just register and save to finish off in CCDStack.

Thanks Paul. It would be certainly

But you should have seen the subs I made this out of. It's like a patchwork. This is the biggest common area I could get.

Far too many David.

Thanks Marcus - Yeah it turned out smooth which I liked. The double diff spikes are in the subs, not a registration problem. My secondary at the time was slightly rotated so I had 8 spikes instead of 4. I could get rid of those diffraction lines too that go across but I didn't bother as I'll have to re-shoot the whole thing anyway. Better next time.

Looks great mate.. I have got to get me a registar licence

F/6? what is F/6??

yea man.. Im hanging out to see 4hrs of 5min subs of the horse through the C11 @ F/1.8!! its gonna be crazy... I got $10 says that if you shoot 40mins of 1min subs you'll decimate my 8.5hr image..

Bassnut (Fred) · #10 28-10-2009, 08:42 PM

Yes, very nice Marc, but yr missing the "rain" effect on the HH often seen. Similar exposure times on the fastar would bring them out.

That's $20.00

Thanks Fred, yes it is more evident in the Ha lum but most of it is cropped

Will do a better job of it this year round now I know a few more tricks.
