My best ever Eta Carina

[tornado33]

Hi
With excellent conditions last night I went for Eta Carina, 45 mins total
3x15mins iso 400, Idas uv/ir and Baader uhc-s filters, MPCC, Modded 350D. 10 inch f5.6 newtonian off axis hand guided.

Just had a go at masking to preserve inner detail.

Wow Scott - both images are stunning. The full size links are fantastic. Superb technique in guiding, capturing and processing.

Cheers

Exceptional Scott. :clap:

Yes Scotty that is indeed a very nice image!

Since Paul has now seen the life changing revelation of autoguiding, you must now be the last man standing who still guides by hand? Seeing Pauls previous setup took me back over 20 years. I had the same Samson mount (mine was black), same drive corrector even the same dodgy Astro Optical plastic RA drive but with an 8" F7 Newt. It was a nightmare to image with and I cringed when I saw Pauls old setup as it brought back all those feelings of frustration :lol: His new setup is pretty schmik though.

Good to be in Newcastle BTW, must get together sometime :thumbsup:

Thanks all
Yes, Mike id love a rig like Pauls (or yours). My scope has a Sutching mirror, with a pristine overcoated coating my Chi Qin optics, Id love to have that in an autoguided rig but not until I win lotto hehehe.

:) Impressive ....well deserved after 45min of tortuous {I assume anywhy} hand guiding

Hi Scott,
A top notch image!!!....:thumbsup: like all of yours..
Your`e not alone in hand guiding there...scott, but autoguiding is on my list after I get argo-navis.......
Cheers Gary

[skeltz]

So many pictures here are worth mentioning,yours thouhg is extremely worthy...rob

Hi Scott,
Gos to show what longer exposures can do, very good nebulosity detail, not normally seen in shorter exposures, I prefer the masked picture myself, but both have their qualities, very good guiding and pinpoint stars for a long exposure, this ones hard to beat.

Thanks all. Yes Guiding is the challenge,cant really relax or look away for very long to prevent drift. That said, the old Sampson mount tracks surprisingly well, it does have periodic error but its a slow type of side to side error that can be corrected for. I imagine if I had a motorised Dec and the drive corrector was modified to accept autoguiding, it might autoguide quite well.

That's an excellent Eta shot. :thumbsup:

Wow, now that is just stunning, well done Scott.

Cheers Leon

[davidpretorius]

speechless! one of the best astro images i have seen!

[danielsun]

WOW!!!! That's absolutely fantastic!!!
:eyepop:
It wont really matter if they decommission the Hubble, NASA can just use your images.

[atalas]

Nice work Scott .

As D.P. said

Hi Scott,
Very good definition and colour, your guiding is spot on, the smallest stars are round and well defined, difficult to improve on this one.

Make that 2!
I still guide by hand, mind you i dont have a digital SLR or CCD camera either....its quite a stretch to guide on a star for an hour or so....but the results are worth it! :)

[tornado33]

Yes indeed :) I remember in the old days of film, some ppl using Hypered Tech pan film often guided by hand 60 to 120 minutes, in a SINGLE exposure! What really impresses me about that is the field rotation and flexure had to be so well controlled for such long single images.

Top stuff Scott !!
I like the second masked version the best.
I hate seeing things over saturated when simple masking can help reduce this.

Cheers
