morimarty Posted September 20, 2011 Share Posted September 20, 2011 HiJust finished my summer target m57@f/10. As all you imagers will knowI had to dump gig loads of data in the recycle bin due to guiding issues @ 2800f/l.Anyway here is the best of what I managed to capture.scope- celestron c11mount-neq6camera- canon 450dfilter-astronomik cls ccd clipcapture software-backyard eosguiding-phd40 subs 250secs @ iso800 (2hrs 46mins)40 darks " " "no flats/biasstacked-dssprocessed-ps7 Link to comment Share on other sites More sharing options...
Keiran Posted September 20, 2011 Share Posted September 20, 2011 Thats a very nice ring yopu have there. That is some time you put in to that 5.5hours... And it paid off. Is this a crop? Link to comment Share on other sites More sharing options...

RobH Posted September 20, 2011 Share Posted September 20, 2011 Lovely detail in the nebula.It does look like you've clipped the black though....go a little easier on the blackpoint and you should begin to see some fainter nebulousity around the edge.Anyway, an image to be proud of CheersRob Link to comment Share on other sites More sharing options...
ollypenrice Posted September 21, 2011 Share Posted September 21, 2011 I think Rob's right but, blimey, we don't see many Rings at nearly three metres! And this is quite something.There have been several threads on how long a FL is viable on an EQ6 and I think you are defining a clear upper limit here! You were very brave to try this. What percentage do you reckon you lost?Olly Link to comment Share on other sites More sharing options...
morimarty Posted September 21, 2011 Author Share Posted September 21, 2011 HIThanks to all for your comments they are very much appreciated with this being my first posting.ROB, I have to agree with you clipping the blackpoint. funny thing is though i kind of new i was over doing it. but could not stop myself OLLY, when i first started out on this project i was guiding using an st80 piggybacked on the c11. but i could not get nice round stars. then i read an old thread on SGL (f/l on eq6) i think it was your good self saying the only way to image @ f/l 2800 would be to use an OAG. so that was the route i chose. and after a few nights practice i finally got nice round stars Link to comment Share on other sites More sharing options...
steppenwolf Posted September 21, 2011 Share Posted September 21, 2011 I can only dream of getting that close in to M57 - the other two are right about the clipping (we can also only dream about backgrounds being that black!) but this is looking like good data so well worth doing a re-process.

morimarty Posted September 23, 2011 Author Share Posted September 23, 2011 Steve,Thanks for your reply. i am going to take your advice and reprocess the image. but i think i will try to capture some more data first then add to the data i have captured so far.

There outer shells that are tantalizingly faint. Best of luck with this, it's a great project.Olly Link to comment Share on other sites More sharing options...
