  1. Thanks for the report. I am not actually getting a MESU but my next mount will have SiTech control.....hence my interest. Best of luck as you continue to explore and use the new mount. Clear skies too
  2. For those that prefer less green.....
  3. Just a closer look in at SH2-284 (Hubble Palette)
  4. Hi Stuart.....I did a quick run at it this afternoon. There were some artifacts in the OIII, but I ploughed on and just ignored them - really only looking to see what the data gave me......not trying to make an APOD For a start you can see that we have completely different approaches to NB data.....there is no comparison on the final colours. However there is underlying detail that is there to be brought out no matter which way one goes about it. I mixed Ha, SII & OIII to make a Lum layer which then went back in to make a final LSHO. The second image is HaSHO - again a quick effort just to look at possibilities and not a fully finished image. I am sorry if my colours hurt your eyes....it is just the way I work with NB data. (Obviously I cropped the final images also - again for me, that is how I would finish them). Regards.
  5. it is hard to call a halt on processing something because it is "not very interesting". I have found the same at time....head off on a long data acquisition run only to be a little underwhelmed by what the final image is throwing up. Still.....worth finishing this one I think.....just a general search on the internet throws up some OK images. Thanks for putting the stacked images up. I have a bad weather week in front of me....don't mind if I do play with the data....and I will let you know how it turns out in due course.
  6. Especially for those of us who prefer "traditional" NB colouring (closer to Hubble palette than the last post). Like Rodd - I would be interested in any remarks comparing the two approaches. See both together at http://www.kinchastro.com/sh2-284.html
  7. ....as long as the nights stay clear
  8. Thanks for that - and good luck with hunting it down. Good thing I am retired - I spent 8 hours almost just playing with the processing today. At least I got a picture at the end of it all....I was not too sure for a while though.
  9. I found it quite difficult to get a half decent image out of this....and it is 20 hours in total! The signal is reasonable (but not great) in Ha but weak in OIII and even weaker in SII. (In fact I can hardly see 6 hours of SII on my screen). My intention was to try for an SHO image but did not like what I was getting. Then opted for HOO, but again was not too happy. This is actually a combination of the two. (Ha: 8 hours and 6 hours each OIII & SII). Not often imaged - there are very few examples to check against on the net - so hope you enjoy looking in on SH2-284. (I will have higher res up on my web site later tonight - Jan 17th).
  10. To be honest....spending most of my time working with NB data - I could not say which is more "correct"...... but on my monitor, the top one is more natural....if I can put it that way. NB.....working on images for a year or more can be dangerous for your mental health!
  11. Of the two.....I prefer the top image.
  12. For me the 0.73x worked very well - I really liked it (Still do but have not used it on the 106ED for a while now). The extender also worked OK but the conditions really need to be excellent for the extender....as does your tracking. Either one requires that the back focus is spot on - the 3rd diagram on this page might help: http://www.kinchastro.com/connection-diagrams---hardware.html The other thing to check is how much your imaging changes - the field of view and the ArcSec/Pix. (CCDCalc is good for this). If you like what you see in that regard - then go for it......I think it is a good piece of kit that will give variation in your final images.
  13. This is just two nights of data capture - not nearly enough for this object.....but I have already moved on. Total 12.5 hours (ha 5, OIII 4 & SII 3.5 hours). Full info on my web site....if interested. Since it is not imaged very often....I guess a little is better than none at all. (I do hope I can come back and add to this....but it won't be anytime soon). It is quite noisy - but I will blame the moon for that
  14. Thanks guys.....yes, 1.9 AS/Pix works a treat for me as the seeing is most likely only rarely any better than that and it makes it very forgiving for the guiding. I am usually guiding at 0.6 AS/Pix give or take but at times it can wander over 1 when the relative humidity is somewhat bad......but it never affects the final image.. This is the same image data as my previous post (Rosette) which shows the full FoV (almost). It is a total of 16 hours: 5 each Ha & OIII with 6 hours SII.
