ribuck Posted April 30, 2021 Share Posted April 30, 2021 (edited) Hi all, new to the site and new to the world of imaging with Newtonian's. I've done some imaging in the past with a 102mm doublet, but i recently purchased a 10" Quattro and boy was it a steep learning curve coming from a small refractor. So here is my 1st attempt at imaging with a Newt, and it still needs a lot more data to bring our the detail in the arms. Masked stretch in pixinsight messed up the cores of the bright stars, so i still have that to fix, but it's a start and i'm fairly happy with it as a 1st attempt at imaging with a newt.

ribuck Posted April 30, 2021 Author Share Posted April 30, 2021 Thanks all, i'm not completely happy with it yet, but it's a start. hopefully i can capture a bit more data to bring out more details in the arms before the season completely runs out @peter shah Many thanks for kind comment. I have seen some of your stunning work on UKAI - Would love to see your processing workflow sometime. Cheer, Rich. 1 1 Quote Link to comment Share on other sites More sharing options...

Very nice image, great detail too. To avoid the blown out stars, try doing a partial stretch with ArcsinhStretch, then finish the stretch with HistogramTransformation. If the stars start to blow, increase the high range in HistogramTransformation to 1.1, this is also a good trick to use when increasing saturation etc in curves. Try keeping the white point at 0.9 or thereabouts. 2 Quote Link to comment Share on other sites More sharing options...
Vicki Posted April 30, 2021 Share Posted April 30, 2021 I think this is so pretty, some really lovely detail, well done. I miss imaging with my 5" newt just for the nice fov. 1 Quote Link to comment Share on other sites More sharing options...

Thank you all, for the kind comments. it still needs a lot of work and tweaking, but at least it's showing that the 10" Quattro has a lot more resolving power than the 102mm frac under the right conditions. In terms of the issues with the cores being blown out, after a lot of testing tonight, i've traced it back to an issue with my calibration, so just need to have fiddle with that to see if i can improve things. 1 Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted May 2, 2021 Share Posted May 2, 2021 It looks good for a first time out with a new scope. Quote Link to comment Share on other sites More sharing options...
MarkAR Posted May 3, 2021 Share Posted May 3, 2021 A great start. Looks quite pink on my screen, would that be Ha ? 1 Quote Link to comment Share on other sites More sharing options...
ribuck Posted May 3, 2021 Author Share Posted May 3, 2021 No, i've not added any Ha to it yet. I need to do more work to adjust the colours - just need to sort the saturated stars first, as you cant apply colour correctly to saturated stars. 1 Quote Link to comment Share on other sites More sharing options...
