Popular Post Alec Posted October 20, 2020 Popular Post Share Posted October 20, 2020 Took these he other week trying out the new autofocus routine on the asiiar, the version 1.5 is a real joy to use. 40 x 120 second lights, 15 darks at unity gain and zero deg temp. Processed in Pixinsight for the first time just using :- Background extraction, Color Calibration, Histogram transformation and Curves transformation.

Bottletopburly Posted October 21, 2020 Share Posted October 21, 2020 Nice work Alec I’m assuming you have a duo filter by the star colour Link to comment Share on other sites More sharing options...
Clive Posted October 21, 2020 Share Posted October 21, 2020 Nice image, I'm not used to seeing it that way up 😊. I'm intrigued as to what is causing the dual star diffraction spikes, are the opposing arms of secondary holder offset from each other? Link to comment Share on other sites More sharing options...

Bottletopburly Posted October 21, 2020 Share Posted October 21, 2020 I’d black those nuts though Alec you would think they would have covered those Link to comment Share on other sites More sharing options...
Clive Posted October 21, 2020 Share Posted October 21, 2020 Well they certainly appear to be diametrically opposite but looking at what appears to be reflections off the vanes in that image (as well as the nuts) they appear to be 'shiney' so I wonder it it could be due to that? But don't get me wrong, it's a great image that I would love to be able to obtain; it was purely an observation of something that I haven't seen before. (Many years ago when I built my 10" newt, I designed 3 vane secondary support thinking I would just get 3 diffraction spikes and obviously ended with up with 6, but these days when using a stopped down camera lens I get dozens!)

No problem, it’s all new to me only ever used refractors. Out comes the air fix mat black paint 👍 Clive and BAZ 1 1 Link to comment Share on other sites More sharing options...

Looks complex Chris, so i processed it by just by following a Youtube tutorial. Hopefully at some stage i will be able to take the OSC data and split the channels, and process it to the hubble palette, but that's way beyond me atm.

Chris P. Posted October 22, 2020 Share Posted October 22, 2020 @Alec it’s easier than you might think - and there is a trick or 2 with dual narrowband data to really make your images pop. Just give us a shout - Happy to share Link to comment Share on other sites More sharing options...
