RichLD Posted September 2, 2018 Share Posted September 2, 2018 I know, I must have imaged this half a dozen times already, however this is my first NB DSO capture in over a year so thought I'd post it anyway. I've held the stars back quite a lot on this version and I quite like the emphasis it puts on the nebula. Taken with my dual rig - 2 x Nikkor ED180 @ around f/3.46 (52mm aperture with step down rings), QHY9 10 x 900s, QHY163 15 x 600s, 7nm Baader HA. Darks, flats and bias applied, QHY9 subs resized in Registar to match QHY163, processed in PI (Linear Fit integration) and finished using a combination of Straton for a starless layer and PS. Ahh, that feels better! I really miss my AP ? 8 Link to comment Share on other sites More sharing options...
Demonperformer Posted September 2, 2018 Share Posted September 2, 2018 (edited) Very nice. I really like this target in just Ha. And it's nice to see the entire nebula. Edited September 2, 2018 by Demonperformer 1 Link to comment Share on other sites More sharing options...

lux eterna Posted September 3, 2018 Share Posted September 3, 2018 A very nice and clean portrait of the trunk. Just the right balance of stars / starless, it works great. I often use Straton (and also Registar) myself, but for me it usually leaves a lot of cleaning up for me to do in PS. Ragnar Link to comment Share on other sites More sharing options...

Thank you DP, I don't tend to go narrower than 2.0° x 1.5° these days, generally sticking to around 6.0° x 4.5° as shown in this image. I like the relative ease of widefield AP and the context it gives ? 1 minute ago, lux eterna said: A very nice and clean portrait of the trunk.

Ragnar Thank you Ragnar - yes, I find Straton to be quite hit and miss myself (it definitely needs very good SNR), however when it works well it's unbeatable. I just noticed that I didn't do a final crop of my image - there are stacking artefacts at the bottom of the rame, DOH! ? Link to comment Share on other sites More sharing options...
