Popular Post Greg M Posted June 13, 2021 Popular Post Share Posted June 13, 2021 (edited) I captured this over two evenings. I hoped for even more data but both evenings the winds picked up and scrapped the imaging. 21h 39m 00s +57° 29′ 24.0″ IC1396 is a concentration of ionized gas in the constellation Cepheus. The Elephant Trunk itself is IC1396A and is the vertical tenuous stream of gas coming from the bottom of the frame up towards the center. The bright red star in the upper right of the frame is Mu Cephei, also known as Hershel's Garnet Star. It is a red giant and thought to be one of the largest known stars with a radius of 1,000 times our sun. If it replaced our sun it would reach between the orbit of Jupiter and Saturn.

Maybe the background needs adjusting a little to remove the magenta, but overall an excellent image. Did you use the Lum data on the stars, or for the nebula? If it is for the nebula, using the Ha as a lum will probably give better results. 1 Quote Link to comment Share on other sites More sharing options...

I would like to get more data and re-stack before I bother any further. I'm not a real stickler when it comes to processing. I don't use P.I., I use A.P.P. with the default settings and just let it go. I am not one of those guys that will spend hours on processing. But I'll keep your advice in mind if I'm able to grab more data. Quote Link to comment Share on other sites More sharing options...

Same here, because i am just now starting to do DSO with good scopes, i got my 90mm Triplet this year 2 months ago after i ordered it as an alternative last year, and last year i bought 6" F/4 Newt, but with all that i am still not good at processing and i don't think i have to spend hours while my data isn't good enough yet, and i also feel like my life isn't only dedicated to astro so i gave hours for imaging and another hours for processing and i keep that forever, so i hope one day i can find a balance and make good data and processing without wasting time on both. 1 Quote Link to comment Share on other sites More sharing options...
MarkAR Posted June 18, 2021 Share Posted June 18, 2021 Superb image, love the green you've left in. The purple detracts a little but hey ho!!! 1 Quote Link to comment Share on other sites More sharing options...
