VdB14, VdB15 eta Sh2-202 nebulosak

VdB14, VdB15 and Sh2-202

 

 

Sh2-202 eskuin aldean ikus daiteken distira ahuleko nebulosa handia da, banda-pase zabaleko LRGB iragazkietan ez dauka informazio gehiegirik baina banda-pase hertsiko Ha iragazkian dauka informazio ia dena. Honek irudiaren prozesamendua zailtzen du irudi kolore zehatzak lortzeko garaian iragazkien informazioa batzean. VdB14 eta VdB15 igorpen-nebulosa urdinak errazagoak dira...

Very large and faint nebula, Sh2-202, there is not much data on nebula in broadband LRGB filters but does well in narrowband Ha filter. Makes it great challege into processing for accurate fullspectrum images after data merge. This time used math in Pixelmath for LHaRGB merging. Blue emission nebulae Vdb14 and Vdb15 also seen in image are much easier...
