Padraic M Posted July 24, 2021 Share Posted July 24, 2021 One area of space includes Messier 57 Cassiopeia Salt and Pepper Nebula; Caldwell 11 Bubble Nebula; NGC7538 Northern Lagoon Nebula; and by special request also contains the supernova Nova Cassiopeia 2021, back again to magnitude 6.96. Captured on 23rd July 2021 in HaRGB. The supernova is the red star in the lower centre. Do supernovas radiate energy in the Hydrogen-alpha band? Image comprises: 9x 300s each of red, green, blue Baader 6x 300s Baader 3.5nm Ha Esprit 80, ASI1600mm Pro, HEQ5 Pro Starwave 50mm guidscope, ASI290mm Mini AstroPixelProcessor, PHD2, Nina, Gimp. 8 Quote Link to comment Share on other sites More sharing options...

Another panel on top of this one would certainly capture the Lobster Claw, and NGC 7510. 1 Quote Link to comment Share on other sites More sharing options...
