alan4908 Posted January 7, 2020 Share Posted January 7, 2020 The galaxy NGC4216 is in the Virgo Cluster about 55 million light years from Earth. It is shown in the center of the LRGB image below with two main companions NGC4206 (top) and NGC4222 (bottom). Also displayed are a few background galaxies. The inclination of NGC4216 is 89 degrees so, it is almost edge on, making the revelation of dust lanes difficult, so I was quite pleased that I managed to capture a few details. I've also inserted an annotated version which shows the location of the background galaxies (if there are any PI experts who know how to stop PI writing different annotation identifiers to the same object please let me know.....). The image represents 12.5 hours integration time and was taken with my Esprit 150. Alan LIGHTS: L:19, R:12, G:14, B:30 x 600s. DARKS:30, BIAS:100, FLATS:40 all at -20C. 20 1 Link to comment Share on other sites More sharing options...

geeklee Posted January 7, 2020 Share Posted January 7, 2020 That looks amazing. IC771 looks interesting as well with it's differing colour. Thanks for sharing. Link to comment Share on other sites More sharing options...

Thanks, yes IC771 does look interesting, I was quite surprised how blue it came out. 16 hours ago, orionoffelt said: Nice image Alan good detail. Bob Thanks Bob - I think the deconvolution on the stacked Lum data helped to bring out the detail. Alan Link to comment Share on other sites More sharing options...
han59 Posted January 8, 2020 Share Posted January 8, 2020 Very nice image. The image details of NGC4216 are amazing! There are more galaxies to see. I can't help you with the PI annotation, but here an alternative annotation by ASTAP of your jpeg file. (but I'm a little puzzled by the SDSS entries around NGC4216): Link to comment Share on other sites More sharing options...

I was quite impressed with the amount of detail revealed on NGC4216, as I mentioned above, I think this was mainly helped by a application of deconvolution on the lum data. Thanks for the information on the ASTAP program, I shall investigate further ! Alan Link to comment Share on other sites More sharing options...
