  SNR 3C4002,PN G053.1-02.1 (Sagitta).jpg - Supernova Remnant 3C400.2 , PN G053.1-02.1 (Sagitta) * June-July 2014 * ASA N12 astrograph (f/3.6,1078mm) * ASA DDM85 mount * FLI ML8300 at -25ºC * LRGB Optec filter set * Baader Ha 7nm filter * LHaRGB ( invested time 33,5 hours) * Unguided * Very probably, this is the very first amateur image of this Supernova Remnant.Thanks to Mr. Sakib Rasool for the information.It was very complicated  to image, as it´s extremely  weak and inmersed in a very rich star field,( which difficult, even more) it´s vision.At the bottom edge of the image, a little Planetary nebula, can be seen.The extended Galactic radio source 3C 400.2,was first identificated as a Supernova Remnant by Holden & Caswell (1969).Its radio properties are typical of the majority of SNR:it has a thick shell morphology,with a diameter of 30´, showing an irregular shell struture.Optical emission associated with 3C400.2 was first reported by van den Bergh,Marscher&Terzian (1973), who noted very faint filaments amidst the crowded stellar field (Palomar 5m  telescope).A few knots appear along with more extended diffuse filaments,all in the southeastern portion of the radio shell.The distance to 3C400.2 is poorly known..estimated in d= 6 kpc.Despite the large uncertainty, 3C400.2 is clearly a large,evolved remnant.The most striking feature of 3C400.2 is its dramatically different morphology in optical,radio and X-ray regimes.Credits: The Astrophysical Journal,405:608-613,1993 March 10P.Frank Winkler, Todd M.Olinger,Scott A.
