DG181,DG182,LDN 1175,LDN 1184 (Cepehus) * September-October 2014 * ASA N12 astrograph (f/3.6, 1078mm) * ASA DDM 85 mount * FLI ML 8300 at -25ºC * Optec LRGB filter set * L:750m R:310m G:300m B:330m * Unguided * DG 181, DG 182 (Dorschner+Gurtler catalogue) are two tiny blue reflection nebulas located between the LDN´s 1175 and 1184, into the cloud TGU640 of Cepheus constellation..Rarely imaged (or never imaged ? ) the area also contains IR objects such as IRAS 22148+6033,IRAS 22151+6040,IRAS 22158+6041 and X-Ray objects as 1RXS J221635.3+604813 . The whole area is inmersed into a mix of dust and reflections , making it a difficult task for astrophotographers. A lot of hours were invested in order to present it with some detail and colour. Many thanks to Sakib Rasool for pointing me these targets. | ![]() |
