Andromeda with Triangulum and the Intrastellar IFN

V. II of this image re-processed for better color

 

Here is a late processing of a widefield target from earlier this fall. This field contains two major galaxies The Andromeda Galaxy(M31) and Triangulum galaxy (M33).

 

The IFN "integrated flux nebula" is a very faint dust cloud which reflects light emitted by our milky way. IFM and ISM, interstellar medium, can be spotted sweeping across vast areas of our skies. There are several surveys which have mapped out the IFN whihc can be very helpful for identifying faint structures. It is very difficult to discern between gradients and ifn when processing structures this faint. I was able to pull a strong luminance image from the green channel and bring out the faint nebulosity by blending with the original image.

 

The light frames listed below are referring to how many exposures of the deep sky object were taken and also the length of each exposure which are used for stacking in the program pixinisght, the dark, flat, and bias frames are calibration frames which help to eliminate different types of noise, vignetting, and dust on the sensor. It requires many hours of work to produce just one astrophotography image.

 

 

This image is 70 x 90s subs at iso 1600 using a full spectrum T2i and astronomik uv/ir cut clip filter. Lens was a pentax-m 50mm F1.7 stopped to F4
