NGC1055 Galaxy - Oct 2017

This is a 10 hour exposure of the NGC1055 galaxy using a standard Canon DSLR. The image is taken with a Celestron 8" SCT at F10 (2032mm focal length).

The image consists of mostly 600s subs and approximately 2 hours of 90-150s subs, all at ISO 800.

This galaxy is located at about 60 Million Light years distance from us, and at a magnitude of 12.5 is quite a faint object to image, especially when there is a little bit of light pollution with in the par of the sky it is imaged at... Looking at the result, I probably should have used the f6.3 FR to have less over sampling and most likely capturing more light in the same amount of time, or same amount in less time... end result most probably, at worst, would have been the same if not very similar and at best there might have been a bit more detail captured since guiding at 63% of the focal length and not oversamplig the subs would not be as susceptible to seeing/star fluctuations/movement.
