M 109 can be seen a hazy spot situated 40' SE of the star γ UMa (Phecda). The galaxy is about 7.5' x 4.5' arc minutes in angular extent, and is of visual magnitude 9.6. Only its bright central region (with the bar), can be seen visually, and appears pear-shaped in smaller telescopes. The inner halo is mottled, and surrounds an irregular bright oval core. M 109 is one of the "Theta"-like barred spirals, classified as Hubble type SBc.
This type of medium / small galaxies ( less than 20 arcmin.) represent the 99% of the galaxies up to magnitude 12 of the Northern Hemisphere. To appreciate the details with a low exposure it is necessary that they occupy most of the FOV and tha chip is very sensible to light. The combination of the SKW Quattro + IMX224 is one of the simplest and cheapest options.
SKW Quattro+ IMX224+ Risingtech software

I love that shot, this is what appeals to me. Simple, not over processed, kinda old school.

Thank you
This I always try to do, make things easy and simple.
I will not compete in a photo contest but I like to improve the result of working with simple equipment and short expositions.
