M 94 taken with two telescopes with a 2-year interval.
<br>Shooting this year on a 300/1200 Orion UK and a SvBony SV705C camera with an Antlia Triband RGB Ultra filter, I couldn't bring out the ring around the galaxy, the reason is very poor sky, although the center worked out not bad, although perhaps the filter is also a reason.
<br>And in 23, shooting it on a SW Quattro 8S telescope and a ToupTek IMX571 camera, the ring was there.
<br>So I decided to combine these two shootings and see what comes out in the end.
