Finally had couple clear days and was able to test filters. Result SHO image of NGC7000 North America Nebula, my favorite object aka measurement of my progress with #astrophotography
Here are results of previous years. Unrecognizable image with 50mm when I just started, 135mm last year with Canon camera. This year image at the beginning of this thread with ZWO533MC and 135mm. Looking forward to next year.
