Wah! Great imaging! You can be very proud of this ISS video.
1.) Did you use a filter?
2.) Do you image at full sensor size with your ZWO ASI174MM?
3.) Did you record in SER. File or AVI File.
4.) Do you have a website?
Thanks all! I was using a finder to track the ISS. No filter has been used because I wanted to grab more light. I was using full resolution to increase the chance. The capturing software is SharpCap, it stores data as SER by default. I dont have a personal website, I usually post images in hkastroforum.net, although I havent post for quite a long time :P
