Notes | |||
During several of these exposures, clouds moved through the field. All images suffered from trailing in RA. After film processing I found the screws holding the focuser to the guide scope were loose. I fixed that, I'm also going to support the ST-4 cable differently so it doesn't pull down on the guide scope. Looks like I can expose longer than 30 minutes on E200 from this site, maybe 45 minutes. E200 pushed +1. |
