1. set up(there was a dent in the adapter removed from filter wheel by force(vicegrips and hammer)
- kept focus as 1913.6
2. Used Vega for pointing and took flats in all filters
2. slew to Saturn
3. slew to Uranus
4. Slew to GD391 fig 15 in paper,make sure DFM uses J2000 epoch - gain:150 actual:4.4, Skybrightness:17.74, integration time 1.2s for filter V (we can see a 15 magnitude star GD391 D !!!)
- Saved as GD391_tr011_agon.fits (source name explained tr011 means tracking rate is 15.011, agon means autoguiding on)
- PHD 2 is getting 11-13 for the FWHM - gain:150 actual:4.4,skybrightness 1.84 integration time 11.6s for filter U
- Saved as GD391_tr011_agon.fits
- gain:150 actual:4.44,skybrightness 14.26 integration time 1.5s for filter B
- Saved as GD391_tr011_agon.fits
- gain:150 actual:4.44,skybrightness 20.2 integration time 1.1s for filter R
- Saved as GD391_tr011_agon.fits
- gain:150 actual:4.44,skybrightness 4.62 integration time 4.6s for filter I
- Saved as GD391_tr011_agon.fits
5. Slew to Vega
6. Slew to Mirach to focus the finder DON'T TOUCH THE WHEEL
7. Slew to Darth Vader's starfighter
8.Slew to Uranus,Saturn,Neptune,Jupiter(take images in BVR 5ms)
9. Attempted a couple nebula and Galaxies most bad
10. take NGC 891 frames in BVR for 3 minutes each and then 6 frames for 30s in BVR
11. Slew to NGC 2276 and Take 3 minute frames in BVRI
12. Slew to Zenith and take darks 3min,30s,11.6s,4.6s,1.5s,1.2s,1.1s,5ms 13. shut down procedure leave
