1920 - prepped dome and closed hatch
1930 - auto dome is not working even after setting the dome position as per telescope azimuth and it is observed that in that dome manual panel in the accessories is turned on (checked it from the dome and control room tour ppt and turned it off) still the dome is still not following the telescope
1930 - connected ascom, dfmtcs and sky6
1957 - capture the darks cal [ filter :U ,Int time:12,Gain:0,Capture Area 1400*350(218,1188)]
2008 - capture the LED cal [ filter :G ,Int time:12,Gain:50,Capture Area 1400*350(218,1188)]
2220 - It is not pointing correctly, When we tried to point to a target it is showing the wrong star. Tried to change the telescope position in the DFM as per what we are seeing in the screen and then slewed it to the target star(deneb) then still it is showing way off to the target. Also tried adding the RA&Dec values in the set slew position but it is not taking us to the target. Every time after slewing, we are cross checking in the astrometry.net to verify that we are watching the correct star.
2222 - Starting pointing it to arcturus, It was way off (confirmed through astrometry.net). Took feed back on what was on the screen on astrometry.net and moved the telescope accordingly manually. plugged in the values into the telescope position into DFMTCS and then slewed to arcturus. double checked with astrometry.net and boom jackpot. Fixed!!!
2252 - Slewed to Iota her
2314 - Slewed to Tau her
2337 - Slewed to HD 154445, changed the exposure to 100ms, it was dim.
0006 - Slewed to Beta Cep
0029 - slewed to Iota her
0057 - slewed to Tau her
0122 - slewed to Iota her
0137 - Light cloud cover rolled in.
0142 - slewed to Tau her
0204 - slew to phi cas
0208 - slewed to tau her to initialize for pointing using Ra/Dec Cords from stellarium
0216 - decided to give up on phi cas after re-initializing and not finding it.
0217 - slewed to Alpha Lac
0224 - slewed back to tau her and used next object position
0225 - slewed to alpha lac and pointing is better now
0227 - cloud cover is a bit better.
0245 - slewed to Iota her
0303 - slewed to gamma peg
0324 - slewed to Zeta Cas
0343 - slewed to gamma peg
0402 - slewed to alpha lac
0425 - slewed to Zeta Cas
0445 - slewed to gamma peg
0501 - light clouds have rolled in.
0502 - stopped using Phd2 to guide
0507 - slewed to alpha lac
0525 - slewed to zeta cas.
0543 - slewed to gamma peg.
0604 - Starting shutdown
0611 - when doing dome shutdown found blue ladder not behind safety line and below telescope.

Auto dome is not working
