Picturesque as always, the night sky above Lowell's Discovery Channel Telescope last night. Photo thanks to Dr. Joe Llama, one of our astronomers out observing on the DCT. • • • #lowellobservatory #lowell #observatory #flagstaffaz #flagstaff #arizona #discoverychanneltelescope #dct #telescope #science #space #astronomy #astrophotography
The finished product! This fresh mirror coating was achieved by putting the clean 14-ft glass in a vacuum chamber and then having vaporized aluminum fall onto it. #lowellobservatory #lowell #observatory #arizona #dct #discoverychanneltelescope #telescope #mirror #science #space #astronomy #optics #engineering
Now without its aluminum coating, the mirror's glass needs to be extra clean before it is put in the re-aliminization chamber. . . . #lowellobservatory #lowell #observatory #arizona #dct #discoverychanneltelescope #telescope #science #space #astronomy #engineering
The DCT's 4.3-m (about 14 ft) mirror was lifted out of the M1 cell this afternoon. Next the mirror needs to be carefully cleaned in preparation for re-aluminization. #lowellobservatory #lowell #observatory #arizona #dct #discoverychanneltelescope #telescope #mirror #science #space #astronomy #engineering
And touchdown! . . . #lowellobservatory #lowell #observatory #arizona #dct #telescope #discoverychanneltelescope #science #space #astronomy #engineering

M1 is out! Now to lower it down and lay it flat. #lowellobservatory #lowell #observatory #arizona #dct #telescope #discoverychanneltelescope #science #space #astronomy #engineering
A DCT engineer removes counterweights on Lowell's DCT. This is just the beginning of the process to access the DCT's mirror for re-aluminization. #lowellobservatory #lowell #observatory #dct #telescope #happyjack #arizona #science #space #astronomy #engineering #discoverychanneltelescope
