| Date: | January 18, 2005 |
| Exposure: | LRGB 46:32:32:49 : 23 x 120s L, 8 x 240s R, 8 x 240s G, 7 x 420s B |
| Processing: | CCDSoftV5 for image acquisition. MaxIm for image calibration,(10 each LRGB flats, dark subtracted and median combined, 80 bias frames median combined, 15-900s darks Sigma Reject combined), alignment, normalization, stretch, and RGB combine. 3 iterations of CCDSharp on the Lum layer. Photoshop CS for LRGB processing,final adjustment and jpg conversion. |
| Conditions: | Average |
| Scope: | C14 @ f/11 |
| Camera: | STL-1301 w/internal filter wheel |
| Comments: | This was done all unguided as I am still getting mirror drift when guiding with my external guidescope. Working on the next iteration of the mirror lock saga which might have some promise. The seeing was not very good during these exposures as is usually the case here in SC. |
