.... Take images in 3 filters, perhaps R V U. Take at least 3 pictures to removecosmic rays and to cover the gap between chips. The Gap is 3.5 arcseconds wide so use offsets like (0,0), then (+7,+7), then (-7,-7) arcseconds. Exposure times.... it's a bit of a guess, maybe 60-120 seconds for each for the galaxies ??? I can combine the images or teach you how to do it.

Some ideas for Minicam... these are 4x4 arcminute pictures from DDS, seeing in DDS is about 3"

Galaxies ... Extra-Galactic Objects


U V R works well. 90 seconds each exposure works well. To really fix the gap we need at least 4 pointings.

Dark Nebulae ...


Probably best in narrow band filters, but B V R should do fine, Keep exposures short to minimize saturated stars, then take more exposures to build up total exposure time.

best with narrow band filters, if not available then use B V R

Globular Clusters...

Exposures: take B V I, exposure times of ~10 seconds, do 5 exposures each. Try to minimize saturating stars. NGC 5053 doesn't have that very bright central core, as seen in many globulars, it should make a great "full of stars" picture.

.... Take images in 3 filters, perhaps R V B. Take at least 3 pictures to remove cosmic rays and to cover the gap between chips. The Gap is 3.5 arcseconds wide so use offsets like (0,0), then (+7,+7), then (-7,-7) arcseconds. Take all images before switching filters. Exposure times.... it's a bit of a guess, maybe 60 seconds for each for the galaxies ??? To combine the images, I can either do it for you or tell you how to do it.
9 exposure @ 60 seconds + 40 seconds overhead/exposure = 15 minutes
