$This image combines images taken with the ST-10 CCD (Luminance and HA filters, 13x5 minute and 7x8 minute L, 8x5 minute HA) and an astro-modded Canon 6D DSLR camera (RGB via Luminance filter, 13x6 minutes), all on the Meade 16\" telescope at f/5. The red blobs are the HA emission, indicating star forming regions within M51.$

$Image of M51 through the Meade 16\" at f/6.3, taken 3/31/13. Image is composed of Red, Green, Blue, and Luminance images (R:7, G:8, B:15 seconds binned 3x3, L:7 seconds binned 2x2). Roughly 15 minutes worth of exposure for each filter. I\'ll call this a work in progress, as it\'s still early in the season for M51!$

$The best of both worlds- this images combines the wide field optical quality of the Takahashi FSQ-106 with the light gathering power of the 16\" Meade. Cropped from the full size image, the base images are the same as the previous M33 image, with 16\" images of the core aligned and seamlessly blended. Processing done in MaximDL and Photoshop, done by M. Polansky.$

$The Leo Triplet of galaxies, featuring NGC 3628 up at the top, M66 on the bottom/left, and M65 towards the right. Whole image is taken through the Takahashi FSQ-106 telescope, with images of each galaxy through the Meade LX200 16\" at f/5 composited in for extra detail. Total image exposure time is about 3 to 4 hours, in LRGB.$

$This is M51, imaged through a Meade 16\" Schmidt Cassagraine. 30x Stacked Images, 10 seconds each, through Red, Green, and Blue Filters.$

$Color Composite LRGB 40:12:12:12 min. 2x2 binned, ST-10 on 16\" @ f/6.3$
