This is a composite of images taken between 2009 and October 12, 2015. I think I’ve finally gotten it to the point where I’m finally satisfied with it.
One of the finest globulars clusters visible in the northern hemisphere, Messier 15 According to Wikipedia is one of the most densely packed in the Milky Way.
Image data:
C8 @ F7.5 with Starizona reducer/corrector. QSI583wsg 64 x 30 seconds binned 2x2
C11 Luminance taken 08-17-2012 Cherry Springs State Park. C11 QSI583wsg Starizona Reducer 4 @ 5minutes 12 @ 2 minutes and 26 @ 1 minute (still blew out the core with 1 minute subs)
Color layer RGB taken from a session on 8/18/09 from Pulpit Rock. Celestron C8, QSI583, Meade 0.63 focal reducer (too much distortion with this reducer).
Images acquired in Astroart. Stacked and calibration frames applied in Deep Sky Stacker. Stacks aligned and registered in Registar. Processed in Adobe Photoshop.

M22 in globular cluster in Sagittarius. It is one of the nearest and brightest clusters. Certainly one of my favorite visual objects. I had imaged this several years ago with my FLT-110 and was quite satisfied with the results. That was until a fellow LVAAS member sent me an image taken with a 12” Ritchey Chretien. Unfortunately for star clusters aperture rules, hence the need to drag a larger beast with me.

Taken at Cherry Springs State Park July 16-17th, 2015. Celestron CGE1100 with a Starizona F7.5 reducer/corrector (2100 mm effective focal length) QSI583wsg camera binned 2x2 LRGB. Aquired in Astroart, stacked in DSS, further aligned in Registar and processed in Photoshop.

This is a first light LRGB image taken with an SBig STF 8300M CCD and WO 110 FLT TMB Triplet APO. Sky conditions were poor on 5-17-13. 10 x 3min L binned 1x1, 10 x 1min Baader Planetarium RGB filters binned 2x2, No flats were used, Nebulosity capture & calibration, Photshop,+HLVG plug-in post processed. A field flattener has since been added to the imaging train.
