Because of the twilight this started out as an auto-guiding test but it turned out ok so here it is , the ISO was set low to give me longer times for the test .
5/6/13 slight high cloud coming and going , light winds .
7 subs of 900s at ISO 200 , 200PDS linear mount, canon 60da.
Second rgb image with the OS Veloce RH200. This time is an LRGB of just 10:10:10:10.
The field of view is an amazing 4.5° diagonal!

M13 (NGC 6205) on June 8th, 03:36ut. The Great Globular Cluster in Hercules or the Hercules Globular Cluster, is a globular cluster of about 300,000 stars in the constellation of Hercules. Note: The Arecibo Observatory message of 1974, which contained encoded information about the human race, DNA, atomic numbers, Earth's position and other information, was beamed from the Arecibo Observatory radio telescope in Puerto Rico towards M13 as an experiment in contacting potential extraterrestrial civilizations in the cluster. (Equipment: LX200ACF 12 in. OTA, CGE mount, ST2000xm Ccd, AO8, CFW9, Astronomik LRGB filter set.)
C9.25 with Antares 6.3 focal reducer,QHY 168C and UHC filter was used to collect 10 subs at 60 seconds each. Stacked in Deepskystacker and processed in Nebulosity 4 and Photoshop CS2. Darks and flats subtracted and image cropped.

An impressive LEGO display at Cantigny. A wide variety of themes including the second world war, contemporary urban, and classic television and movies.
Mit schon etwa 60% Mond doch noch M13 fotografiert. Ausrüstung wie immer: OM-1, 300mm f4 mit TC14, Sky Watcher Star Adventurer. 50 min Belichtung, ISO 1250, f5.6. Je 30 darks, flats and biases. Bearbeitung in Siril und Lightroom. Schon deutlich besser als mein früheres Bild von M3.
M13 final
This is a shot of the globular cluster Messier 13, in Hercules. Taken over two nights in the backyard for testing prior to GSSP 2014.
Was challenged to fix some problems with camera and mount prior to the star party. The mount part was easy - I re routed some cables so that they didn't snag. The camera part was not easy. During waiting fo rthe skies to clear, I ran the camera to capture a series of dark frames. Unfortunately, during these sequences a piece of flocking paper fell down into the camera body and blocked the movement of the shutter. The shutter electronics a dead and now it will not open. I've had to hot glue the shutter open and now rely on the motion of the mirror plus the electronics of the CCD to time the exposures. Biggest follow up to the shutter issue has been taking flats. Because short duration flats allow over exposure as the mirror flaps up and down, long duration flats are better. I'm now recording flats with a duration of .7 seconds vs 1/60 second. I may consider building a strobe box to further experiment.
This image is a sum of 18 exposures at 1200 seconds each at 100 ISO.
Standard setup: Stellarvue SV4, Pentax K10D (modified and cooled - and broken shutter), SSF6 flattener
Filter: IDAS HEUIB II
Mount: Losmandy G11 with Gemini 2
Guiding scope: Stellarvue SV70ED with Orion SSAG
Guiding: Maxim 5.24
Exposure control: Star Labs DSLR Shutter and Pentax tethering software
Calibrated in Maxim with 10 darks, 21 flats, and 260 bias
Stacked in DSS 3.3.3 beta 51
Processed in PixInsight 1.8 with Crop, DBE, Masked Stretch, Histogram Stretch to reset black point, TGVDenoise, masked curves to boost saturation and reduce muddy sky glow, and unsharp mask on bright stars to tighten.

M13 Globular cluster in the constellation Hercules. Taken using a Skywatcher ST102 refracting telescope, Sony A57 camera on a Skywatcher Synscan Alt/Az GOTO mount
0.1sec subs, 20 mins total. 12" newtonian, ASI224MC camera.
Not a perfect stack as presence of some blobby stars at edges shows, but very high res for an amateur ground based image.

This is a reprocess of data from last year I had forgotten about using the modded Canon T1i with total exposure of just over 4 hours.
I really miss shooting & the simplicity of processing with a DSLR + the 500D has very low noise. I hope to be testing soon a cooled modded Canon courtesy of my friend Brent Oliver of HyperCams & Mods.
Not as good a result as my image shot with the CCD but In the next image I post you will see what happened when I combined the data from both cameras.

This gigantic slab of Americana looks like it should be wearing the Cadillac or Buick nameplate but is in fact the GAZ M13 Chaika limousine which unbelievably didn't end production until 1981 and only in tiny numbers. This truly superb 1/64 version is made by Welly to be sold in the Russian market under the Autotime brand and is absolutely brimming with great detailing. Curves and fins, big slabs of chrome and bright ornamentation have all been captured even down the wheels making this look more like an adult scale model rather than something sold at nearly pocket money prices. If only Welly would do something similar for the U.K. market! Mint and boxed.
