Hmmmmm......quite good, at least in these samples.   Although it seems to translate signs into a language I can't understand......

Nice!!  That lens looks like a real performer.  I REALLY liked your Veil shots on SGL, particularly the random L channel shot.

I've used various astro software over the years, but I think only once or twice did I manually stack images.  I do all my stacking with DeepSkyStacker - free and quick to learn.  The resulting 16 bit tiff is opened in Adobe Camera Raw, tweaked and sent to Photoshop for final work.  I typically take 90 second exposures but sometimes shorter exposures for brighter objects like globulars and planetary nebulae.  I've been off work for two weeks and had ONE night suitable for any kind of astro work, and not very well suited at that, upper atmosphere turbulence was horrible and I was doing some imaging of Jupiter.  Comparing the use of a modified webcam to the crop video with a 60D for a Registax presentation with my local astronomy club next week.  I use a 60D, an astro modified 40D and once the weather clears I'll be using a 6D.  I have assorted clip filters for the 40D, they allow me to image from my light-polluted back yard.  The 40D is somewhat noisy and prone to banding, but the trade off is Ha sensitivity.  I gotta believe a modified 6D would be exquisite for astro.

I would love to have a cooled CCD imager, but it's difficult to justify to myself, let alone SWMBO.  Our observing season in the FL Panhandle is just too short, and the CCD would be suitable for ONLY astronomy, unlike a DSLR.

Without tracking, I only shoot wide field or time lapse.  I've got two CG5 GOTO mounts, one carries a C8 and the other a small refractor with a piggybacked camera/telephoto combo.  I've a non-GOTO fork-mounted C9.25 that tracks phenomenally well....but that scope seems to get 5lbs heavier every year.  (I realize this isn't a 'for sale' site, but if anyone with a younger/stronger back is visiting NW Florida and interested yer welcome to come take a look.)

Here's an assortment of images, the Trapezium with un-modified 40D (C9.25 with 2XTC), M51 with un-modified 60D (C8 with f/6.3 focal reducer) and the rest with a modified 40D (300mm/4L or 4 inch f/5 refractor).

Ah.  A comrade!  Some vaguely remember the days before GPS.  I also remember using a LORAN!
Yup - LORAN-A, LORAN-C, Omega and the mercifully defunct Navy Navigational Satellite System (NNSS).  NNSS posited us consistently about 50 miles inland all along the northwest coast of Borneo.  Before this thread I hadn't thought about those days for years.

A gift certificate.  For me.  ;)

Still have the bamboo K&E in a closet.  Lost the Rapidographs years ago.  Still have a David White sextant and sight reduction tables (H.O. 229) I used in the Pacific and Indian Oceans when I was a young man with a full head of black hair.  During a tedious Pacific crossing, I became somewhat proficient with an abacus, nothing's faster for adding and subtracting.  My only experiences with T-squares were during my pitiful attempts at drafting (I was wretched), but I used to wield a mean three-arm protractor in my naviguessing days.  Now you just get lat and long with a Garmin.  Or a 6D!  And both are faster and more accurate.  Shot a Nikon F2 and a Nikkormat back then.

Sounds like someone's view of the world and CR is severely front focused

I checked out her website.  I was underwhelmed.

I may just pull the trigger on the 14 f/2.8 Samyang post Xmas.   In fact, I think I'll rent it first.

Seriously....don't bother renting, just find a good price and buy it.  You will be thrilled, it really is all it's cracked up to be and IMO better than my version 1 Tokina 11-16 was....which was sold when I added a 6D.  Samyang* really did it right.  I also have the Rokinon 8mm fisheye for my crop cameras, it's not quite as optically superb as the 14, but for the limited use a fisheye gets I'm happy with it. 

*As others have noted, it's a Samyang lens, regardless of the name on the body.  I bought the Rokinon version due to the price.

Playing with an old Sigma 400/5.6, one that no longer plays nice with Canon cameras.  At the beach on NAS Pensacola when one of these came by.  I'll have to head down the National Museum of Naval Aviation with my 6D and play with the RokSamBow 14mm, I'll revisit this thread after that.  Not far from here is an Air Force Armament Museum with an SR-71 Blackbird on display....also worth a trip. 

Other photo from inside the museum for a dedication ceremony attended by John Glenn, Gene Cernan, Jim Lovell, Fred Haise and Gene Kranz.   Fred Haise, talking about being ill on Apollo 13 and commenting on the scene from the movie. "I wasn't as ill as they made it look and Jim Lovell definitely did NOT hug me. You don't spend four days cooped up in a space capsule with a Navy guy and let him hug you!"

Picked it up for $279 when buydig had a sale.  Easily the best bang for the buck lens purchase I've ever made.  Waiting on clear skies.......

Google "Sagan pale blue dot".  For me the photo and his words kinda say it all.

Third Party Manufacturers / Re: Rumor: Sigma 16-20 f/2 DG Art [CR1]

That's a narrow range.  f/2?  Really?  On an UWA?  Why?  I'd be happy with a 16-24/2.8.   Just my $.02

FWIW - I'm sure there are a number of shops that can do the work fast and at a reasonable price.  I've used Royal Camera Service in Illinois for lenses and bodies.  Fast and reasonable.  RCS is near Chicago, I'm in Florida. There have been other threads over the years regarding this topic.  You could also ask a local camera shop who they would recommend.  If you can hear/feel that sand while you're focusing you need to do something fast - sand is not the preferred lubricant for lenses.

OK, this is not an accessory but for me "Release Shutter Without Card" is a useless feature, which I never use but can get into trouble real easy ...
Film days, 1975 - I had my beloved Nikon F2 (cost me 1.5 months pay) and was hiking on the south end of Guam.  A trail runs along the crest of the hills providing great views of two postcard perfect bays, a lake in the interior and in general just gorgeous scenery while the ceaseless tradewinds temper the heat and humidity.  I followed a trail that went across to the east side of the island, met a group of boys enjoying the day at a shallow stream with a couple of carabao.  Rode with them through a bamboo forest until we reached the outskirts of the village where they lived.  Realizing I had miles to go to return to my car still on the east side, I resigned myself to a very long trek back.  About that time a pair of Navy Seabees tooling around the boonies in a jeep came by and gave me a lift around the south end of the island back towards where my car was.  We stopped at the ruins of an old Spanish fort overlooking Umatac Bay around sunset, all of us happily snapping away.  'twas just about then I discovered my film had slipped off the takeup spool, not a single shot exposed.........
