I agree with CanNotYet.  I also have a 60D and agree it would be nice to have that 18-250 for the same reasons and situations you mention.  For my money, I'd rather pick up the SX50 instead.  For just a few dollars more, you get a very capable camera with some interesting features.  I'd have a lot more use for the SX50 than I would for that lens.

Ditto on the suction cup mount, it's stupid strong.  I've used it on a motorcycle at, um, a 'tad' in excess of the posted limit and on a catamaran hull.  Rock solid.  I also attach a lanyard.  And I second the tripod mount adapter.

I saw a Brownie Hawkeye at the flea market this weekend.  That was my first camera a 'few' years ago, takes me back to the 'darkroom' in a bathroom.  I wonder if there will be a similar degree of change in photography in the next 50 years - full sensory recording wired to the brain or some such. 

Okay - getting back to the FF/crop discussion.   Again?  Haven't we hashed this out enough?  You say tomayto I say tomahto.

You might also want to get that wineglass squeaky clean, I find that somewhat detracting.

Just an addition:

My EF300mm f/4L (NON-IS) + EF 1.4X II is sharper than my 100-400 f/5.6L

But that's the very old EF300mm f/4L NON-IS which is out of the equation...

I bought a used one of those for astro, it's amazing at f/4.5.  Every once in a while one comes up for sale but for the most part it seems folks just hang on to them.  I know I will.

The operative pharase here is......"But I am confused, do I really spend 3.5K (with the kit lens) for a hobby."   If you have to ask the question, then the answer is no.  The 6D is not 'settling down'....it's a fine camera and should please any hobbyist.  It may please a professional only as a backup body but you're not a professional.  Get it.  Enjoy it.  Buy some nice glass. 

Who knows if they're even going to make a filter for the 6D though because they haven't produced one for any bodies other than 7D and 5D2.

Here 'tis:

I believe the author was a little naive in thinking that the lens would not have to be stopped down for astronomical purposes.  Stars are the ultimate challenge for any lens.  In fact, every lens has to be stopped down between 1 and 2 stops to get good stars in the corners.  As a result, the 200mm f/2.0 still has a speed advantage after stopping down, and the four inches of light gathering ability is nice too.  ;) 


I concur.  The lens excelled for his (way too many) cat, dog and baby photos.  Short of a Schmidt camera, nothing is going to do well for astro at f/2, and it requires a curved imaging surface.  The old 300/4L (non-IS), discontinued now but arguably Canon's best affordable long lens,  has always been considered sharp, but even it is best used at f/4.5 for astro.  I'd love to have a 200 that I can only use at a measly f/2.8 for astrophotos!

Oh and what's the story with your equatorial mount?  Did you make that yourself?

Axilrod - the tripod, wedge and drive base are from an 8 inch Celestron I've had for 35 years, the optics are great but it needed to be on a better mount to reach its potential.  The wood is recycled from another project and the tripod head lives either on this mount or my home made slider depending on what I'm doing.  Older Celestron mounts come up for sale on Astromart once in a while when people transplant the scope to a better mount like I did.  There's another used equipment website I've used, I can't find it with Google but I have the link on my home computer, I'll PM you with it.  Orion sells a small equatorial setup as an intro to astrophotography but it just won't handle much weight.  A used CG5 or SkyViewPro mount for a good price would be an excellent setup, you wouldn't need the computerized version of either.  I use my old C8 mount setup for tracking with up to a 300/f4L.  Setting it vertical I can do panning time lapses.  I've even used it with the mount vertical and the camera pointed straight up in my back yard, the trees rotate around the perimeter of the frame while the stars slowly parade through....would be interesting to try in a place like Joshua Tree.  I'm blocked here at work from getting to the link, it's on YouTube, you should be able to find it with search terms 'emagowan' and 'SkySpin'.

Pansies  ;D

The LSST camera will be the largest digital camera ever constructed, measuring roughly 5' x 10'

« on: January 23, 2013, 09:44:15 AM »
650D/T4i, 600D/T3i and 60D are somewhat similar and will all work quite well.  650D/T4i is a current model which superseded and made (in many peoples' opinions) minor improvements to the 600D/T3i.  The 60D seems to be near the end of its current production life as evidenced by low to non-existent stock levels, a replacement model is anticipated soon.  The 7D, also near the end of its current production life, is also a fine camera and considered by many to be the best of the crop sensor cameras.  A replacement model is anticipated this year.  If I was in the market for any of these cameras, I'd be considering a refurb either direct from Canon or one of the large reputable dealers.  If I was buying for my daughter who was seriously considering a career, my choice for my daughter would be a 6D.  If I was looking for a first DSLR for myself I would either look for one of the refurbs above or spring for a new 6D.   A decision regarding what might be best for you and your daughter is also dependent on what type of photography she has an interest in.  This is a Canon forum and I admit to being somewhat of a Canon fanboy for my reasons, but honestly you wouldn't go wrong with any of the newer Nikon models either.

These were shot from VERY light polluted Pensacola Beach during a public stargaze.  Before and after gussying up to counter the light pollution.  They were taken with a modified 40D using a Sigma 70-200 at 200/2.8.  You can pick up a T3i for a song now and have it modified for astro work.  Plop it on an equatorial mount with a drive and you have a setup that can do some amazing work.  The camera is on my grab and go astrophoto setup.  The tripod and drive base are from an old scope that I have since mated to a much better computerized mount.  Nothing fancy but it does the job and fits neatly in my motorcyle sidecar when I don't feel like lugging the big guns.

Go to the Indian Pass Peninsula! 

I'm in Pensacola, my astronomy club's dark site is in Blackwater River State forest, VERY nice in winter and about a 55 mile drive.  I do astronomy outreach for scout groups that have a campground farther into Blackwater Forest, spectacular skies and very stable air.  I frequently head to Gulf Islands National Seashore and nearby Big Lagoon State Park, they're both very close and dark towards the Gulf, not too shabby overhead.  Our summer skies are very hit and miss and any location is a serious mosquito feed on summer evenings - August is particularly useless, miserable humid and perpetual thunderstorms.  We do somewhat of a 'sidewalk astronomy' gaze at Pensacola Beach two nights per month in the warmer weather, near first quarter moon.  Lots of light pollution but with a modified camera and LPR filters it's surprising what can be picked out.  Meet a lot of interesting folks from all over who come for a few weeks.

Hmmmmmm.....might want to check your AFMA.  You seem to be front focusing a parsec or two..... :o

Excellent work, I'm jealous of those skies.  I have 5 scopes, two cameras (one Ha modified), several equatorial mounts and a home made slider.....and the Florida panhandle hasn't had two clear nights in succession since mid-November....particularly on weekends!  Sheesh - I should probably drop the whole astrophotography thing and take up needlepoint.

EOS Bodies / Re: Yet Another 5D vs 7D Question
« on: January 22, 2013, 09:28:16 AM »
I would think the use of teleconverters would be a significant factor also.  You have not defined what you mean by "...quality of the pic....".  Having said that, I suspect you'll like the photos w/5D3 better - but will find the 7D with that combo is no slouch either.  At the very worst, you'll have better results than you could have achieved 5 or 6 years ago.  Shoot, enjoy and find what works for you.  Hope you can wait til June. :D
