!! Yes, More D3 Astrophotos !!

Hi everyone, I went out again with my camera attached to the telescope mount. I did not use the telescope for these shots, I just used my 80-200mm lens at f/2.8 and ISO of 1000 for a 2:10 exposure.

First up is comet Holmes:

Next is Comet 8p Tuttle and M33, the pinwheel galaxy:

Next is 31, the Andromeda galaxy:

I shot a few other objects with my 85mm which I still have to process, so enjoy these for now.

Here is the set up from last night:

Re: !! Yes, More D3 Astrophotos !!

Todd,

Thanks for sharing, those are great. Soon I'll be doing the same with my D3 riding piggyback on the C14. Are you driving to a dark sky site, or one of the lucky ones who has it out his back door? I'd love to see the full rez version on all of these!

keep these coming Todd - a few questions:

I now have my mount and am in the process of working out the kinks in getting it all set up to work.....have tried a few exposures, but nothing I would dream of posting yet. Your images motive me to keep trying - I plan to struggle along for a few weeks or maybe months, in the meantime will have to see if there is a club in my area where I can elicit some help. D200 now, still on the dreaded D3 wait list.

1. I noticed the Exif listed all those exposures at 160.3". Were those all single exposures or is the Exif misleading me?

2. How dark were the skies for those images? Are you using any light pollution filters? (I suspect not since those are not taken using a telescope)

Re: !! Yes, More D3 Astrophotos !!

Todd,

As a long time astronomy buff, I had no idea that these kind of images were possible with that l just the camera lens.

I've currently got two telescopes, a 12" Cave and 8" Celestron. I would also be interested in getting a motor driven polar alignment setup like you have. I think one of my photography goals for the new year will be to get an acceptable astro photo.

Any recommendations that you could provide would be greatly appreciated.

Hey Ron,

A C14? Cool, you can photograph through that light bucket and get some amazing images, piggyback works too but try shooting some through it. I will post some 100% crops soon, thanks for your comments.

Re: keep these coming Todd - a few questions:

Hi Terry,

The EXIF id correct, these are single exposures. I probably would get nicer ones if I had the patients to stack many of them, but last night was a short night mixed with clouds. As for the sky darkness, umm I guess about a 5.5~6.0 magnitude in some areas of the sky, mainly to the west and south. I did not use any filters for these, just processed them all in Nikon CaptureNX. Here is a non processed image, right out of the camera (RAW to jpeg) with my 200mm lens.

Simply stunning !!

Hello Todd,

Again - a great set of images. They take my breath away when I see what can be achieved with the right gear and the right amount of patience !! Remind me again (though I think you did the last time) what scope are you using and would it be possible to get a photo with it all set up - ie camera and scope together ??

Thanks again - like a previous poster asked - do you have to drive to a location or do you have this lack of light pollution and sky coverage - right at your back door ??

Regards,

Zorpie

Hi Gary....

Well the mount you buy will depend on the amount of money you can spend. The one I use cost approx. 750.00 and it is an average mount, plenty good for using zoom and wide lenses. If you want the really nice ones you can expect to pay $2500 and up on one. This is mine: http://www.celestron.com/c2/product.php?CatID=16&ProdID=92#dealers

I would like this one but it is $3000.00

http://www.celestron.com/c2/product.php?CatID=16&ProdID=93

But if you want the CG-5 mount for just your camera, it will work fine.

Keep em coming Todd... I am not sure if you

ever saw my miserable posts a few months ago with no tracking and perhaps the most light polluted place on earth( new york city)... these were simply my very first try and an actual astro photo LOL... your images inspire me to keep trying. I have got to get a tracking mount and do longer exposures. I want to get those lovely deep and rich milky way shots that can only be achieved with long exposures and maybe (gulp) stacking ... lol ... thanks for the inspiration. (these were actually inspired by some of yours, but I just don't remember when)

The last two were from Northern Connecticut which is MUCH darker...

Re: !! Yes, More D3 Astrophotos !!

Hi Todd,

These are absolutely amazing. Did you have to crop a lot to get the frame?

Thanks for posting.

Re: Keep em coming Todd... I am not sure if you

Thanks Manny for those images, they were cool, I know about light pollution, I am from a light polluted city also and it is hard to get inspired to shoot images for only a few seconds. Keep trying you are doing well.

Hi Vlad, no I did not crop, what you see is a small version of the full image. The D3 does a fine job.

Ok here is a non-processed out of camera image

This is what my images look like before they are processed. You can see I picked up on some light pollution and vignetting.

about telescope

I am thinking about getting a telscope> I don't intend to driving it around. Here where I live, there is a great sky at 3000 ft elevation. so which one would you think I should consider: CS, Neutonion, refractor ?

On the other hand, I do have Canon 500/4 IS, 70-200/2.8 and other WA lenses. Maybe I should just get a tripod you use? I am interested in astrophotography.
Thanks for sharing your experiences.

not bad but then again

its an f2.8! The best optical imaging wide fiels (takahashi fsq-106) is a 530mm F5.0. Thats why I was confused at first, that image looked like one of mine at 5-6min. The faster optics of the 70-200 2.8 means less time the shutter is open. Hey, Todd......What was the longest exposure you took with the D3? Im guessing over 5min heat might start playing an issue......

Re: not bad but then again

I have not done longer than 4 minutes, but it will handle it just fine. 8 minutes on my D200 looked good so the D3 will out preform that camera. Even a 3 minute exposure at ISO 1250 will test the camera as a 8 minute exposure at ISO 400. So far I have not seen any amp glow :^)
