Is Nikon D3200 suitable for astrophotography

Recommended Posts

Hi,

Am intrested in astrophotography,but I couldn’t take a single picture with my D-SLR attached to my celestron astromaster 130 Eq telescope...I have Nikon D3200 and if I capture the sky with lens attached the picture is very noisy and not clear...how can I take pictures of galaxy nebulae etc....

 

thanks

I'm sure lots use that model of Nikon for astro..

With galaxy/nebulae long exposures are the key...its just if you can keep the target in the exact spot for the length of the exposure..so if that's 2 mins or 10 seconds it will depend on how much signal is captured during that exposure..i assume you're using the eq mount supplied with the astromaster? If so then it's not suitable for astrophography.

Or is it thst you're connecting the camera and can't get focus?

Hi thanks for reply...if I point towards any star or nebulae ,I can’t even see anything in live view of camera only very bright star like Sirius is seen like a small dot...if I capture without telescope it’s not clear and very white...

Your exposure on a static mount is roughly 400/ focal length of lens with your camera. Assume you use the kit lens the longest exposure would be 22 seconds at 18mm.

Iso probably 800-1600 depending on your local light pollution.

Hello,

    Probably there will be more experienced people than me to answer your question, but i will give you my humble opinion. The camera is not the problem, capturing stars and nebulae, i believe the problem is exposure. Try longer exposures and adjust the ISO accordingly. Experimenting with the exposures and ISOs will eventually lead you to desirable outcome.

 

Clear Skies,

Before embarking on any type of specialist photography...you need to learn your camera first.....shooting in manual for a start...learning that aperture has influence on exposure times and iso speed etc....to me it seems that the op might be trying to run before even being upright.lol.

First you need to start shooting in manual mode.

When looking through the camera eyepiece (or live view)at night to the sky...all you will see is some little dots and it will look rather uninspiring......it's long exposures(camera shutter left open)that allows the sensor to gather in as much light as possible at the widest aperture available within the lens fitted to the camera (most kit lenses have an aperture of f3.5-f4.5 at it's widest at it's shortest focal length and f6.5-f7.5 at it's widest for it's longest focal length.....and enthusiast/pro lens can be anything from f1.2 -f2.8 prime lenses (fixed focal length)and various f2.8 short zoom lenses can be had....these types of lenses are usually quite  expensive.To be able to achieve long exposures towards the night sky you are pretty much constrained to the five hundred rule....500 divided by the focal length of lens (full frame equivalent)...so eg...I shoot with my olympus omd em5 in with a 12-40 f2.8 lens....this is a micro four thirds sensor and has twice the crop factor of  a full frame equivalent so my 12-40 now becomes 24-80....500 divided 24=20 seconds at the lenses shortest focal length and 500 divided by 80 = 6 seconds at it's longest focal length.....if you want all that heavenly glory for longer exposures...a tracking mount of sorts is going to be needed....but I'd suggest getting used  to the camera on a sturdy tripod and getting some night sky shots with just your lens and getting used to how the camera reacts to the various settings....higher iso...longer exposures etc.hope I have been of some help.

Ps..if you want to use your camera to shoot through the scope...you first need to remove your camera's lens and attach a camera mount adapter and t mount to achieve this....but again to get sharp points of light you will be constrained by the five hundred rule.....500 divided by the focal length of the telescope this time as that has now become the lens.

      Hi all,
      For a long time I wanted to shoot this frame, probably from the early days of my astrophotography adventure.
      Finally after all these years I managed to get a decent result of the 'stuff' between these two beautiful nebulae. Fairly happy with the image but always looking for improvement.
      I hope one day to redo this all with a mono camera and filters. 
      Apart from NGC1499 , M45 and the Baby Eagle Nebula no idea what else is in the picture. If you happen to have an idea feel free to educate me.
       
      Some info on image and capturing:
      Widefield Pleiades to California.
      Taken over 2 nights with a total of 11hrs 25min integration.  
      With a stock Nikon d610 and Nikkor 85mm 1.8 objective.
      Tracking was done with the Skywatcher Star Adventurer.
      Lights and all calibrations frames were stacked in DSS.
      Processing was done in Adobe Photoshop CC using Adobe Raw, GradientXterminator plugin, HLVG plugin, Nik software plugins and Photokemi action set.

      Hi everyone,
      I'm looking to get a reasonably portable astrophotography set-up, using a 60-100mm refractor, with a suitable goto mount.  I spotted the Explore Scientifice exos2-gt with pmc-eight goto system, which looks like quite an elegant solution, and wondered if anybody in the forum owns this mount, and what they think of it's performance & usability?

      Hi, I'm keen to buy a small good quality refractor primarily for astrophotography of galaxies and nebulae.   I'd like to use my Pentax K1 full frame DSLR with the telescope.
      Reviewing YouTube & Google the; Altair Astro 72 EDF deluxe & William Optics 71GT look like they might be good models to go for.  I'd welcome the community's views on both, and any other alternatives people recommend.

      Hey all,
      I made an acquisition and processing tutorial a while back (3 years ago? Yikes!) and it is fairly dated in terms of what I'm doing these days. I've been asked for a long time to make a new one showing what I'm doing these days. Specifically how I'm processing a single shot image for both the surface and prominences and how to process them together to show prominences and the surface at once. I've abandoned doing split images and composites and strictly work from one image using layers. Acquisition does not use gamma at all anymore. Nothing terribly fancy, but it's not exactly intuitive so hopefully this new video will illustrate most of the fundamentals to get you started. Instead of an hour, this time it's only 18 minutes. It's real time from start to finish. I'm sorry for the long "waiting periods" where I'm just waiting for the software to finish its routine, it lasts 1.5 minutes and 30 seconds tops typically at first. The first 4 minutes is literally just stacking & alignment in AS!3. I typically will go faster than this, but wanted to slow down enough to try to talk through what I'm doing as I do it. Hopefully you can see each action on the screen. I may have made a few mistakes or said a few incorrect things or terms, forgive me for that, this is not my day job. I really hope it helps folk get more into processing as its not difficult or intimidating when you see a simple process with only a few things that are used. The key is good data to begin with and a good exposure value. Today's data came from a 100mm F10 achromatic refractor and an ASI290MM camera with an HA filter. I used FireCapture to acquire the data with a defocused flat frame. No gamma is used. I target anywhere from 65% to 72% histogram fill. That's it! The processing is fast and simple. I have a few presets that I use, but they are all defaults in Photoshop. A lot of the numbers I use for parameters are based on image scale, so keep that in mind, experiment with your own values. The only preset I use that is not a default is my coloring scheme. I color with levels in Photoshop, and my values are Red: 1.6, Green 0.8, Blue 0.2 (these are mid-point values).

      Hi All,
      Having had to move to an apartment where I could not use my CPC 1100, I decided that I have to see what I could do with my NexStar SLT 102 (alt-az achromatic 102mm f6.47 refractor). Setting up on my narrow balcony was challenging and the altitude bearing was so loose that it almost moved from the weight of the Canon 700D. I could not see M31 in the estimated 3.5 magnitude sky so I did a two star alignment and used the live-view to focus on a bright star. I then took a 15 second exposure after slewing to M31 which allowed me to see that I had it in the field of view. After a few more 15 second exposures and playing with the motion controls I managed to get it centered. The resulting picture is from 39 subs of 30 seconds at ISO 1600, 9 flats. The images were stacked and stretched with Siril and then I played with the curves on Gimp, cropped and scaled. Not too unhappy.
