    Post Nikon D5300 astro mod



    I was using my D5300 with great success and was able to get some good images with it.
    But i have noticed that some H-alpha dominant nebulae like Rosette are very hard to capture with it due to the low pass filter in it cutting off most of the H-alpha signals.
    So i have finally decided to self mod it so i can use it and my new setup to its full use.



    What i did is a full spectrum mod. I have followed the lifepixel tutorial to open up the DSLR and remove the filter. https://www.lifepixel.com/tutorials/...rsion-tutorial
    For the last step i have left it without any filter or glass (need to add a clear glass later since sensor is directly exposed).
    Since it has no filters now, its sensitive to wide range in the spectrum including IR and UV so need to use an IR/UV cut filter to cut off them. I'm using an Optolong 2" UV/IR cut (60$~) which seems to work fine. Also i have a Svbony 2" UV/IR cut (18$) that i have not tested yet.



    If you want to self mod it, you need to carefully open the DSLR, there are lot of fragile cables that need careful handling, also you will have to de-solder two wires attached to the filter to remove it. After removing the filter, you need to fine tune 3 pins that holding the sensor to get it correctly autofocus with motorized lenses. so if you are not comfortable doing it, you can always send it to lifepixel or somewhere so they can professionally mod it.

    Also i have created a custom WB profile. To do this, you just need to take a photo of a gray background ( i have used a gray car door under noon sun light) with the filter attached and camera will use the sample image to create a custom profile. This must be done to calibrate colors correctly. https://imaging.nikon.com/support/di...etmanual1.html

    If you need to shoot normal day time photos, you will have to use UV/IR filter for each lens. they don't cost much. generic filters are like 10$ and you can find branded filters from 25$.

    Full spectrum modded D5300 + 55-300mm Nikkor at 55mm. As you can see, custom WB with UV/IR lens screw in filter is giving natural colors



    After the mod i was able to test it on a dark site. results were pretty good but i couldn't gather enough data to finish any work.

    All images are quick processed images without flats/calibration frames.

    Flame + Horse head
    1st is only 15min (5mX3) with new setup, other one is 50min of data at home with old setup ( setup info are on signature)


    15min (5mX3) with new setup


    50min of data at home with old setup

    Rosette
    1st is only 30min (5mX6) with new setup, other one is 2 hours (3mx19,5mx14) of data at home with old setup ( setup info are on signature)


    30min (5mX6) with new setup


    2 hours (3mx19,5mx14) of data at home with old setup


    As you can see the H-alpha data (red color) is improved a lot than before. So modding a D5300 is a good idea if you are thinking about it.

    Fabulous write up and documentation geethq!

    I looked on the lifepixel sight and they don’t have an article for modding the D3300, but it might be similar to the D5300. Not ready to open it up just yet, but I appreciate the work and time that you put into this thread.
    Big time difference in results and very nice comparison.
    Maybe later in the year after I get more AP experience, I will look into picking up a used D3300 body to modify for AP use only.
    Thanks again for the excellent comparison work!

    What a great difference! I admire your fortitude in taking apart the camera. I don't think I have the courage for this particular mod

    Well done geethq. I agree with bobharmony on tackling such a project, I would be inclined to send it out to a well-known source.

    Fantastic results.

    Was it a difficult mod? Also do you know where you can buy suitable full spectrum glass to cover the sensor or are you not going to bother?

    Great information! but you have convinced me to rather leave my D5300 as is. I have had some bad luck with a ccd camera that I want to use for guiding : its protective filter got a crack in it and I have removed it and have ordered a UV/IR cut filter to replace it with and it looks like (according to your data) that it should work fine. It has me wondering if there is a ideal filter to use for a guide camera, one is not really worried about color hues just good contrast from the best part of the spectrum to track stars with?
