I set up my Camera 70D for some live-view moon photography, that is captured in the video.If you’re getting started in deep-sky astrophotography, I believe that a compact apochromatic (APO) refractor telescope is the best possible choice.Ī compact APO refractor is portable and lightweight, making it a smoother transition from the camera lenses you may be used to. On this night, there also happened to be a beautiful, thin, waxing crescent moon setting in the evening before my imaging session. I also dive into some aspects of my viewing area, and the amount of light pollution and trees my backyard sky suffers from. I filmed a video on my Youtube Channel documenting my night in the backyard shooting the Needle Galaxy. The difference is subtle, but you can now see more of the small surrounding galaxies in the area.

Here is a version of my image from the initial 1 hour of data captured on April 10th for reference. I just couldn’t resist pulling out more color and details from this striking little edge-on spiral galaxy. This is about as small a galaxy as I can realistically photograph with my 80mm telescope. The Needle Galaxy is about the same size as the Whirlpool Galaxy, although it is on its side. Larger instruments such as an 8″ SCT would be much better suited for capturing a galaxy of this size. The small apparent size of NGC 4565 in my 80mm refractor telescope made this a challenging photography subject for me. I photographed the Needle Galaxy over 2 nights in April 2016 from my light-polluted backyard. This is a great technique for giving the image more depth. Widefield photos of galaxies like this can really showcase the imperfections in your background sky.įinally, a selective amount of the “less crunchy, more fuzzy” action was applied to only the brightest stars in the image. This was especially effective at removing the wavy color variations in the background sky color. I also used the gradient removal technique, as shown in my Photoshop tutorial. The reason I mask the galaxy when applying this filter is to make sure that the brightness or detail of the DSO is not lost in the process. Using the Astronomy Tools Action Set, several iterations of the “make stars smaller” action were applied, with a mask on the galaxy itself. It’s cool enough to keep your DSLR sensor at a reasonable temperature, but not cold enough to numb your fingers while outside! Image Processing Techniqueįor this image of the Needle Galaxy, importance was given to star reduction and color. Spring is a great season for astrophotography because of the long nights and mild temperatures. The early Spring temperatures helped keep my camera cool when photographing the Needle Galaxy.

Total Exposure Time: 2 Hours, 31 Minutes (43 x 3 Min & 4 Min Subs ISO 1600) The Needle Galaxy with an 80mm Telescope NGC 4565 – The Needle Galaxy The following article outlines my experiences capturing the Needle Galaxy with my 80mm refractor telescope and DSLR camera. Adobe Photoshop was used to process the final image, with an emphasis on color balance and clarity of the galactic disc. The images were stacked (each filter separately) in DeepSkyStacker using dark frames to calibrate the images. I collected 20 x 3-minute images through each LRGB filter using a ZWO EFW.
