best deep sky objects by month I only got 3.75 hours of data but still ended up with a recognizable image. Was my first proper night guiding, I was thrilled being able to shoot this! How many subs and what total integration time did you have? 3. The biggest issue is that the IR filter built into the sensor for DSLR tends to block a lot of the Hydrogen Alpha (HA) lines that are emitted by the nebula. Ive placed labels of the brightest stars and notable deep sky objects over a wide-field image of the Northern Cross region of the Milky Way. Then I used a generous gift from my colleagues on my retirement to get a cooled OSC with the same size chip. Article: Beginner's Astrophotography: Can I use my unmodified DSLR? Wow great results! Canon T7i, TS 65mm Imaging Star, f/6.5, 41x5min, ISO 400. For an emission nebula like this, an image with a stock camera vs. modified is night and day. I read that conventional wisdom definitely points to Astro modding a dslr for imaging, but last night, I read something on the internet that seems to totally contradict everything else that I have heard and read. Use it with telescopes only and you have no trouble. This nebula doesnt even EXIST with an unmodded DSLR! Its bright enough to capture without an astro-modified camera (sensitive to IR light), and large enough to capture using a small telescope or camera lens. NGC 7000 is a well-photographed astrophotography target, using a wide-field telescope, or a camera lens attached to a DSLR. In pretty poor conditions ( Bortle 6 and I think 80% moon ), Def doable, you just need a couple nights of good data. This means youll be able to record a much larger field of view. Wanted to ask you, why didn't you add a link to a good site that explains what the modding is all about. To Astro mod a DSLR Or Not? - TheSkySearchers.com Your camera still has the stock UV/IR filter in place so no need to add another one in front. This produces smaller, sharper stars. About 4.5 hr integration time, pure,no filters , unmodded.76 mm scope at F4.5. Results Using a $200 DSLR for Astrophotography If you go for a full spectrum mod the chromatic aberration of UV and IR will blur your image when you have a refractor. I fixed the white balance in photoshop and Orion nebula was red. For example all the galaxies in the Coma Cluster will probably have Ha regions but we cannot resolve them. It sounds like your camera is not modified, so the CLS (Not CLS-CCD) is what you want. Also it often sounds like the only way to use a mono is LRGB and narrowband. It was a nightmare to process, however. You can focus very accurate to maximum intensity with this method for a short focal length. The SkyTech Astrophotography Filters are Available at Ontario Telescope and Accessories. Hi Everyone! Until I get the scope, auto guiding, ISO speed and exposure times right with my unmodded Nikon D750, I should not splurge on a dedicated CCD/CMOS camera for the purpose. When the stars are reduced in size during post processing the objects show up more clearly. About all I could tell of the nebula was a faint reddish hue. Also, the stars are small and sharp due to the UV/IR qualities of the SkyTech CLS-CCD filter. Will be nice to see the progress and different looks you can get re-shooting the same targets later with narrowband for example. APO refractors all the way! Framing up the target in the orientation you desire will likely eat up the majority of your setup time. Oh, I added an L-eNhance for fun. Your article has given me hope that I can do a lot with my existing setup! Filters, such as the SkyTech CLS-CCD Clip-in filter make this possible. As it is my post I dare: Bahtinov masks work great for long focal length scopes. An unmodded camera is not totally blind at 656nm. There are some guys making it work with some custom engineering. This certainly makes things more difficult in terms of collecting data, Continue Reading Deep Sky Astrophotography in Light PollutionContinue, The Optolong L-eXtreme filter is now being used in backyards across the globe, which is great news for those that take astrophotography images in heavy light pollution. This astrophotography filter features even narrower bandpasses than last years L-eNhance, making it perfect for nebula photography from the city. The sky came out deep purple. I recently bought a used Canon T5i full spectrum modified which came with the Skytech CLS-CCD clip in filter. The famous Pleiades reside in a blue reflection nebula that does not benefit from a modification either. The mono can be used to take Ha only and mix it into the color data taken with the DSLR or OSC. Sky-Watcher Esprit 100 APO and ZWO ASI294MC Pro. From 2011 through 2014, I spent a lot of time at my local astronomy clubs observatory. Congratulations on a great image, and condolences for enduring the cold! Yes that Astronomik CLS Clip-Filter will certainly help a lot from your red zone. It is the most expensive but it doesnt create the harsh filtering needed for deep-sky close ups in the city. The Telescope used for the photo above (Explore Scientific ED80). Those of you who shoot Milky Way panoramics using a wide angle camera lens will benefit from the LPRO Max filter with its natural sky and star color qualities. Because I stretched it to its limits, I revealed light pollution, amp glow, gradients you name it! I believe the Nexstar 6SE is an Alt-Az mount meaning long exposure deep-sky astrophotography will be tough. Im just getting into astrophotography and my first shot was of the Orion Nebula! Any ideas about that? As a rule of thumb removing the filter enhances the sensitivity by a factor of two or three depending on how the IR filter is designed. I highly suggest you take a shot at this incredible deep-sky object with your camera. Picture Quality: HDR10 and 1080p. That's just not true. You need to be a member in order to leave a comment. Using an unmodded DSLR on one of the hotter nights of the year to boot. Using the filter on my DSLR allows me to capture exactly what I am missing up there. Thanks for the tips! If you are an amateur astrophotographer in the city, a light pollution filter such as the SkyTech CLS will open new doors to your DSLR astrophotography.
