So I am fairly new to the hobby, what I mean is I have a Celestron Astromaster 114 right now but its hard to use because of the non computerized equatorial mount as well as the red dot sight is bad. I am mainly interested in looking at DSO’s because they seem very interesting. My question is should i get a refractor or sct for observing dso’s and sometimes planets? I want a computerized one with tracking so I don’t have to take a long time finding nebulae and galaxies. Also, is there a certain type of filter to see color on nebula when not using eaa and just viewing with your eyes? I am looking to spend between $600-900

thanks,

Hi,

i think this telescope will check most of your boxes, i guess you can do some EAA with it and/or livestacking, but keep in mind this is AltAz, so there will be field rotation.

M42 is probable (i could be wrong) the only DSO where you can see a hint of color, but don't expect miracles.

Filters like a contrast booster or Oiii for visual just provide some more contrast so the DSO is a bit more defined, but they work best in large aperture scopes, 8" might be not big enough to gain something with a filter if you are not in a dark location.

I have the manual version of the 200P Dobsonian linked to above. It’s a great telescope for deep sky observing as well as the Moon and planets. I think that if your main interest is DSOs then get the biggest aperture you can afford yet can still comfortably move around. 
 

You won’t see colour in most nebulae because they are too faint for our eyes to detect colour. However, I’ve seen a hint of green in M42 (the Orion Nebula) and some planetary nebulae show subtle colour also. 
 

Keep in mind that dark skies make the biggest difference when observing galaxies and nebulae.

      After a 20 year long hiatus - my last astrophoto was captured with a film camera in 1997 - at the beginning of 2020 I decided it was time to start again.
      So, January 25th 2020 I brought home my used Sky-Watcher NEQ6 Pro and I immediately started taking photos. Obviously, my first target was M42 in Orion.
      This was my first digital astrophotography. 31 subframes, 30s each, taken at ISO800 with my unmodified Nikon D90, Nikkor 70-300mm at 300mm f/6.3 - January 28th, 2020, home front yard, Bortle 5/6 sky, no guiding, no filters. A grand total of 15.5 minutes...

      A couple of weeks later, me and my wife went to spend Valentine's weekend in the mountains. Of course I couldn't avoid taking advantage of the Bortle 4 sky and I took all my gear with me. Same target, 52 subframes, 45s each, taken at ISO800 with my unmodified Nikon D90, Nikkor 70-300mm at 300m f/5.6 - February 14th, 2020, Tonadico, Bortle 4 sky, no guiding, no filters. 39 minutes total integration.

      After I finished post-processing the second photograph, I was so happy with the result. It felt amazing that I was able to capture so many details and more nebulosity compared to the photo taken from home.
      Months passed, gear was changed. First one being the camera: at the end of February I bought a Nikon D5300 and a couple of months later I astromodified it on my own, adding a UV/IR cut filter in front of the sensor, after cutting it to size.
      In October the rest of the setup finally arrived: Tecnosky 80/480 APO FPL53 Triplet OWL Series imaging telescope, Artesky UltraGuide 60mm f/4 guide scope and ZWO ASI 224MC guide camera. Also, an Optolong L-Pro 2" light pollution filter.
      After months of imaging and getting more experienced with PixInsight, it was just a matter of waiting before I could have another go at one of my favorite targets. And maybe give it a little more justice.
      This project took me more than a month, due to the rare clear nights opportunities I have had here lately.
      I started acquiring in January and finished a couple of weeks ago.
      M42 taken over 8 nights, under my Bortle 5/6 sky.
      Total integration time: 18h 04m 00s for the nebula. 714s (14s subs) + 2065s (35s subs) for the Trapezium and the core.
      Here are the acquisition details:
      Mount: Sky-Watcher NEQ6 Pro
      Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
      Camera: D5300 astromodified
      Reducer/flattener: Tecnosky 4 elements, 0.8x
      Guide-scope: Artesky UltraGuide 60mm f/4
      Guide-camera: ZWO ASI 224MC
      2021/01/12: Number of subs/Exposure time: 33@300s. Notes: L-Pro filter, no Moon
      2021/01/13: Number of subs/Exposure time: 33@300s. Notes: L-Pro filter, no Moon
      2021/01/15: Number of subs/Exposure time: 38@300s. Notes: L-Pro filter, Moon 8% illuminated
      2021/01/18: Number of subs/Exposure time: 36@300s. Notes: L-Pro filter, Moon 30% illuminated
      2021/02/13: Number of subs/Exposure time: 30@300s. Notes: L-Pro filter, Moon 4% illuminated
      2021/02/14: Number of subs/Exposure time: 23@300s. Notes: L-Pro filter, Moon 9% illuminated
      2021/02/15: Number of subs/Exposure time: 51@14s + 48@35s. Notes: L-Pro filter, Moon 15% illuminated
      2021/02/17: Number of subs/Exposure time: 11@35s + 38@180s + 1@300s. Notes: L-Pro filter, Moon 30% illuminated
      Total exposure time (main integration): 65040s = 18h 04m 00s.
      Total exposure time (35s integration): 2065s.
      Total exposure time (14s integration): 714s.
      Pre and post-processing: PixInsight 1.8.8-7.
      Full HDR Version:

      Masked Stretch Version:

      Blended Version (50% HDR + 50% Masked Stretch):

      To my personal taste, I like the blended version the most. I think it brings out the best of both worlds (HDR and soft, less contrasty but more colorful look).
      I must say, I am very pleased and happy with the result. Not to boast, but I think I have come a long way since I started.
      Obviously the better gear and the much, much longer integration time helped.
      I think I actually spent more time post-processing it than acquiring it. Especially since I had to do the work almost twice: I post-processed the HDR and the Masked Stretch images separately, making sure I used the same processes and with the same strenght in both, so that I could combine them effectively, if I decided I didn’t like the look of the HDR alone. I also think I managed to tame the stars a lot more, compared to my previous post-processing attempts.
      As usual, here’s a link to the full resolution image(s): Orion Nebula (M42), De Mairan’s Nebula (M43) and Running Man (NGC 1977)
      Thanks for looking!

      Hi I've got an 8" dobsonian and I just got a dslr to connect to it. Obviously there's no tracking so what kind of things can I capture. Will I be able to do dso and planets?
      Thanks

      I am looking to return my Powerseeker 114eq and get a XT6. I know that my canon rebel T4i will not reach focus. It wont travel enough inwards. I want to know, which is best? Plan A is trying to use Barlow or eyepiece projection. Which will magnify less, eypiece or barlow? Are there any tips for both of tose methods and how to use eyepiece projection? Then, Plan B is moving the mirror. I cant find any good tutorials either. Thanks in advance.

      I would like to share my fourth image.
      With my "lucky week" of imaging, along with M33, I managed to finish also this project. This is my longest integration to date.
      These are IC 405 and IC 410, also known as the Flaming Star Nebula and the Tadpole Nebula, respectively, taken over 7 nights, under my Bortle 5/6 home sky.
      Total integration time: 18h 29m 00s.
      Here are the acquisition details:
      Mount: Sky-Watcher NEQ6 Pro
      Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
      Camera: D5300 astromodified
      Reducer/flattener: Tecnosky 4 elements, 0.8x
      Guide-scope: Artesky UltraGuide 60mm f/4
      Guide-camera: ZWO ASI 224MC
      2020/11/18: Number of subs/Exposure time: 41@240s + 1@300s. Notes: L-Pro filter, no Moon
      2020/11/21: Number of subs/Exposure time: 48@300s. Notes: L-Pro filter, Moon 46% illuminated
      2020/11/24: Number of subs/Exposure time: 48@300s. Notes: L-Pro filter, Moon 75% illuminated
      2020/12/07: Number of subs/Exposure time: 15@300s. Notes: L-Pro filter, no Moon
      2020/12/13: Number of subs/Exposure time: 22@300s. Notes: L-Pro filter, no Moon
      2021/01/10: Number of subs/Exposure time: 37@300s. Notes: L-Pro filter, no Moon
      2021/01/11: Number of subs/Exposure time: 18@300s. Notes: L-Pro filter, no Moon
      Total exposure time: 66540s = 18h 29m 00s.
      Pre and post-processing: PixInsight 1.8.8-7.

      This image was particularly hard to process, since there are many bright stars and stretching the nebulosity while taming the stars was quite difficult. I am sure I didn't manage it as well as I would have liked.

      I would like to share my third image.
      I finally had a "lucky week", since my last session, December 18th. I managed 5 clear nights out of the past 6 (has to be a record, at least for me and my area) and I was able to finish a couple of projects I had started long ago and start a few new ones.
      This is M33, also known as the Triangulum Galaxy, taken over 10 nights, under my Bortle 5/6 home sky.
      Total integration time: 10h 14m 00s.
      Here are the acquisition details:
      Mount: Sky-Watcher NEQ6 Pro
      Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
      Camera: D5300 astromodified
      Reducer/flattener: Tecnosky 4 elements, 0.8x
      Guide-scope: Artesky UltraGuide 60mm f/4
      Guide-camera: ZWO ASI 224MC
      2020/11/08: Number of subs/Exposure time: 11@240s. Notes: L-Pro filter, no Moon
      2020/11/09: Number of subs/Exposure time: 10@240s. Notes: L-Pro filter, no Moon
      2020/11/20: Number of subs/Exposure time: 15@240s + 4@300s. Notes: L-Pro filter, Moon 30% illuminated
      2020/11/21: Number of subs/Exposure time: 22@300s. Notes: L-Pro filter, Moon 45% illuminated
      2020/11/24: Number of subs/Exposure time: 20@300s. Notes: L-Pro filter, Moon 75% illuminated
      2020/12/13: Number of subs/Exposure time: 12@300s. Notes: L-Pro filter, no Moon
      2020/12/14: Number of subs/Exposure time: 8@300s. Notes: L-Pro filter, no Moon
      2020/12/18: Number of subs/Exposure time: 6@300s. Notes: L-Pro filter, Moon 20% illuminated
      2021/01/10: Number of subs/Exposure time: 9@300s. Notes: L-Pro filter, no Moon
      2021/01/11: Number of subs/Exposure time: 15@300s. Notes: L-Pro filter, no Moon
      Total exposure time: 36840s = 10h 14m 00s.
      Pre and post-processing: PixInsight 1.8.8-7.

      Image was Drizzle Integrated and then cropped to original sensor size (6016x4016), without resampling. So, it appears as if taken ad double the focal length (768mm instead of 384mm). Image scale 1.04 arc-sec/pixel.
