  1. Hi Guys, I thought I would share with you my first DSO taken with my new Orion 8" Ritchey Chretien F8 Telescope. The frame is made up of 12 x 4min shots, no light or dark frames, using my Sony A7Rii camera. The camera had the long exposure noise reduction switched on, which does help to reduce the total number of stars captured by the camera, as the Sony A7Rii does tend to overdo the number of stars captured. The telescope was mounted on my trusty skywatcher NEQ6 mount and the guiding was via PHD 'of course' via my skywatcher ED50 guide scope. The shots were taken from my back garden in Stowmarket, Suffolk where I believe I am a Bortie 4 location, so the skies are mostly dark, with just a little light pollution from the main town, no filters used. My normal telescope is a Skywatcher ED100 Pro Esprit F5.5, which is an incredibly sharp scope, but with a wide 550mm field of view, great for capturing the whole of Andromeda but a struggle with smaller images like the Iris Nebula. I will say the Orion RC scope did need to be collimated out of the box, which was a little disappointing, and it was not just a little out of collimation, it was a long way out, but with the use of a collimating tool, I soon had it dialled in. First impressions of the Orion Ritchey Chretien 8" Telescope are fair, not super impressed, as it is nowhere near as sharp as my ED100 Esprit, but then this is to be expected based on price and telescope type, however, the pictures it has produced are pretty good, if you downscale the full 42MP from the Sony A7Rii camera, as can be seen in this picture. I purchased this 8" Orion Ritchey Chretien OTA mainly for Planetary work, but as yet I have not had a chance to 'get onto' a planet, fingers crossed some clear nights will arrive soon, so I can try. I welcome comments, many thanks Jamie
  2. The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarious. ( click on image to see larger) The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north. Seemingly covering an area about three times that of the full Moon, M8 actually covers an area somewhat greater than 110 light years and is around 4300 light years from Earth in the Sagittarius-Carina spiral arm of the Milkyway galaxy. ...... The frames for this image where taken back when I was very new to astrophotography and I was experimenting with camera settings. On this occasion I wanted to see if JPEG images might be easier to process - I was disappointed with the results. Now that I have a bit more knowledge and skill at processing I decided to have another attempt at trying to process the set because I liked the way the JPEG files had retained colour in the stars. I am reasonably pleased with the result; the faint detail in the nebula is not there but I quite like the colours in the centre and in the stars.

  3. Hello guys,my 8" dob is arriving soon. I have trouble setting my expectations Since i have looked through my 3 " dob its hard picturing what i could see with an 8" one.i live in a light polluted city. Can i look at any dsos directly? How will they look like using adverted vision? What can i expect to see? Also which all around filter should i buy (2") to look at dsos and maybe some planets? Thanks Kronos
  4. What should I buy for a Canon 40D (Astrophotography): a Celestron EdgeHD 8" AVX or a Celestron AVX SCT 9.25" since the price differs only for 100EUR? I want to have nice DSO pictures but be able to see planets as well. Been using a 114mm reflector for 6 years. Thanks in advance
  5. hey people, just got my new telescope delivered. its an 8 inch reflector with a weird looking EQ mount. iam having trouble setting up my telescope. also its hard to point at something, along with that, i see the image rotated at 200+ degrees, near to inversion. any help? how do i proceed? PS: any help with the setting circles would also be appreciated
  6. After thinking about it since around the time I joined this forum (6 months ago or so), this week I've placed an order for a new 8" Orion telescope! This will be my first upgrade in something like 20 years of having a 60mm Celestron. Although I've used it enough to learn the basics of observing, like setting up, the constellations, tracking with an alt/azimuth mount, etc., honestly the most spectacular thing I've seen out of it was M22 after I bought Plössl lenses earlier this year. That was a holdover while I looked for a better telescope I'd be happy with. It doubled the number of stars I could count from about 15-20 to 30-40, but I still have trouble seeing or finding much of anything, and what I do find is dull (in luminosity). So now I can't wait to see what improvement there will be in more than tripling the aperture! Since I live in a suburban area and despite trying really hard haven't found a huge number of celestial objects, I also bought the intelliscope version, which should be greatly helpful in getting started here. Much preferred to using a cell phone that blinds me even on the lowest brightness setting. I'll report back with some first impressions when it arrives!
