  1. Hi, I recently looked into telescope's & dso's again due to an interesting sight in the night sky . I wanted to get into telescope's etc... but my budget and other things got in the way. This time there's no budget limit (that doesn't mean I'm bill Gates though). My main concern is size since I will carry the telescope with my bare hands (bag). I don't have a local astronomy club or telescope shop around so I don't know if an 8" Newtonian is too bulky/big. Can someone post comparison pictures, if you have an 8" telescope (preferably newtonian, width and length)? Secondly I want to see dso's in the future (firstly beginner objects etc...) so the 8" is more adequate than the 6", but if an 8" is too big then I am okay with a 6" as long as it's much more portable.
  2. I was wondering what images of dso I could get with this setup. How and how much would my images improve if I added in a decent file flattened and what would happen if I exceeded the maximum telescope magnification with Barlow lens.
  3. Hi, After several years in the photography world I decided to take a plunge into astrophotography, haven taken pictures of the moon, I now plan to capture DSO, unfortunately, I live in a bortle 6/7, and was planning to shoot orions nebula but found out it stays below the horizon for the summer. This is why I turn to the forum: are there any DSO that can be easily captured with a DSLR, a tripod and some software like sequator, and that is visible in summer too? Ideally if it can be near the zenith it would be best, due to the annoying sodium light streets. Also if you could post some images of DSO taken with a DSLR and a tripod ( and software of course)that would help me make an idea of what I should expect. The camera I plan on using is an old canon eos 550d, without any modifications. Thanks in advance, S
  4. I've been having another crack at DSO imaging lately, and I've managed to produce this from 6 hours of integration: I'm quite pleased with it but I'm very new to image processing, so I'd be incredibly grateful if someone wouldn't mind having a go at processing my data! Image Info: Lights: 46x4min + 66x3min Stacked with Dark, Flat and Bias frames Stacked in DSS and processed in GIMP Taken under Bortle 7/8 skies Gear: SkyWatcher ED80 0.85x Reducer Astro-Modified EOS 600D ZWO ASI 120MM Mini Guide Camera with 9x50 Finderscope HEQ5 Pro Mount There's some dust bunnies and other artefacts on the image that I know I could spend more time removing, however I'm wondering if I'm doing my data justice in processing! Thanks, Tom NGC7023 (2).TIF
  5. Hi! I've recently acquired a new Astromodified Canon rebel XT and I've tried to take pictures of nebulas using it but I've noticed that there are these weird black artifacts that keep appearing in my images. Would like to know if anyone has experienced this before? Or are these dirt/dust specs on the camera, filter, and telescope glass? I've attached some of my edited and raw pictures for your reference. The black artifacts can already be seen in the raw image of the horsehead nebula and after stacking I think it got amplified. Anyway, advance thanks and I hope everyone's doing well.
  6. So, although I had some issues with my auto guiding (which I found out afterwards) I did manage to get 9x180s exposures and 5 darks of Andromeda and give both stacking (using DSS) and processing (using GIMP). My first attempted DSO.... I am pretty sure that people could get far more information out of the TIFF file from the stack. Hopefully I will get another clear night soon. I am in a heavily light polluted area so I do have a clip in filter on my DSLR which I think took a lot away. More practise needed! Lance

    Dumbbell Nebula

    From the album: Astro Collection

    Love this little nebula, always a joy to look at and always a frustration to photograph as it never seems to go well, with either gear failure or weather getting in the way every time I try!
  11. The Wizard Nebula An emission nebula 7,200 light years away and my first proper project of the new imaging year. Really happy with it as I’ve had a steep learning curve with new kit so really pleased to see this image come together. It’s also the first time I’ve imaged it. 72x180s subs collected over 2 nights 24/25th August in my Bortle 7 back garden, Whitley Bay, England Calibrated with darks, flats and dark flats in DSS and processed in SiriL and Photoshop. Lacerta 72mm f/6 APO ZWO ASI1600MC Pro at -15C gain 200 iOptron CEM25p ZWO 60mm guide scope ZWO ASI120MM-S guide camera Altair Astro 2” Tri Band OSC Filter Data collected in APT and guided with PHD2
  12. The Needle in RGB A beautiful edge on spiral galaxy in the constellation Coma Berenices, around 38,5 million LY from earth. Investigations with the Spitzer IR telescope suggests that the galaxy may actually be a barred spiral galaxy with an inner ring as well. -------- Finally got around to processing my data on NGC 4565 from March. This was one of my "test projects" from this year, where I only shot R-G-B and created a synthetic luminance master from those frames. I think that the most efficient way is still to shoot pure luminance and then just enough R-G-B to get the color you want. Unless one is imaging star clusters, then I think it is totally fine to skip luminance altogether and get as much color data as possible. I will try to do a "super luminance" where I add the R-G-B frames to the luminance stack at some point as well. Shot with my Hypercam 183m V2 and totalling aroung 4,2 hours of data. More info here: https://www.astrobin.com/412663/B/ Comments and critique is always welcome. I decided to put this post in "Getting started with imaging" as it may be interresting for beginners thinking if luminance is worth it.
  13. C11 with focal reducer (1760mm), ASI183mm Pro. Astrodon filters. Mesu 200. Pixinsight. 80 x 60s L 30 x 60s RGB 2.8 Hours data. Thanks for looking. Dave.
  14. Hi, I took this photo during Sep, Oct and Nov of 2015 with over 14 Hours of exposure. This is the longer exposure I ever made on one object, personal record For better resolution: https://www.flickr.com/photos/101543943@N04/22815861829/in/dateposted/ Hope you like it. Thanks much, Haim
  15. I loved processing this amazing galaxy photo. The photos taken during my Namibia travel this year. It was taken during 2 nights. Photo Details: Lum: 18x10Min=3Hours RGB: 8x3Min=24Min for each RGB channel Telescope: ASA 12'' Astrograph F3.6 Mount: ASA DDM85 Camera: FLI 8300 Mono My Flickr Page: https://www.flickr.com/photos/101543943@N04/ Thanks for watching, Haim Huli
  16. NGC281 - The Pac-Man by Chris Kennedy, on Flickr 35kph gusts of wind, and REALLY bad guiding due to a lack of drift align and the star being "blown away", but managed to get a little something out of 30x360s light frames, also a new target for me, one I want to come back to under better conditions and with other wavelengths of light to make a full colour image.
  17. Hi everyone, i am looking to buy a budget level lens for Christmas to begin astrophotography. I am a beginner observer and am dying to get into imaging. Nothing major to start with, I'd be very happy to get decent images of Orion and andromeda. (My dslr is unmodified) If anyone had any examples of pictures they'd taken with these sort of lenses I'd appreciate it. ive seen some on here from budget lenses and am very impressed. Would love to get a few more samples though. Thanks very much ?
  18. Hi there! (Before reading, my English may not be the best, but I hope you'll understand what I mean and say) I'm currently looking for a telescope that will blow my mind (in a weird way). I've been a "fan" of the night sky since I was a little kid, now I'm 21 years old and I want to give the skies a try. So, the telescop I've been thinking about buying is the Sky-Watcher Explorer-150P(EQ3-2) F/750. To me it seems like a decent telescope for a beginner, but I have my questions to those who are experienced with telescopes and those of you who maybe own their own Sky Watcher Expl. 150P. Questions: 1. Is this a good beginners telescope? Please explain why it is, and why it might not be. 2. What will I be able to view with it? 3. Is this a telescope I can use to take pictures? If so, how can this be done? (Using a laptop or a digital camera?...or both?) 4. Is it difficult to take it with you and to operate it? 5. If you could please rate it from 1-5 (for beginners), where would you put it? Those are the questions I have right now, I might come back with more later. I'm hoping for friendly and informative replies that can help me decide. It's already pretty late here in Norway, so I'll be going to bed now, but I hope some of you can answer me within the next few days. Here's a link to a website I might be buying from: http://www.stjarnhusetonline.se/prod/telescopes/sky-watcher/newtonianreflectors/explorer150.html Have a great night. Much love from Norway.
