  1. Hello everyone, Bit of a backround: I've been a keen stargazer when in my teenage years, then couldn't pursuit my passion, but recently, in my forties, it hit me again, as I moved and life is good (South facing large garden, obstructed only from the North by our house, but then I just move the scope further and viola!). Started with 90mm refractor, but was always thinking of reflector. Long story short, I've got my SkyWatcher Star Discovery 150P GOTO a week ago. Bought it second hand, very good condition, and good mirror. Have got two nights stargazing, cought cold and I AM LOVING IT. Now I would like to get me a nice wide angle ep for DSO spotting. The scope is 150mm / 750mm f5. I've done some reading obviously, and Explore Scientific 82 degree series have all good reviews and fit within my budget. I can afford only one, and apparently the best for DSOs is the one that gives 2mm exit pupil. Now, for my scope that would be 10mm piece, and that is not within ES 82 degree range, so it's down to 11mm (2.2mm exit pupil) or 8.8mm (1.76mm exit pupil). My question is: which one would be better for my rediscovered passion? I'm gonna be using that ep for faint mostly. Thanks to everyone in advance for any kind advise.
  2. 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
  3. 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.
  4. Hi everyone - it's been a while! This has been on my hard drive for almost 2 months and I finally got round to processing it...it was quite optimistic of me to try and image this from my Bortle 7-8 back garden, but I gave it a go! While the nebula itself is clear to see, all those gorgeous dust clouds surrounding it were extremely hard for me to capture from my location without a lot more integration time. I think I'll head to dark skies to capture this one next time, along with some more focal length! LRGB shot with ASI1600MM Pro and WO Z73. 2.9 hours of integration time. Full details here. Thanks for looking!
  5. This is a recent edit of data I collected back in January. Image is taken with a Canon 450Da and Canon EF L 70-200mm f/2.8 lens sitting on a Sky-Watcher Star Adventurer. It’s quite a large crop from a 200mm frame. 25 x 3 min guided subs. Stacked in SiriL and processed in Photoshop. Image taken in Northumberland under Bortle 3 skies.
  6. Hi everyone! The Tadpole Nebula and the Flaming Star Nebula captured over three nights of the unexpected nice weather we had a couple of weeks ago. A number of firsts with this image: 1. My first mosaic - keeping it simple with two panes! 2. First time I left my imaging rig outside... (I used a telegizmo cover) and it was perfect, allowing me to get imaging very quickly on each night 3. First time using powerful scripting tools in my capture software, APT, to move to the second pane and starting imaging automatically...worked really well! APP was used for pre-processing and stitching the mosaic together, while Pixinsight was used for image processing. A total of 10.9 hours integration time. Full details on Astrobin Thanks for looking!
  7. So been at the this imaging malarchy for a couple of months and sometimes things just don't seem rational. Why do I get better results from 30 x 300s subs than from 15 x 600s? I suspect that it is the signal to noise ratio of the longer exposures. i.e DSLR noise increase with exposure time. But maybe I am missing something?
  8. Been really busy with university applications lately, but after watching Star Gazing Live last night I felt inspired to brush the dust off the scope and get imaging. Didn't get nearly as much exposure as I'd hoped due to mechanical problems, but was very happy with my polar alignment. Almost getting the hang of this stuff! Anyway here it is, my first go at M42, in JPEG form, with some very quick and basic post processing in DSS. Not happy with the clarity of the image, it appears hazy to me? And the core appears kinda burnt out. All feedback appreciated(: Scope: Skywatcher 200P Camera: Sony Alpha A-57 25 lights at ISO 1600 and 30s each. 12mins 30secs exposure time. 28 darks No flats or bias
  9. Hey SGL I was wondering in what order to processes DSO, and if different types of DSO require a different order. This is still basic, so 1 set of lights, single shots (aka not using filters to split colours), etc. Tutorials suggest: eg BudgetAstro DSS Align Colours Remove Vignetting (PS if no flats taken) Star Mask Levels Curves Match Colour / Reduce Noise / Sharpen I notice before I watched the BudgetAstro videos, my pictures turned out to be more vivid, when is Saturation done?
  10. 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
  11. 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.
  12. 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 ?
  13. 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.
  14. First time viewing and photographing this object - think I've found a new favourite to observe! My day was filled with heavy rain and whilst the sky did mostly clear, lightning could be seen in the distance and a mist left me with extremely condensated equipment, to the point where my laptop hit a BSOD with the mouse no longer functioning - so crossing fingers that after 24 hours of drying, it will be fine! The next time I attempt this object, I feel a nice 2x barlow will be in order, or even perhaps a 3x.
  15. 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.
  16. 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

    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!
