  1. Hello world, When I first got into Astronomy in August last year, one of the very first DSO that I looked at was M31. I was a bit disappointed in what I saw at the eyepiece, especially when I compared it to the images that I had of the galaxy. I decided to take the family on a holiday to a dark sight in Brittany on a holiday, to see if I could get some pictures. When I plugged my old 350d onto the back of my 127 Mak at the time and took some exposures, I was expecting to stack them and see something amazing. What I saw was not that much better than what I had seen from the eyepiece. At this p

  2. Don't you just love happy accidents? I made a start on Vdb 149/150 a couple of nights ago, and while researching it on the net I discovered that it was right next to Vdb 152, which I had imaged last year and guess what? they join!!!!!!!! So, a bit of a work in progress at the moment due to lack of lum subs but I had to have a go at joining them up. Vdb 149 and 150 are the small blue reflection nebs left and right of the dust column on the left of the image, Vdb 152 is on the right of the image. Stars are a bit dodgy at the moment and loads of noise reduction and photoshop jiggery pokery goin

  5. Already more than a week past by since comet Jacques met IC 1805 in the morning hours of August 20th. But because not before yesterday night I was able to capture the last lightframes of the nebula, for sure I am pretty much the last one to show this conjunction. The number of glitches this time was extraordinary high. At first the optics had been miscollimated because short before I disassembled the OTA for cleaning the primary - when using a fast telescope, of course this means that the outer parts of the images getting awful and partly just useless. Next night, because of clouds I was able

  6. Hi SGL, Well Olly has already posted his version of this region, and here is my one. This is a great part of the sky. I never noticed, or even saw this part of the sky before. The constellation Camelopardalis is invisible from my location in Dublin, and takes a bit or adapted darkness to notice the main stars even from a dark site. This one is one that's going to get the full 30x20inch print out for framing. We had a lot of data, over 30 hours in total, and this remained smooth at full scale. I really love the VBD nebula, they have subtle colour and vary from blues through pinks, and purples.

  9. Here's an image to make everyone else happier about theirs. This is a quick reprocess of my first ever DSO image, about 20 minutes of data divided into 30sec ISO3200 subs + darks. Can't wait to try this again for real, with all the stuff I've learned the last seasons.

  10. The weather forecast has been hardly grim but certainly far from encouraging for the last few days. Today and the next few days are supposed to be dry and moderately warm according to the forecast, but solid unrelenting cloud. Imagine my irritation then, when having had a rather nice steak and a comfortable few glasses of wine, I stepped outside this evening to find a clear sky. In fact not only is it clear, the Milky Way looks drop-dead gorgeous. The "split" through the centre of Cynus is blindingly obvious and the detail visible is quite beautiful. Sadly I've had a few too many glasses al

  12. Very satisfying although I missed out on seeing Mars From my house the south view is naff so I nipped up to the main road junction 1/2 a mile away. Hellish LP but it was barely twilight anyway. Anyway, popped in a 9mm into the 100p (x44) and the moon and Saturn sat nicely into the 1.35 fov. Even got a decent-ish view of the ring, although sadly no cassini division Shortly after the fluffy white stuff rolled and and the evenings over, although thats twice in two short viewing period sessions that the clouds have played ball to allow me to see the intended targets Steve/Baz

  13. Look no mosaic! A quick capture with basic unmodded PST with QHY5-ii cam, single capture of 1000 frames at 20ms, 40fps. Even if you don't get huge detail, it's nice to capture the whole disc on the sensor. Inverted with false colour:

  18. I have finally got to see the sun for the first time in 2 weeks ( mainly due to being on holiday without my solar scope) and what a treat it is today. Surface detail There is that massive filament floating about the centre, this has been mentioned in other posts, but I didn't realise just how big it is. The sunspots are also looking great through the Herschel wedge with lots of sunspot detail available. The seeing is allowing me some quite high magnification, in fact I have gone all the way down to my 2.5mm eyepiece, thus the Penumbra and crochet patterns are excellent. (white light) There is

  20. Hi really nice image!! I'm pretty new to Astrophotography, I have just started my 'project galaxy' with aim to gain the experience of imaging and processing these DSO's as I think they are complex thing to do. My latest 'attemtpt' was M31. My best yet but will still add and add until I get enough data. Taken using my usual stuff: SW 150 PDS, EQ5 Pro Synscan GOTO. Guiding: SW ST80 and QHY5. Modded Canon 600D and coma corrector with CLS clip filter. Using: BYEOS, PHD, DSS, Photoshop CC. M31 - 28/08/14 32 x 240s Lights No Darks - Camera battery ran out and I hadn't plugged in my spare

  21. Shaun, going on holiday without a solar scope? What were you thinking??? ;-) Had some lovely views through the Tak today, very nice sunspots visible and faculae too. Can't wait for my Quark to arrive then I'm back in the Ha game too :-)

  22. Down in Cornwall for a few days with my nephews and had an unexpected break in the weather, so took out my imaging rig to have a go at the Elephant Trunk Nebula. Used the modded 100d at Caradon Observatory and my Super-Takumar 135mm lens. Was quite surprised to find a greenish streak across my image, I thought something had gone wrong with the stack at first. About 38 minutes of 2 minute subs at f4.5 or possibly 5.6. Just stacked, stretched and boosted the saturation in DSS, no other processing. Dark skies make such a difference. I'll have another go at processing it later, and see if I can s

  23. Hi All, This is my first attempt at a mosaic of the Tulip nebula region of Cygnus narrowband HST palette. I find this of Cygnus very interesting I intend to do a lot of this region next year and have ambitions of a huge mosaic, but first things first. With this image I was determined to get to grips with PI's deconvolution as I have always have big problems with ringing, and aslo try out TGVDenoise and Graient Merge Mosaic (Thanks Harry for video tutorials, couldn't have done without them!!) but I still to experiment with GMM a bit more and get it into the correct place in the workflow as it

  24. After a couple of nights trying with camera attached to eyepiece and failing to produce anything worthy of processing, last night the eyepiece got left in the box and I attached the camera direct to the telescope. Had no idea on exposure time so started short at 30 seconds. Each of these is a stack of 30, stacked in DSS, then given a little processing to bring out the detail. Quite pleased with the results will be experimenting again with this setup. All comments/criticisms appreciated ED 80 Telescope F6.3 ISO 1600 HEQ5 unguided

  26. Just made another big mosaic, showing the big filament crossing the disk. Images taken with DMK21+TV Powermate 2.5x and LS35THa with B1200 blocking filter. I used FireCapture for acquisition, Registax and ImageJ for processing of the flats, AS!2 for stacking (240 out of 500 frames per image), Registax for wavelets, AutoStitch64 for stitching the mosaic together, Fitswork4 for sharpening by deconvolution, and finally GIMP for colour. I tried an inverted one for good measure. Quite pleased with the result. I will post links to full-res later

  27. Hi, Rushed home from sailing to get an image of the sun in Ha, but it went behind cloud all too quickly and then went behind the neighbour's roof. Still got about a quarter in clear sky, another quarter through high cloud and the rest was a wash out. The large filament is still impressive though. Robin

  28. Hello! I know that many people - myself included - were so excited by what they saw through their scope, they wanted to share the sights by taking pictures. In the last 6 months (since I got my telescope), I immediately fell in love with the idea of astrophotography and wanted to start capturing the images and sharing them with the world. I quickly learned it involves a good-sized learning curve, and that my equipment isn't well-suited. My telescope is a Carson RP-100 (76mm x 700mm) Newtonian, which serves my "beginner" needs extremely well. It isn't the best, however, at viewing deep-sky

  29. I just scanned 27 images of the transit of Venus and crudely converted them into an animation. These are prints of images taken with my Contax RTS-III at prime focus of the trusty C8 with Thousand Oaks glass solar filter. Should probably be rotated 90 deg and aligned more carefully. Fingerprint removal might also be a good idea. A single full image shows just how quiet the sun was at the time:

  30. I had no idea that the Moon and Saturn were going to be so close tonight otherwise I might have planned to image it better. Just started a night with the lightbridge and stumbled on the most amazing sight. The only way I was set up to capture it was by sticking my dslr lens to the eyepiece and snapping. Not the best shot and I'm sure others will do it better justice but hopefully this shows a bit of the great sight? If you are out at the mo whack a wide field in and take a look!!

  35. Glad you got to see it. It was my first light for my new binoculars and what a way to break them in! All very low down and I had only about 15 minutes with them before they dipped below some trees. They all sat beautifully in the same field, with some reasonable earth shine showing off the dark side of the moon. I could make out Saturn's rings just about even though my seeing was pretty ropey. Mars was quite unimpressive and appeared quite dim. Still, lovely way to break in a new bit of kit and to get reacquainted with the night sky. Sent from my iPad using Tapatalk

  36. back in good old yorkshire where there is internet connectivity. Glad some of you are gettign some sky viewing in. I have been spoilt this last week in Kielder. Here is my latest pic but I think I might have gone over board with the processing slowly getting all sorted but cant wait until we get all get up there for a camping weekend, you will be amazed. I also need to get my HEQ5 up there and get some more pics without trailing

  39. Thanks guys and gals, Some really good stuff out their, must say it is not a easy target. @VikN46 - Not bad for early days, mine where all at ISO800, but I do reduce to F4.5 @Carl - Very nice Mate, Personally I would drop the ISO and up the exposure. @Mike - Always admire what you can get right with a DSLR lens. (Hats off) @auspom - Good crack at it, but looks like it wants more data. @davefrance - Nice one, a bit over stretched for me, also needs more data. @ Phillyo - Nice one mate, hats off! I smell a good season on it's way as it gets darker and colder! Please keep them coming, plus som

  40. Veil Nebula in Cygnus taken in my back garden in Lincoln. Camera: Canon 450D Modded Telescope: WO Megrez 72 APO DDG Mount: EQ6 with EQMod Captured in APT and controlled via CdC. 11 x 10min unguided (had to delete 9 due to clouds), stacked in DSS and processed in Pixinsight then photoshop CS6. 20 flats 20 bias I need to learn how to reduce the stars. Would taking some shorter subs and blending them in as a separate layer work perhaps? Comments/criticisms welcome as always but I'm fairly pleased with it. Phil

  45. PN can be stellar. I find sliding an O-III or UHC filter in and out of the optical path is a great trick to find them, as they seem to brighten compared to the stars when the filter is in place. I have a filter-switch diagonal in my C8 for that purpose.

  47. Why oh why did I ever sell my other EQ6?! I've managed to grab a single ten minute exposure, unguided with the Megrez 72 with 0.8 FF/FR and it's still bang on with tracking! I couldn't believe it! So this is my single 10min exposure, ISO 1600 with the modded 450D. I gave it a VERY quick pop through Photoshop to reduce the brightness with levels and a little curve that's it. Happy boy? I think so!! Phil
