  1. Well after having a couple of disheartening nights out, between finding the brightest stars in a constellation and then using the bins to focus in on them just to try and practice some basic star hopping, only to be greeted when viewing through the bins, many more stars in the same general area, all as bright as each other and not knowing which one is which i felt like i had hit a wall before i've even started. Anyway, thats another story and im sure i'll get there with some practice as i imagine even Jimi Hendrix struggled to hit a chord when he first picked up a guitar. Was another clear night last night (2 in a row, hopefully the start of things to come) i thought i would just go out and goof around pointing at different things not knowing what they are and basically trying to train my eyes into picking out the brighter 'naked eye' stars through the bins. I started off, same as usual in looking at the north star and the plough and found out something i did not know, on looking at the second star across (quick look on google says its mizar) i realised there is another star just above it. I was pretty impressed with that as i had no idea, as ive said i class myself as a very casual observer who just looks at the moon through some binoculars occasionally so my knowledge is very limited to say the least. After seeing that (and a police helicopter flying around that general area) i decided to have a look around cassiopeia and follow the 'pointer' that the 3 stars on the right make to see if could find m31. While looking, a shooting star crossed my field of view in the bins which even tho it was a blink-and-you'll-miss-it thing, was pretty cool to see. I was not getting anywhere trying to find m31 the 'text book' way but since the streetlights were not on and they had turned the spotlights off that shine on the local theatre to where i live the back garden was as dark as i have seen it in a long time so i thought i would take advantage of it. I took my bins and basically just started to scan the general area where m31 can be seen and after a few minutes lo and behold, there it was. I found that i couldnt see it when trying to look directly at it but when looking at a star close by and sort of looking through the corner of my eye, i could see it then (if that makes sense). All it was is a very small feint greyish blob so i can understand people being disappointed when they first see it but not me. I was sat there staring in awe at this light that has come from so far away it was originally projected before humans had even started to walk the earth, and that blew me away. The next thing there were red and green lights coming into my field of view and i realised the police helicopter was still flying around so came back in one happy bunny. The icing on the cake was about an hour and a half ago when i was woken by the milkman so i though i would go outside to catch a glimpse of venus and jupiter and there they were. I wasnt expecting it to look as impressive as it did, even with the naked eye you could just see these 2 bright glows in the sky, with a feinter star just to the right in between them both. I grabbed my camera to try to take some pictures but a 3.2 megapixel camera thats got to be about 10 years old just couldnt capture it, and lack of a tripod didnt help either. Not sure if one can see the transits of venus in 10x50 bins but i couldnt make it out, i could be the bins tho as they have seen better days. Think im going to pop out later to see if i can pick up an adapter for the bins and borrow a tripod so can see a steady view, even with some cheap 10x50 bins well past their prime i guess a tripod will no doubt improve the experience. Sounds stupid but even typing this i had a cheesy grin thinking back on seeing the andromeda galaxy earlier. Looking forward to getting a telescope now to get some clearer views. Sorry for the long winded post and hope everyone else taking advantage of the clear skies last night had as much fun as myself

    DSLR M31

    Hi All, Having had to move to an apartment where I could not use my CPC 1100, I decided that I have to see what I could do with my NexStar SLT 102 (alt-az achromatic 102mm f6.47 refractor). Setting up on my narrow balcony was challenging and the altitude bearing was so loose that it almost moved from the weight of the Canon 700D. I could not see M31 in the estimated 3.5 magnitude sky so I did a two star alignment and used the live-view to focus on a bright star. I then took a 15 second exposure after slewing to M31 which allowed me to see that I had it in the field of view. After a few more 15 second exposures and playing with the motion controls I managed to get it centered. The resulting picture is from 39 subs of 30 seconds at ISO 1600, 9 flats. The images were stacked and stretched with Siril and then I played with the curves on Gimp, cropped and scaled. Not too unhappy.

    Andromeda (M31)

    Never had much luck with this target, however last night (11/09/2016) the conditions were quite good what with the moon setting around midnight, relatively clear skies and M31's position in the sky. I managed to get 8x600s subs before the clouds rolled in - considering the relatively short integration time I'm quite pleased with the result and plan to grab more data as and when possible. Shot under dark skies from Surprise View Car Park in Derbyshire with QHY8L, SWED80, HEQ5, Orion SSAG. Processed in PI and PS. Thanks for looking! Rich

    M31

    From the album: Galaxies

  9. From the album: Learning to use my kit

    This is the first test run of my finder guider set up on my Skywatcher 150PL and EQ3/2 Pro. About an hour and a quarters worth of exposures at ISO1600 (just thought I'd try the higher ISO) with flats. darks and bias. About 30 minutes of 5 minute subs, the rest made up of 3 minutes and 1 minute subs. It seems less noisy than my other M31 unguided attempt. Hopefully the images will get a bit better as I get use to the guiding system.

    M31 - Andromeda Galaxy

    From the album: City View

    This is M31 - Andromeda Galaxy. Another nemesis of mine. This one was a battle as I struggled to get my Canon 600D to image anything I could use. The camera was fine, but I struggled with dew, focus, guiding etc. And I didn't know how to take flats, so this lacks all calibration. The colours are a bit off, but it's my first guided image and I'll keep it as it is as a fond memory of the early struggles. HEQ5 SW120 Canon 600D SW ED80 and MS Webcam guiding 248 minutes in total, and I think 2 minute subs. Edited in Canon Utilities
  12. I currently am on holiday in my father's hometown, a small island near rhodes called symi.Symj, is a pretty small town,with only about 2000 residents.That means that the light pollution levels must be low. Acknowledging that, i called my friends, grabbed my 10x50 bins(that i got for 20€ from Turkey),and went on my way to find a dark site.About after 20 mins of walking (from the city),i stumbled upon a beach, it was dark, so i went in.There i decided to lay on a sunbed that was there.After looking up(not being dark adapted, my friends just kept turning their flashlights on for some reason), i saw the haze of the milky way stretching from Cassiopeia to cygnus and beyond!I was amazed as i ve never seen the milky way before and smudged it off as clouds until i confirmed it was the milky way from an app! The weird part was that at just straight overhead, was the port ,which had many lights, and as a result the sky appeared half bright and half dark. I turned over at Sagittarius and headed over the lagoon nebula. Brilliant! 3-4 stars in a line surrounded by bright nebulosity.(while still being in the haze!) Afterwards i headed to cygnus,it was a real light show! I saw the milky way layering on top of Cygnus while catching a glimpse of m23 and yet again, failing to see NGC7000 . Then, with the corner of my eye, i detected something moving, then turned over to Cassiopeia to see a shooting stsr!(it was my first time seeing one!!!) Was very brief, yet enjoyable. Right afterwards i turned over at the Perseus double cluster.Magnificent! Appeared as 2 small balls of light , almost connected yo eachother. Finally, i realised that finally, the target i was seeking to observe all year long, M31 was into the area with the light pollution! What a shame! While also being low on the Horizon, I couldnt see it with the naked eye. I observed it with ny binoculars for 10 minutes or so . The core was resolved nicely with some hints of outer nebulosity. Overall a great night and now, i wished i had my 8" dob with me.... (Sorry for any granmar mistakes, im currently typing this at 2 am xD)
  13. Hello, This is my first astrophotography with my own scope (and first light for this scope). I've always been fascinated with this galaxy, and it was my childhood dream to capture it. It finally happened ;-) You'll find all the technical details on the description on flickr. Overall it's the first light of my skywatcher Quattro 250mm/1000mm f4, NEQ6, with an unmodded Canon 6D. Integration time: 1h59 Processed with PixInsight. link to flickr for the full resolution and description:
  14. One of my favorite deep sky objects in the night sky, the great Andromeda galaxy. All the processing has been done with Pixinsight. The scope was FSQ-85 with the good old unmodded Canon 6D. Around 5 hours of data with 5 minutes exposure. Hope to add some short exposures to the core someday.
  15. This imaging session, occurring over 2 nights was not without its mistakes and confusion! Setting up the first night I seemed to spend most my time trying to remember how to configure the capture software correctly. The second night I decided not to connect the guide camera to the PhD Guiding 2 correctly and spent 30 minutes establishing that fact. However, out of the jaws of chaos (which extended to the processing of the image) came one of my better efforts on this object. It’s also the largest amount of data I’ve collected with almost 5hrs going into the can for processing. Details Object name Andromeda Galaxy Object ID M31 Date(s) 11 and 12 October, 2017 Telescope Altair 115mm Camera ASI1600MM Luminance 89 x 2 min = 178 min or 2.96 hrs Red 16 x 2 min = 32 min Green 21 x 2 min = 42 min Blue 19 x 2 min = 38 min Ha 0 Oiii 0 Sii 0 Total time 4.8 hrs Frames 0 Processing PixInsight / Bias, Flats, Darks / Masked Stretch / Curves / ATWT I’m having fun zooming in to the different parts of the galaxy to view the H2 regions (star forming) that I was quite surprised to have caught in such numbers. These regions, swimming amongst the sea of big, hot blue stars destined to burn out quickly, are similar to our own Orion Nebula. Moving to the core of the galaxy and it super massive black hole the cooler, longer lived red stars dominate. Up to the left M110, another galaxy bound to Andromeda has resolved quite well – it can off look very pixelated – and nearby the big blue star who’s name I cannot find This galaxy is 220,000 light years across and contains a trillion stars which is twice as many as in our Milky Way galaxy. I think I now need a lot more colour data for this but its a start. David
  16. Hi everyone. I'm back, and trying again to get a decent DSO photo! This is my personal favourite so far, so I must be getting better! haha Still a long way to go with the processing skills, but I'm sure I'll get there. 23x Lights - 120 Seconds - ISO800 20x Darks 20x Flats (Yes! I've started to use these!!) 20x Bias Processed using Photoshop and ProDigital Astronomy Tools Hope you like it. Thanks, Mike
  17. I have been generally pleased with my Moravian camera and filter wheel. However, I noticed I was getting some very odd results when trying to calculate filter offsets for my autofocus routine. I found that the wheel was not rotating to the filter requested - indeed it seemed random. Of course it was not random .... I have a 10 position filter wheel. However, it seemed that the Moravian Ascom driver was convinced I had a 12 position wheel. To get the Moravian wheel correctly configured, you have to run a configuration program. It tells you to do this in the manual. I just hadn't read the manual. As you can imagine, this led to erratic results. If I shot filters in sequence, things would go OK. However, if I tried to go back to a filter I had shot before then it would not work. Now, I shoot the flats from my 7 filters all in one go, BUT I test out the required exposure times first which means a cycle through all 7. So when I come to shoot the actual flats, I am shooting through the wrong filter or (sometimes) through no filter at all. I was never all that happy with the M31 I did back in early December 2016. There seemed an odd gradient on the left side of the image: https://stargazerslounge.com/topic/282827-m31-revisit/ So, having got the wheel correctly configured, I redid the flats and recalibrated the data. Lo and behold, the bright patch on the left disappeared. Data: Baader Blue 36 mm: 16x300" Baader Green 36 mm: 16x300" Baader Luminance 36 mm: 61x300" Baader Red 36 mm: 16x300" Chroma Ha 3nm: 6x1200"
  18. ... I had decided to give up the hobby and recently sold all of my equipment, with the exception of an Equinox 66 with a dodgy focuser. When the bug bit again I added a secondhand EQ5 Synscan and a dslr, and had an evening of no frills unguided imaging on Wednesday. I can honestly say that I enjoyed that session more than I had in a long time, even though the results are somewhat poor! Barry
  19. Hi all, just posting some new pics I took the other night in Saint Barthélemy, at 1633 meters above sea level (very good seeing): M27: M31: IC1396: The usual problems arise: guiding, coma, and noise from the camera (especially visible in the M31, I think). These are pics from 30 73secs exposures at 800 ISO with darks and bias. I did not take flats... Do you think that would improve the noise problem? I'm hoping to construct a flatbox some time... And maybe acquiring a laptop to use for serious guiding. A guide scope would already be available from my astro club... Any thoughts, suggestions would be very welcome! :-) Gerhard.
  20. M31, reprocessed, 5 and 10m exposures 18 frames (don't know the integration time anymore, neither the no. of flats and bias I messed around with this so much).I decided to keep it real on this one (I'm won't to overprocessing in my light-polluted area, so I don't even lose one filament of detail). After changing the file name on the subs,(RAW to Tif), resizing and cropping, I made a gradient removing flat for each of them, and processed them normally after flat application / subtraction. I forewent chasing details in favor of nice values, such as RGB 23/23/23, or as near as I could come to when processing, to find a blend between detail and a pleasing view.
  21. More from my freshly modded nikon D5100, i think im falling in love with this camera M31 - Andromeda by Gareth Harding, on Flickr M31 - Andromeda Scope: Orion Optics VX6 with 1/10 PV upgraded optics Guide Scope: Skywatcher ST80 Guide Cam: QHY 5 Mono Mount: Skywatcher HQE5 Camera: Nikon D5100 Modded Exposure: 11x5 Minute Subs, Darks, Bias & Flats Technical: 750mm f/5 Software: DSS, Pixinsight, PHD, Nebulosity
  22. Hi, This is my first try at Andromeda with the SW Equinox 66, a SW LP Filter and an unmodded 1100D on an HEQ5 Pro with EQMOD. Camera controlled by EOS Utilities. PHD Guiding was with 50mm Finder Guider and QHY5. I used 14 x 5min subs with 4 dark and 22 flats. There would have been more subs if not for an unexpected meridian flip. Stacking was in DSS followed by (too much) PS processing. The LP filter controlled the light pollution but really extended the required exposure time. There are some interesting star shapes but no flattener could explain that. Apart from more data and better processing skills I am not sure where to go from here without spending a lot of cash. The most important thing was the great time I had collecting the data. Thanks for looking Barry
