  1. Had a real struggle taming gradients with this one, lots of light pollution over here makes wide field work difficult, still it is what it is and still better than most UK skies. Taken through a Borg 71FL, the luminance is 12 x 15 sec and 12 x 600 sec using a QHY9 and the colour is 18 x 600 sec using a QHY10. Some of the brighter stars have a curious colour split which I can't remove, if anyone is able to give me a pointer I would be very grateful. Anyway for better or worse here it is, thanks for looking and clear skies. Mike

  2. I'd been keeping an eye on the weather over the weekend hoping to at least get out Saturday night, but the weather had other Ideas. Sunday looked better but work at 5am Monday morning wasn't good .I took the gamble and made the trip up to our usual dark site, joined by fellow society and SGL member Vicky050373. Arriving at around half 7 the sun had already dropped well below the horizon and there was a 50/50 split in the clear skies available. Should I set up or not well with the scope rain cover in the car I put the 22" in it's usual spot. The clouds then started to roll in and by the t

" Nooooo..... get the 16" now lol - they're dead easy to use - it's just a Newtonian on a turntable/rocker box - only bigger - no further experience require. They're fabulous - you can get superb views now and your smaller scopes can start gathering dust like they're supposed to hehe! (Or ignore my addiction to dobs and tell me to go away lol)

  5. A bit naff, but I couldn't sleep last night... came down for a glass of water to be greeted by a beautiful clear sky so grabbed my HTC M8 and held it against the window as still as I could and took 10 x 4 second iso 800 lights and a dark. Thought I'd try it with DSS this morning.

  11. Writing f5 like that you could easily get confused into thinking they were. Astronomers write 16" f/5 this shows that the second figure is the focal ratio of the first figure (which is the diameter of the primary element or aperture), not the photographic speed (f stop or aperture ) of a camera lens which could be written 2030mm f5 Confused yet .....???? What a riot this is eh

  12. So I can't get my 130P into balance due to it being from an AltAz goto mount originally (£30 from astroboot) the tiny dovetail puts the tube in the wrong place with a camera fitted and the wrong rotation also. I acquired a £147 3D printer kit from eBay a week or so ago, and honestly it's required far less fettling than I thought it would to get acceptable prints so within a day or so of it arriving it's producing prints with correct dimensions. So this weekend I printed out some tube rings, designed on onshape - which is a proper CAD package for free and cloud based can't recommend i

  13. Both weather apps promised 6 hours of clear skies last but managed just over one before the clouds rolled in, and stayed! Managed to get two images that both need more data but both are acceptable, to my eyes anyway... M33 is 5 X 10 min, iso 1600, 72mm ED-R, 100D (modded). DSS and PS. The milky way includes NGC 7822 at top right and should also have M52 and the bubble, though I cant see them. 10 X 5.5 min, iso 800, 50mm 1.8 usm lens at F5, Canon 1200D (modded), DSS and PS.

  14. M-31 is the nearest large galaxy and the most luminous member of our local group. It is distant from Earth by 2.5 milion light years and is thought to be as massive as our Milk Way. It has magnitude 3.4 and apparent size of 3.1 deg x 1 deg. This image has been taken from the southern hemisphere ( Lat of -23 deg) in an exceptional night, with a TMB 92mm f/5.5. The luminance sub was 10x600sec and the RGB 5x10min bin 2x2 each channel. Thanks for lookig, Fernando

  15. Not great conditions, but beggars cant be choosers especially at this time of the year! Some reasonable gaps early on, but they didn't last long. Camera and Firecapture both decided to play up as well Celestron ED80, ND5 filter, DMK21au618+No58 green filter.

  17. Hello all, Bodes is a favorite of mine - I had previously imaged this target with a different OTA but was never quite happy with the result. When I obtained the Esprit 120 I decided to give it another go. Comments and critiques welcome - exposure information can be seen here: http://www.meadowlarkridgeobservatory.com/hidden-pages/bodes-galaxyesprit120/ Thank you for looking.

  19. Following on from Gnomus' postings of his processing of the Pacman nebula in bicolour and the Hubble palette it was my turn to have a go at processing the same data. Steve had read about the CFHT (HOS) palette in Warren Keller's new book so persuaded me that I should give it a try. I wasn't sure quite what to expect and was completely unprepared for the wildly coloured image that popped up on the screen when I combined the three colour channels. Unfortunately we discovered that referring to this as Ms Pacman wasn't an original idea but it still seems very apt. I worked mainly in PixInsigh

  21. Just thought I'd share this, a 3-panel mosaic of the Mare Imbrium region taken earlier this year: (click through for original). Equipment as per sig, taken with the QHY through a 2.5x barlow. I really like how you can just about make out Hadley's Rille in this pic, I've always been fascinated by it. I've got a close-up pic of the Rille as well, am currently toying with ideas of how to present exploded detail in a picture. Hope you like, Stuart

  22. A very short run with the Lunt following the white lights earlier on. The usual set up Lunt50mm D/S, DMK21au618, stacked in A/S2 sharpened in ImPPG, finished in C/S2

  23. Progress OK so I selected standard stacking instead of mosaic which knocked 100MB off the FITs file, which then opened instantly in ST. Also set RGB background calibration and got colour! However, I then read an ST instruction which says to set for no colour calibration so trying without that setting now. Anyhoo, a bit rough and noisy but there's colour

  24. Hi. ST works only with linear -un-stretched and uncompressed- files. For DSS ensure you are saving as FITS and have nothing selected for your camera in the FITS dialogue -unless you are stacking FITS files.

  25. Interesting thread.... and perhaps a wake up call for the forum more generally. The way we use the forum (and other fora) is undoubtedly changing and we need to be sure that we don't lose what we have as a result. Personally, I read far more now on my phone or tablet rather than on my pc, and as a result post less (both in number of threads and the number of words!) because it is trickier than with a keyboard (where I am now). I tend to 'like' rather than comment. The forum would rapidly die if everyone was like me! But this thread has also raised an issue I hadn't thought about before.

  26. Hello After processing a film on the subject the result was not good, but he dragged one that ultimately was much better. This is in IR 685 which leaves a little margin to do better with less turbulence. Once again it is my best picture of this area. Good walk over. The lighting in the axis showcases the rilles perpendicular to the detriment of the main rille in which we begin to see details. the lunar Alps were likely formed by a sudden collision that created the giant impact basin known as the Mare Imbrium or Sea of Rains.

  29. Lovely clear skies this afternoon and this evening so got one of each and a high res down the terminator with the 2.5x barlow. Had a beggar of a time processing the daylit moon, brain stopped working but I got there in the end, thanks for the screenshots Charl no darks or flats on the hi res and it shows at fully full size. Also the 3 panes aren't fully blended for levels etc but I'm pleased enough for a quickie. Rupes Recta stands out nicely which goes along with the visual views I had too. A very pleasant PM it was too Daylit Inverted daylit Nightti

  30. Today i attempted for the first time, to stitch two photos of the sun together. The WL shot is taken through an ST80 refractor using an altair GP Cam colour. I ended up taking two videos covering the whole disk, then using Registax, ended up with two photos which i sent to Gimp as layers. I am fairly pleased with how the WL shot has come out. I tried following the same procedure with the Ha scope. However my two final photos didn't appear to have the same sort of colour/saturation/brightness. No matter how i tried to even this up the "join" still shows in this pic. I will repeat this at s

  32. These images were taken on the 7th of October, except for the last one which was acquired on the 6th (worth scrolling down for). The seeing on the 7th was highly variable, whereas on the 6th it was excellent. These are stitched mosaics and single framed shots. The variable seeing prevented me from doing my usual animation on the 6th, this time of AR2599. I actually found AR2598 to be visually fascinating, with its abundant plage regions. Thanks, -Charles

  33. NGC 7640! Unfortunately for this interesting barred spiral it shares it's line of sight and constellation from earth with M31, in Andromeda. What a shame! There is virtually no information on this object out on the internet I could see, it doesn't even have it's own English Wikipedia page! The distances quoted seem to be a mixture of guesses ranging from 19-49 million ly and no mentions at all of the very interesting looking tidal curls towards the right hand limb of the galaxy. It appears that it is roundly overlooked by both professional and amateur astronomers alike. My image is 1

  34. Lovely report Damian, and perfectly sums up a thoroughly enjoyable evening despite a bit of cloud dodging and a bright moon! The views through your 22" blew me away, and it feels like you are seeing objects anew. Just to see the propeller in M13 was something I have never experienced other than from the results of my imaging. You truly cannot beat getting your eye to the eyepiece and enjoying first hand the views that such a scope offers. Indeed, it certainly isn't a 4" refractor lol. It was the first time I had seen some of the objects, such as NGC891, and the scale in the EP was something el

  40. Had a reasonably clear last night so had a second stab at M31. I've got to grips with the Auto Two Star alignment via camera live view much better now. I found a grid overlay option which allows me to put the alignment starts absolutely central and I then carried out a precise goto align on Mirach as suggested by the mount. After slewing to M31 I took a few subs to confirm alignment and it was very good. I stepped up to 30secs exposure this time as per Ians suggestion, accepting that I would lose some subs to trailing. In total I captured 225x30s lights + 50x30s darks. Flats and dar

  41. We had such a great night yesterday with my Xterminator, I thought I'd brag a bit. Tucson Amateur Astronomy Association was scheduled to support the Sunnyside Neighborhood Association's annual Star Night at a special location called the Peace Garden. This is a quiet, isolated 1/2 acre of trees in an otherwise economically depressed high crime area. It was built, and continues to be expanded and enhanced, by the students of Sunnyside School District, supported by the Sunnyside Neighborhood Association. It was the brain child in 2003, and continues under the leadership, of a wonderful lady

  42. I slept most of the afternoon yesterday so this left me being wide awake later on so around 1:30 I peeped outside and to my surprise it was lovely and clear. I wasted no time and got the scope set up, this took a little longer than normal as I had not yet unpacked anything from last weeks SWSP, even so l all was set within 15 minutes and left the scope tracking whilst I went and put some warmer clothes on. I was using a 110mm refractor (baseball bat) 21mm & 8mm Ethos, the conditions were pretty good and had no dewing issues. Even the old metal chair I was using stayed dry. I was

  43. Indeed, no argument - I've been there and done it. When I was a teenager (and to paraphrase Douglas Adams) in a terrible miscalculation of scale I bought a big Dob - a 14" Dark Star. My parents weren't thrilled to lose their dining room to it, and they named it Dusty Bin. But despite that, my dear old Dad would help me load it into his car on clear weekends and drive me up to the dark Northumberland village where my grandparents lived, set it up, then hunker down in the car and go to sleep while I soaked up ancient photons. It was spectacular - but quite an undertaking.

  46. I started preparing at 21:00. Observed until 23:15 when the whole sky was cloudy. Found one side of the house that was out of the hard wind and sat down there. My view of the sky was therefore very limited. I tried to spot Jones1 in Pegasus, but couldn't see it. Then I went seeing the rest of the IDSA fat printed objects in Pegasus. Started with the well known M31. I saw surprisingly much of the whole object. Much more than only the nucleus that I usually see. M32 was also very bright. M110 was very weak in brightness. The rest of the fat printed ones, I saw all of them, altough some only

  49. That's kind of you, thanks for the encouragement! I tried several things to reduce the stars, and in the end I couldn't remember quite what I'd done!! Half the problem is that whilst I did save the image in layers whilst working on it, I didnt save the history, so couldn't replicate my exact technique - AKA random fiddling. I did a star mask layer, as per Doug Gerber's excellent tutorial which helped, but what I really wanted was to replicate a star layer which I'd created with an adjusted (much darker) version of the DSS image. This also eliminates much of the CA on the re
