  1. Had a go at combining data from two imaging sessions a few weeks apart. First was end of 2014, second run was this weekend. Embarrassingly managed to get the framing off by over 20 degrees for the second run, so the image needed some pretty aggressive cropping to carve out the glaring mismatches after stacking. SW ED80, HEQ5, Canon 450D, data gathered on a vintage MacBookPro. In total, 58 x 10 minute subs (just shy of 10 hours). Did vast amounts of darks, bias and flats today under cloudy skies and had my poor PC workstation thrash out the calibration this evening. Stacked in DSS and processed

  3. The Rosette Nebula, a beauty some 5,000 light years away, in Monoceros, aka The Unicorn. This was imaged over six nights between the 19th and 28th of January. Skywatcher 80ED with reducer and QSI 683-WSG with Baader filters Ha: 9 x 1800s OIII: 12 x 1800s I did shoot a load more Ha data on 30th Jan, with a very bright moon, but decided that it was doing more damage than good to the image. It was painful to throw away some five hours of data, but I have learned my lesson, the hard way! I'm pretty happy with this result, though do feel that more data would help to smooth it all out. I am beginni

  4. Hello everybody, So during the full moon, I have tried my Nikon on this nebula and I tried to get simple image but the result is poor because I have little Gradient so next time, I will do some shots on M42 during the new moon. So, for this poor result I have done 35 x 240s + 15 x 30s at 400 iso: Franck

  6. I can't agree with that one bit, maybe one could agrue they have had their day but secondhand are one of the best deals there is to be had . I find the colour cast issue grossly over played and to say they are rubbish is quite frankly rubbish! In my opinion of course. Alan.

  7. Okay not so much a war but i remember the Frankie goes to hollywood song "2 tribes go to war" and thought it would make a good title This is a little shoot out between a pair of Tal 100 f10 achromatic refractors, namely my 100RS and the much earlier 100r, i have never looked trough the 100r before, and i was very kindly loaned this 100r by DougM43, i had to borrow a dovetail to fit this scope to my mount. As most of you will know but for those that dont, the main difference between these 2 scopes is the focuser and the lens, the older 100r has a single speed rack and pinion that will only acc

  8. Hi, A little bit of thin cloud today, but plenty of brightness in the sun and some warmth too, spring must be on it's way. I decided to experiment today, first up was white light, then Calcium K-line and finally Ha with my Quark all taken with a William Optics ZS80. The WL & K-line both looked good but the Ha shots with my Quark were pretty much as always, lacking in contrast, detail and not really sharp. I decided to break out my eyepiece and see what the Quark looked liked visually, pretty much a big red disc, bright but with almost no detail. I looked and after a few seconds the dim

  9. Hi, I made a return trip to Astrofest yesterday, just to see what was new or drool over the solar scopes. The most impressive bit of kit there was the new Lunt 50, several dealers had them on their stands. A Lunt 60 it isn't, it is far smaller, even the pressure tuner is about 2/3rds the size, it is shorter than a PST and may be even a Lunt 35. For entry level I couldn't think of a nicer scope and it would just about fit in a camera bag (handbag Alexandra) if you wanted to take it on hols. I quite fancy one myself to go with the other scope I fancy. Next up was a Lunt 80, these are about

  12. The moon Isn't going anywhere, except to continue it's orbital path around the earth, for a very very, long time to come. Our satellite has prompted much emotion throughout time, Romance, Fear, a Tool for the Harbingers of Doom, In its methodical monthly path around us, its help in regulating our tides, casting light on us in various intensities according to its relationship with the sun and earth. Would we miss it if it disappeared?, of course we would. The moon is a magnificent sight in the night sky, and not too shabby a sight in daylight either. It probably does irritate deep sky imager

  14. I'm with solo above & the other pro-Moon posters. How one could get bored with seeing and observing the surface, mountains and features of another world escapes me. I feel so lucky to have that opportunity. And thankfully, I have no intention of specialising to the extent that I disregard any privilege or opportunity to journey amongst the heavens, Solar System or otherwise...I'm only here once: I value everything, from a faint fuzzy to the lunar alps. I'll be a long time dead so I'll marvel at it all while I can

  17. So we (newly weds) went to South Africa. Three weeks planned around new moon in the dark inland southern hemisphere. Awesome, what a trip! At night however, clouds were present almost every day, giving me only 1,5 night to use the brought along equipment. Bummer. A Takahashi FSQ85 in Pelican case as carry-on, Vixen SP in the suitcase and QSI583WSG camera where taken there for the shots. What an amazing skies! (compared to the Dutch yellowish starless sky) Anyway, I used SGP to do all the stuff automatically. All processing in Nebulosity & Photoshop.

  19. I think these discussions around quality and sharpness can be very misleading. I've not used an SLV, but from John's reviews and other comments I'm sure they are sharper than Radians. It's all a question of degree though. The differences are small, and often masked by seeing conditions anyway. I think the negative points of the Radian were highlighted and discussed on other forums, and then quite probably got out of proportion with their actually severity. To me, they are good, sharp, lightweight eyepieces which I would always be happy to own

  20. Got fed up with my scopes lying around when using my giro for one of my fracs. I therefore ordered two sets of ladder hooks from Ebay for 10 pounds all in. I covered them with pipe insulation and felt and they work superbly. The pic days it all really.

  21. Woke early this morning (4:30am) so noticing it was clear I decided to have a little look around. Vega was high and always easy to spot with It's bright blue white colour and the widely spaced double off to the left making it a familiar sight.Moving on I quickly found M13 in Hercules looking very fuzzy. Looking slightly higher its mini me M92 popped into view. Saturn was up in the south east so I set myself the challenge of working out which constellation it was in. I grabbed my star chart to do it the old fashioned way. Star hopping from Spica at the bottom of Virgo I steadily worked my way a

  24. Finally clear sky no moon.... Quick I have till moonrise at 8pm. At 7.10 I located and sketched NGC 2534 in Lynx....basically left of Caster and Pollux. A faint one for a starter but it was pretty easy with averted vision in my new WO 7mm eyepiece..boy this is a keeper galaxy seeker eyepiece. Then at 7.25 I picked up the brighter but still small edge on NGC 2481 in Gemini itself just below and left of Caster and Pollux....Just think of all those folks looking at the eskimo nebula and missing this little gem.. 7.35 and on to NGC 2350 below Gemini..A very low surface brightness one this.

  30. I've been working very hard solving problems and tweaking the kit over the past few months. I'm finally at the stage where I can start collecting a good set of image data. The scope has been stripped down and rebuilt improving alignment including fine tuning the mirror cell. Ive had a problem for years with the sensor in the camera not sitting completely flat. The scope has a tolerance of 30un so the tiniest bit of tilt in the camera will show. So I've stripped the camera down removed the sensor and re-seated to within the tolerance. I've also had the filter wheel carousel made to fit my 50mm

  31. As a Galaxy and nebula nut it might surprise a few of you to learn I don't mind the moon. I will sit and observe it for an evening or two every now and then and can see the draw it has for others. I seldom observe on moonlit nights now but will make an occasional exception to just go and admire our neighbour in space. The level of detail one can observe is incredible isn't it. I love pushing the Dob about at high power, it feels like your in the lunar module hovering over the surface. Cool

  33. How many of us would be looking up at all if it wasn't for the Moon? As a DSO imager it is the most frustrating thing to see in the sky. But it's the first thing I point a scope to when I'm introducing someone to the nights wonders! Without it would we have had Sir Pat or Neil? I love it and loathe it... But only because it doesn't fit in with MY plans as a DSO imager. So next time I'm cursing it as a pollutant I think I'll point a camera at it & try to learn some new imaging skills instead [emoji3] Sent from my iPhone using Tapatalk

  34. watching a stonking great full moon glowing orange as it peaks above the horison is a sight I never tire of.. Ten minutes later I wish it'd go away so I can get on with some imaging . That said, it's a handy target for those nights with patchy cloud and a pair of bins, A nice thin crescent is also a naked eye treat. make some room on that fence for me Calvin

  36. I made a Bahtinov mask for my Canon 200l and it works a treat but there are a couple of other 'secrets' too:- 1. I bought a 72mm to 52mm filter reducer which stops the lens down to F4 and has a 'knife edge' profile to ensure zero diffraction. This has a dramatically positive effect on star shapes. 2. Choose your focus position carefully, focus on a star at a 1/3rds position to help obviate field curvature (see below)

  37. Hi guys, Decided to go out last night at around midnight, and was out until 3am. This is one of the first of the processing line (so only another 10 to go). Used the Edge800, with the ZWO120mm-s, Baader filters. I did find that my blue channel was a bit lower in terms of quality, but I guess this is what most people get. don't have the details of the capture on my laptop. This is a set of 4 exposures (RGB and a IR pass luminance) all within 2minutes & 30 seconds. to avoid rotation artefacts. I was using OAcapture, and had a bit of an issue with my profile having been deleted, but apart

  39. With today's forecast looking like solid overcast all day, I'm fairly confident I'm not going to be able to replace the cloud at the end of my chart with a Moon image. This was started on the Saturday evening of the Sunderland Astro Jupiter Nights event ( Jan 24th ). It's not a bad record for two weeks and only missing two days. I'll keep going over the next two weeks ( when the Moon is visible ) and see how I can do in a Month. Considering UK weather patterns, I'm surprised I've done this well so far. The original image is 10500 x 3000 pixels.

It was a nice clear sky here in South Yorkshire, took the kids out at 6:35 tonight to watch the ISS go over, then just did a general tour of the stars and constellations with them, my daughter loves the stars, she knows the plough in ursa major, caster and pollux in gemini, orion,the pliedes, cassiopeia. we have also taken a look at jupiter, venus and mars recently. shes 7 and only recently started showing a keen interest in the subject.

  41. To pull images like that out of your data from an evening that you wouldn't normally have tried to image on, were you not testing this software, is very promising! I use PIPP all the time with my planetary imaging and can't wait until this version is released. gnomus: On the PIPP web site, have a look under the Navigation heading, there is a option called Example Usage. Click on that and it gives you lots of different tutorials.

  45. Great fan, I wish we had more Moons! But I'm really a clear skies fan, I don't care if the Moon is shinning like a flood light I can spend hours either observing it or look the other way. What I don't enjoy are the freezing claggy winter nights when dew settles after 5 minutes, my breath fogs EPs, my nose seems to develop a burst water main quality, and my fingers turn stiff and white. If I could have Summer temperatures and dark Winter nights now that would be something. No LP here, so at least with a large Moon I don't bang into things so much. I sometimes go for walks over the fields and t

  48. Once in a while you can see this naked eye from my garden. I love the way it scintillates in the eye[iece when you're observing. Imaging wise it is quite difficult to get a balance between number of stars and colour as the colour washes out of the stars before you get all the peripheral stars. It's a beautiful target though and if you ever get a chance to image it from up North, it's worth the effort. This is one I took a while back and I'm looking forward to updating it when I can. It's only a few frames and it was done with my kit on a wedge so not as stable a table as might be optimum.
