  1. Im planning to give up on this hobby and will donate to anyone who is looking for astro stuff. so yes, its free. €0,00 it can be collected when you keep the social distancing in mind or it can be shipped Skywatcher eq8 pro (pending) Skywatcher esprit 120 Celestron edge hd 14 incl reducer Zwo 2600Mc Set of Televue 3.7 and 17 Ethos. Boxed. (I will post pictures later tonight) all Items are in mint condition and bought in 2020. If all taken at once i can throw in a basically unused 2” narrowband filterset *The Eq8 pro has a new owner already, *other items still available!

  2. Here is 6.4 hours on NGC 3198, a barred spiral galaxy in Ursa Major. It is some 47 million light years away and was discovered by Lord Rosse sometime before 1850. Did this just happen to drift across the FOV of the Leviathan of Parsonstown I wonder, or did he have a more user friendly scope for sweeping the sky at his disposal? This was captured over 4 sessions, trying to avoid the moon and frequent high cloud. Most of the data was binned 2x2 but in error I took some Lum and blue data at full resolution. However, after suitable calibration this was combined in APP no problem. The star to the lower left of the galaxy that looks like it's trailed is a binary, they were resolved on the individual subs but have merged together after my attempts at processing. L 65 x 3 min R 28 x 3 min G 12 x 3 min B 23 x 3 min Dual Esprit 150/ASI 178 rig, calibrated and stacked in APP, processed in APP, AP and GIMP. Thanks for looking.

  5. A cute little baby sister for the FC-76DCU has just arrived... at first I thought they’d delivered something else, as the package is so small (compared to my 76) For super wide field, some astrophotography and to pack for holidays (where I want more than binoculars)... a Takahashi FS-60CB

  6. I've been looking through some snaps we took on our trip to Florida last February, which seems a long time ago now . I came across the one below that I took at the Kennedy Space Centre in front of the Shuttle Atlantis exhibition hall. My other half is stood at the bottom of the right hand SRB. This is a BIG piece of hardware The exhibition of the Atlantis shuttle inside the huge hall is very impressive as well - it's turned on it's side and is literally hanging right in in front of you. Highly recommended visit for all space nuts

  7. Kicked off with a wonderful bright ISS pass, very warm out there at 15 C. Got to M3 , nice wide field view and suddenly the Skytrain went whizzing by. Some on line with varying gaps, went by for a few minutes. Very light out there and it didn't improve, our southern sky bright from the town and golf ( now open) illuminated golf range. Gave up on galaxies, so back to binaries and mixed seeing. Some favourites in Coma Berenices and Leo. Finished off with low Porrima, very bright and a simple split, a big change from hardly being able to get it. Some highlights, 35 Coma B.(Σ1687)lovely ra triple, look out for the faint c . Algieba (γ Leonis) simply stunning , especially when you up the power ! 54 Leonis, just a pin sharp marble like secondary. Those marked "contrast " gave wisp ghostly secondaries, worth finding . Careful now and clear skies , Nick.

  9. A Synta 8-24 zoom for my smartphone setup. Same as the Celestron branded zoom but just cheaper. Wanted a zoom with a t thread on the top to use with my TS smartphone holder. The TS holder is really solid as it’s basically an ali plate with an adaptor at one end to attach to the t thread on the eyepiece. Zero flexing. Dead easy to set up the phone as well.

  10. I didn't realise how rich Auriga was with targets and this one - IC 410 tadpole nebula - is a little gem, with the fantastic tadpole structures so vividly on display. Due to the orientation, I only managed 1.5 hours in Ha before it went behind my house. I look forward to grabbing some data in OIII and SII. SW 72ED, ZWO ASI 183GT, 5 min subs.

  11. I'm going through one of those 'I hate all my images' phases, its easy to self destruct your own work sometimes and I get like that from time to time as I'm still trying to get on top of my own personal mental health issues. So to clear my mind I thought I would re process my SHO Rosette data to more of a 'Hubble palette' look. Its still a very noisy image as I didnt push the de noise to much this time to help the details. The noise is definitely not helped by the lack of integration time for the SII and OII wavelengths so will look to get some more data when it comes round again later in the year.

  13. After having a very wet summer I managed to get more data of the Orion Nebula. The Orion nebula is a is a diffuse nebula situated in the Milky Way, in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. It is about 1,344 light-years away, and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. The first image is your LRGB and the 2nd image is IR with G and B filters. ©

  15. Hi! Here is my latest SHO image, it was a pain to acquire the data because this target sets below treeline from my observatory very early but I managed to pull off ~two hours per night. Its almost spring so imaging season is coming to an end soon. I hope I can finish other SHO projects too in the coming weeks before astronomical darkness ends here in Finland. 27x300s SII, 30x300s Ha, 29x300s OIII. 10x120s R/G/B, total exposure time is approx. 8 hours.

  16. Here it is ATM, bearings at one end and continuous 6 inch stainless ball bearing hinge at the other. Depending on the camera focal length it may not need to track continuously, just go in small steps every second or so but can me messed about with in the code. Dave

  18. My first ever HaRGB. I really did fumble my way through the processing which had its fair share of issues, mostly the corners because sadly I cant get rid of the vignetting through my image train (suggestions welcome!) but i can live with it. 5hrs of Ha collected over 4 nights mostly under strong/full moon light. RGB stars collected over two nights but the integration time is very little. Stacked in DSS processed in PS SWHEQ5 Pro, SW80- ED DS Pro, QHY9 mono, Baader filters. I'm hoping to get some OIII to produce a different version but for now I'm happy with this one

  22. I might need a bit of feedback from the forums eyepiece gurus on this one! I felt a bit out my depth trying to compare two eyepieces on camera, so any advice for future eyepiece comparison videos would be greatly appreciated. I used to know a thing or two about eyepieces, but that must have been a while ago....I couldn't remember the right name for eyepiece aberrations etc.

  24. Just ordered my first astro camera - an asi1600 which will be 95% used for solar Ha. Have spent six years as a visual-only guy, but am literally starting at the beginning as an imager, so this feels like a first leap into the deep end of the swimming pool as a kid. Still have to work out which laptop to buy and software to download (scope is 600mm refractor with 70mm double stack filters), so will be some time before I get going - but looking forward to participating more in this forum. Hopefully your guidance can provide me with some buoyancy as I splash around desperately trying to stay afloat.

  25. Relativistic jet motion from M87. Raw data taken from MAST archive from propositions dating from 1999 to 2018. Each set contained 4 frames of which I picked the best one from each year, manually aligning and rotating in photoshop by using difference blending mode and free transforming. Applied false colour and smoothed in SAOImageDS9 Instrument: STIS/NUV-MAMA Filter: MIRNUV

  26. I’d go for the FC 100 _unless_ I viewed regular air travel as a likelihood. In which case I’d go for the FC 76 DCU. But as I’ve said before, if you are not doing much travel then I don’t really see a significant advantage of the FC 100 over the triplet you already have, other than weight. Unless you desire ownership of a Tak - which is a symptom of that well know malady called Takitis

  27. Today I reprocessed some data of the Flying Dragon Nebula from Sept. last. My original contained 7 hours of SII but this time around I have left that out completely - I like the result with just Ha & RGB (Total 16½ hours).

  30. As a regular reader of the latest publications broadcast on the ArXiv astrophysics list, I was especially interested in several of today’s papers, which I suspect are ground-breaking: The Existential Threat of Future Exoplanet Discoveries Pandemic Dark Matter Using Artificial Intelligence to Shed Light on the Star of Biscuits: The Jaffa Cake Science Spoofs, Physics Pranks and Astronomical Antics The first is published in that highly cited journal, Acta Prima Aprilia There are quite a few other classics listed (including one referring to Taylor Swift songs)

  32. It's been months since I've been able to visit my local dark site. Thanks to the reduction in lockdown restrictions, an opportunity came up last night to go which I jumped at! Arriving onsite around 8pm with the sky still fairly bright, I was able to take my time setting up, carefully collimating the 10" dob and aligning the finders. I started off observing the Nova V1405 in Cassiopeia. I've viewed the Nova many times over the past 10 days so it felt like familiar ground. M52 really popped under the darker skies. I popped the 10mm Delos in for a closer look. This really brought it to life with many more stars visible when compared to what I can see from home. Winter observing has been a bit of write off with few opportunities so it was particularly nice to spend some time with M42. An OIII giving an increased sense of texture and depth to the Nebula. At this point, I spotted the ISS rising and decided to play chase the space station! Using the unfiltered Delos, I got a few fleeting glimpses of the ISS in the eyepiece to start with. Repositioning, I managed to keep it fairly well centered for what felt about 10 seconds but, in reality, was probably more like 2 seconds! It was enough to get a real sense of the solar arrays. Pretty good going at 120x and a 0.6 degree TFOV! Earlier this year, I was lucky enough to get a Docter/Noblex 12.5mm eyepiece. I've been really looking forward to trying at the dark site. M51 was the target of choice for the Docter. The view was superb, beautiful spiral arms could be seen. Some of the best views of M51 I've had. The Leo triplet just fit into the FOV. Concentrating on NGC 3628, I felt like I could pick out the bar through the center of it. Virgo had now risen above the trees so, after a brief visit to M53, the galaxy hunt continued. Starting off at Rho Vir, I picked up NGC 4596 and then onto the Siamese Twins. I love this pair of galaxies which form something like a butterfly shape. From the twins to M58 and then Virgo A/M87. 3 more small galaxies filled the FOV of view around one side of M87. Virgo is simply bursting with galaxies. I have no idea how many I missed journeying through Virgo. The crown jewels of Virgo, Markarian's Chain was my next stop. Still using the Docter, I moved slowly down from M84/M86/NGC4388 to the Eyes Galaxies to NGC4461/NGC4458 and then NGC4473/NGC4477. I then used the APM UFF 30mm and APM HDC 20mm to get the complete chain into the FOV. Leaving the chain I passed NGC4459 and then enjoyed views of 3 more Messier galaxies (M98, M99 and M100). The Moon was now starting to rise so I decided to try for one of my galaxies goals! I'd never been able to observe the Antennae galaxies in Corvus before. With some careful star hopping and study of SkySafari I landed in the correct location. The Docter was again deployed. With averted vision, I could just detect the faint grey pair of galaxies. It was by no means I spectacular view but I was really chuffed to finally see them. A revisit will be required without the Moon starting to peak out to properly enjoy this pair. My attention moved to some brighter targets to finish the session. The Ghost of Jupiter planetary nebula was an easy find. With an OIII it had a distinctly mottled look to it and just invited further study. A quick observation of M1 was unremarkable so I finished up with the Eskimo nebula. I always enjoy this best without a filter. I packed up and headed home a little before midnight. On the way home a group of eight to ten full sized deer crossed the road in front of me. A nice little bonus to end a lovely night on.

  34. Looks like you were shipped a good one ! Looking forward to the results from a clear day. One thing I have noticed in all my calcium experience over the last 10 years is that it almost always works best in the "worst" quality of telescopes. Name brand doesnt mean much to a calcium filter, so stellarvue , APM and astrophysics are just bumper stickers. In fact, a scope with the most violet fringe you see on the moon is the best choice. Typically a generic; $100.00 meade 90mm x 800mm standard plastic cell achromat will outperform just about any $1000.00 telescope out there at this wavelength. Have fun discovering your new skill ,

  38. You wouldn't gain much by unscrewing the DC dew shield, just 3 inches. The FC100D series only have a 95 mm tube diameter because the beautiful lens cell is housed entirely within the dewshield. The DC is a seriously sweet, lightweight refractor.

  39. I found my Tak better than the Astrotech 106mm triplet I had before it for planetary detail, and I had considered that an excellent scope before having the Tak. Worth comparing both if you don’t have to sell the other first. 76 vs 100 is a tricky one, they are both lovely scopes. For me the 100 has enough of a resolution benefit to be worth making the effort to take away with me, but 76 will give that bit wider fields of view if that is most important to you, as well as being a bit more portable.

  45. The Fish Head Nebula. My first proper image with the new camera after my 60Da died. I had a few teething problems due a bug in APT with Flats but got that resolved with the help of some very clever folk from around these parts. I think I'm going to like this camera for a while until I finally decide to go Mono. I'm going to add more to this (Clouds came tonight!) and I think I'll use this as the basis of a mosaic and go for the heart.
