  1. Blast from the past. 2 years ago, when I got the Samyang 135mm f2 lens, I couldn't wait for the winter to come so I can shoot Orion widefield. Well I did shoot it but I forgot about the data and 2 days ago when I decided to redo some of my 135mm work I stumbled upon this untouched data and I went to work Details and full resolution on my astrobin account https://www.astrobin.com/5i2906/?nc=user Emil

  2. I'm slightly nervous about posting this but I'm amongst friends so here goes. I've been using my Tak 100 refractor to observe double stars this evening but I noticed that the sky transparency was quite good so I've also been challenging the scope and myself to see how many galaxies I can spot. I thought I was doing well in finding 11 in Leo, and quite a few in Coma Berenices, Virgo and Canes Venatici. The brighter ones were looking really quite contrasty for a small aperture scope. I was going to have a look at the Markarian's Chain of galaxies on the Virgo / Coma B border but m

  3. Another from the easter week-end. This is the old 8" LX200 on its wedge again, EOS700D, 53 X 180s ISO800. Strangely my go to stacker APP made a hash of this for some reason that I dont understand, so I tried stacking in PI using the WBPP script and it did a great job. Post processing also in PI C&C welcome.

  5. Monday 12 April 2021: let the bells ring! By 9am I was at the Enterprise lot in Peckham, south London, and by 10am I was on the road to Dartmoor for my first dark skies expedition. I bought my first telescope a few months ago – a little ST80, after lots of great advice on this forum – but hadn't used it outside of Bortle-9 skies, where I found it to be ... fun, but not mind-blowing. So I was looking forward to seeing whether @ScouseSpaceCadet was correct: that in dark skies, away from the blinding wall of the council estate LEDs, said mind would indeed be blown even by what seems to be th

  6. I'm calling collecting data enough for this season. 5 years ago I put the DSLR for the first time at the back of a telescope and I took my first shots. Some of them were aimed at M81 and M82. For the next 5 years I collected more data with various scopes, cameras, carried by many mounts. The newest one is still fresh, I finished collecting RGB and Ha data for it this morning so more processing versions will come. I used for it also some Lum data I shot in 2019 with the large 200mm newton from home (for highlights only), Lum data I collected last year during the emergency state w

  8. NGC 4449 is a dwarf galaxy located in Canes Venatici, 20,000 light years across and c12.5 million light years from Earth. Its structure is similar to the Large Magellanic Cloud (LMC), the satellite galaxy to our Milky Way. Evidence for a very high rate of star formation is indicated by the presence of many young blue stars and pinkish star forming regions. It was the first dwarf galaxy to have an associated tidal stream identified which is the product of violent interactions with another satellite dwarf galaxy, NGC 4449B. The faint remnants of NGC4449B appear as a dim trail of stars and

  9. This season, I really wanted to get back into stargazing. I’d hardly done any for some years. I had various excuses for the lack of observing. But this season, I was going to be back! Well, the weather was dire for the first month or so. But over the season, the sessions gradually racked up. And I was wondering whether to skip tonight's session - I was feeling cold and tired. But there was no such defeatist talk over in the Astro Lounge: “Tonight is the night”, declared mdstuart. “Transparent skies over the uk tonight and no moon”. Well that picked me up. And anyway, get a good sessi

  10. Yes I was shocked too. But there it was in the Sunday Papers. Pretty firm rumours that Los Alamos National Lab has put in a hostile bid for Takahashi. The report speculated that what they actually want to do is an IP strip, as they believe said company has discovered a new fundamental force which explains why their scopes don’t conform to the known laws of physics regarding option resolution, light grasp and magnifications (x 500 mag and more has recently been claimed by an undercover researcher in Lancashire, using an FC 100). when the potential demise of the Takahasi parent company beca

  11. It's that time of year where we're seeing this pop up a lot. I think this will be the last broadband image until later in the year. Just 19 x 300s Lum and 6 x 300s each of R, G and B on the last clear night recently. Taken with my RedCat and an Atik 460EX. The lack of data is showing at full resolution (e.g. M86) but I've left it anyway. I'm loving M88 and some of the smaller NGC galaxies. Captured with Voyager, calibrated & stacked in APP and processed in PixInsight. Thanks for looking! @Rob63 showed a similar markup to the one below in another thread

  12. For the first time in 20 years, I finally have an observatory again, a pulsar 2.2 dome. This is also the first time I have used a dome, previously having had a roll of roof shed. I moved last December to a house with a bigger garden and top of my list was an observatory as our previous residence's garden was so small, an observatory would have swamped the place. So hopefully, I can now be more productive and here is an effort from my new abode. Total integration time was around 9 hours and taken though a SW Esprit 150. Adrian

  14. Ever since I first saw NGC 3718 I've wanted to image it at some point so I decided to dedicate some precious clear skies to it recently. This was taken over three nights where the moon was rising well past midnight so it's effect varied as the early hours came round. Using the StellaLyra 6" RC and ASI533, it was taken at native focal ratio, so a very pedestrian F9 Original image was ~0.57"PP, so this was IntegerResampled in PixInsight (2x) before starting processing. In total, 333 x 120s (~11 hours) of subs were integrated. Captured with Voyager, stacked & calibrated in A

  15. The first telescope I used after work yesterday was a Daystar SS60 H-Alpha Solar Scope. This arrived last week and so far I've really enjoyed it as my first Ha scope. I've seen several proms and some impressive surface detail. Sitting in the warm spring sun, I didn't appreciate quite how cold the night would get. A few hours later, I was setting up my 10" dob at my local dark site. I often have fellow observers when with me at this site but on this occasion I was alone which felt a little eerie. The dob was quickly collimated and the finders aligned ready for action. M52 and the Nova is Cassi

  16. As a dummy run for my attempt to image the 3C 273 jet I thought I would have a try for the somewhat easier plasma jet emanating from the supermassive black hole at the centre of M87. Here is 78 minutes of Lum data, captured with the Esprit 150/ASI 178 rig. I am 99% certain it is present on the stacked image, by comparing the orientation of the brighter pixels at about 11 o'clock with library images. I was a little uncertain as some of the brighter stars appear to have an artefact in about the same place. Interestingly it actually shows a tiny bit of structural data on a single 3 min sub

  18. Landscape astrophotography is something I’m interested in getting into more. There were some faint Aurora recently so I decided to give it a go. This is a foreground stack of 3x180sec on foreground and 1x30sec for sky, Nikon D600 and Samyang 14mm. A half critical eye will show my blending needs work and of course the sky is quite noisy since it’s only one frame at fairly high ISO. Hopefully it’s still semi pleasing to the eye

  19. Clear night #7 of the month, what to do? My wife Sarah fancied a brief observing session – a few globs would do! - before leaving it to me to carry on into the wee hours. Mindful of my wife’s limited time and taking into account my navigation skills - I once got lost going to the local garage picking up some milk for visitors (“Where is he?”) - I placed my faith in the goto mount. I’ve grown fond of the HEQ5 since it complimented me last time out. “Alignment may be inaccurate”, it had commented. A few words of encouragement can mean a lot from our electronic friends.

Many thanks to @tooth_dr for all his amazing help on that. 96x 1min Lum 59x 1min Red 57x 1min Green 52x 1min Blue 4.4 hours.

  26. Back in October I found this faint object by surfing in Taurus on Aladin Sky Atlas and did not recognize it until I started processing and suddenly realized I was looking at the Baby Eagle. Seeing was not the best and processing was quite challenging. I have now had the EZ star reduction script in PI to have a go at it. It really helped to suppress the star field to a level that lets the faint nebulosity shine. Data gathered with a RASA 8 and ASI2600MC, 73 x 4 min at gain 100. I like they way this combo can bring out colour and light in objects that often look rather dull.

I had this same combination some years ago, and had some wonderful views from dark sites, normally whilst camping down in Dorset. It gives a 5 degree field of view at x16 with a 6.2mm exit pupil. I remember the field being very flat, stars sharp to the edges; no difference in focus point between centre and edges. Filtered views of the Veil and NAN with an OIII filter were wonderful. Fast forward a few years and I’m on my third, and best Genesis. Thi

  31. I have been moaning on and on about the coma in the old LX200 GPS and how it is not fixed by the meade 4000 F 6.3 Reducer. Then I read post on here 9sorry cant find it now) which suggested that modern refractor FF / FR 's may work better than the specific Meade FF / FR . So I stuck the SW 80 ED 0.85 FF / FR on the Big Blue Trash Can last night and thought "in for a penny...." So bolted the ASI2600mc on and sent it off to find the Needle. Now its giving me 1700mm FL (although plate solve says 1900), and with the 2600 mc that comes to a image scale of around 0.4". So I binned it 2 X 2. I got thi

Temperature was just below freezing, and the wind chill made it feel like -5 deg C. Started out with the M52 open cluster and the Nova. Cold and breezy. Local light pollution M51 (Whirlpool) - Hints of structure with averted vision. M101 - Very faint, needed averted vision and some dob-wobbling to find it.

However, I have my first Covid jab tomorrow, so thought I had better make the most of the first night, and thought I'd try for a longer session than normal. After a week of quick sessions with the new ST80, it was nice to go back to the 8" dob. All the posts about seeing Sirius' pup inspired me to have a shot. I moved a table to the northern side of the garden and set the dob up on top, so that I could get a view of Sirius. Shouldn't have bothered though - the seeing was pretty bad and disco-ball Sirius was jumping all around the f

  38. Similar to last year, April has offered up more clear nights than we've been used to recently. Astro darkness is around 4 hours right now. This was captured over four nights with some fairly ruthless removal of subs where star shape or quality was poor. A second project for my StellaLyra RC6, with M51 being a brighter target than my first project (NGC 3718). I left it at F9, without a reducer. In the end 9.5 hours was integrated with 285 x 120s subs. Check out IC 4278 (just above NGC 5195) and IC 4278 (just above and to the right of NGC 5195). Very faint but clearly visible.

  42. Ngc 2175 is a star cluster, associated with an emission nebula in the constellation Orion. The nebula goes by the popular name Monkey Head nebula. There is some debate whether the nebula has its own ngc number (ngc 2174) or whether this number is a double in the catalogue, so that the star cluster actually has two ngc numbers. The nebula and cluster are about 6 400 lightyears distant. The nebula has an angular width of about 40 arc minutes. This means that it's a big monkey, with a skull that is about 75 light years across. The data for this image was collected in February of this ye

After getting engrossed in an old film with my other half after supper, I found that Sirius had got rather low to be worth observing so I had a quick look at Zeta Cancri (Tegmine) and then Nova v1405 Cas (which seems slightly dimmer but still around magnitude 8 ) and then had a look at the galaxies Messier 81 and 82. These seemed quite bright and well defined so I decided to put the 12 inch dob out, have a cuppa, and then

My first target was the Rosette nebula with my OIII filter. I cannot describe my excitement when I saw it. The size of it! It did not fit in my 32mm EP (50 FOV); clear nebulosity looking like a donut with darker middle. I was mesmerised and I spent a good 20min observing and taking everything in. My next one was NGC2359. Very faint nebulosity with the filter on, i think coming from the Rosette it felt a bit disappointing.

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.

Given my location and the first quarter moon I am not too displeased with this one. As always, it could do with a little more data.... Taken with a Stella Lyra RC8 reduced down to F6 and an ASI1600MM. Constructive criticism and comment welcome as ever.
