  2. Postie has been busy. That's a cover for my new tablet by the way, with the book to get it free postage! As recommended by Scousespacecadet to fit in the pocket - crumbs he must have small pockets - it fits easily in a shirt pocket! It will be interesting to try the ES against the Starguider I got recently - if we ever get clear skies. (OK I know it was clear last Thursday, but I was so tired from work I fell asleep on the sofa after dinner) David

  3. M108 is a spiral galaxy 46 million light years distant in Ursa Major. It is inclined at 75 degrees from the viewers perspective, so the spiral structure is hidden from view. Visually it appears as a relatively small object (11.1’ x 4.6’) with an apparent magnitude of 10.7. Its core is estimated to contain a supermassive black hole with an estimated mass of 24 million solar masses. I was pleased to capture quite a bit of detail on the galaxy including the Ha emission areas. The background also contains many small, more distant, galaxies. The LRGB image below was taken with my Esprit

  8. Hey everyone! Well, Saturday night ended up clearing up for me out of nowhere - it was 11:30pm and I went outside with my torch to double check that my pet chickens were locked away for the night when I noticed after my eyes had adjusted that it was clear out! - a quick check of the weather confirmed that this should be the case for the next few hours at least... After a bit of a dry spell in terms of clear sky opportunities I was ready to take any opportunity I could, I quickly got everything out and cooling down while I picked a target. I'd settled on m81 & m82, well posit

  10. A little over a year ago, on the day I turned 58, I saw that a scope I had been watching on the Dutch te-les-koop.nl website had dropped in price to a mere EUR 165. I decided to treat myself to an extra OTA, because having just one Cat (the venerable C8, of 25 years of age) didn't feel right . The black cat needed company. More seriously, a 6" F/5 scope, with its 762 mm focal length, relatively fast optics, and little coma would sit nicely between the 8" F/10 C8 at 2030mm focal length, and the APM 80 mm F/6 triplet at 480mm (or 384 mm with 0.8x reducer). The C8 is my best planetary imaging sc

  12. Hi everyone The steady atmosphere worsened as the night ground on. The EKOS scheduler finally called it quits around the time Cor Caroli all but disappeared behind the haze. This is a noisy example of what an old DSLR can do with cheepo beginner's hardware. The highlight of the session though should go to the software. EKOS' SEP-multistar kept the guiding sane throughout. Only one frame was dropped -immediately after the unattended flip- in the early hours. Thanks for looking and do post if you've had a go at this. 700d on gso203 4h @ ISO800

  14. Finally got round to sorting out the other two cases... Firstly a grab and go case (Plossls, Orthos, Barlow & diagonal) for quick short sessions and just keeping things simple Then a small case to keep the binoviewer, Hyperion zooms, Meade 16mm pair, 1.6x Barlow and erecting prism, when not living on the Mak 127.

  18. This evening I took some photos of the moon with my 90mm refractor and Canon EOS750D. The first one is at prime focus and the second two are with an eyepiece projection attachment (Plossl 9.7mm). I found it very difficult to focus using the back screen on the camera in 'live view' mode as the wobble on the mount was quite bad whenever I adjusted the focusing knob. So my hand was causing so much motion that I couldn't really tell if it was in focus until I'd made each adjustment and waited for the oscillations to die down. I had the same problem with the shutter release (so I used a 10sec

  19. A nice clear evening so took the 4” refractor out for a look at Mars. Seeing was initially very poor at twilight but got better by 19:15GMT so went straight to x384 to get a tiny disk that clearly had a phase and a bright preceding limb (mist/haze) but I could not detect any dark surface markings. I think that’s it for me and Mars now this time around - roll on 2022 But first let’s see what Jupiter and Saturn have to offer in the Autumn ..............

  21. After I bought my first RASA 8 less tha a year ago I have become a great fan of that scope, as you can see from my Astrobin. So tonight I have the "old" RASA 8 ready in Obsy 3 (the decicated obsy I built for it) and in Obsy 1 my Esprits were just put in their boxes to give place for first light of my new second RASA 8. The plan is that both will be aiming at IFN near M81 - but the clouds are yet not co-operating......

  22. Bought a set of 3nm narrowband filters - Antlia - a Chinese company - very kean pricing v's the incumbant premium brands, based on just this one image I am impressed with the result s as the subs for this image were all taken over three sessions of the weekend 26-28th February so full moon conditions. Camera ASI1600MM - gain200 / -20degC 36 X 300s for each filter, Ha / Oiii / Sii - 9hrs total subs Stacked in APP, processed Pixinsight and PS CC Two colour pallettes , first is a straight forward Hubble SHO and the second a blend of various pixel math ratios and equations.

  25. Glad to say the observatory is up and running again . OK, it's now roofless, but at least I can observe in the space within the shelter of the walls which also keep out extraneous lights. I've cleared the debris (which can be seen lay against the far wall) and swept it out this morning and put the Vixen Super Polaris (in altaz mode) back in situ. What's more its sunny and forecast to be clear well into the evening. Happy days . When I'm not observing, I only have to move the mount into the other side of the garage, which still has a roof! The observatory will remain roofles

  27. No. Any aberration from the objective already exists by the time it gets to the eyepiece and so the eyepiece will show that aberration, plus any aberrations from the eyepiece itself. The only real exception to this is field curvature, where the curvature from a particular eyepiece may counteract the curvature from the telescope.

  28. There are apps out the to do this. Often Android phones have good Pro modes on them but I checked and it seems the 4a doesn’t. I use an app called ProCam 8 which is only for iOS, so you could try Nightcap which lots of people rate. I saw an app called GCam suggested but it didn’t seem to get good reviews so I’ve no idea if it’s any good. Ha imaging is tricky but certainly achievable with a phone. I’ve attached a couple that I have done through various scopes, a Quark and a PST mod.

  29. This thread is for adding in your observations of RING GALAXIES. Here is my somewhat basic understanding of ring galaxies. Ring Galaxies – a galaxy with a ring (torus like structure) of stars. If only it was that simple. There seems to be various ways that a ring may form. About 50% of spirals have rings or partial rings and are most common in barred galaxies. The bar of stars sets up some sort of resonance pattern in the orbiting stars. Three principle current theories of ring formation. If the galaxy has a bar that becomes unstable as the galaxy rotates then the stars in

  31. Using a small telescope - a Sky-Watcher Skyhawk 1145p, EQ1 plus small cheap & bodged motor drive in Bortle 8-ish sky’s. Or so the data says but I’m becoming convinced it’s more like a 7. I haven’t been a member long and I’m new to all of this but thought I’d share this. It’s also the first object I’ve found that I couldn’t see with the naked eye and I spent around 40 mins searching before I found anything. Should have looked at Andromeda too when we had the chance but it’s now gone over the back of our house. For my daughter, it’s was after midnight and she was long in bed, I e

  33. Managed this last week over three nights. Very late in the season, there's a tree in my neighbour's garden on my western boundary which is just in the wrong place, so I was getting only a few hours a night before I lost the target in branches, so I binned everything to get more signal. Anyway, excuses over: 40 cm f3.6 scope, QSI6120 camera 100 minutes L in 5 minute subs bin 2 18 minutes each RGB in 2 minute subs bin 3 60 minutes each Ha and O111 in 10 minute subs bin 2 I'm so happy to have something to post, cloud and rain are so boring.

  35. I'm hoping to get an EAF as my next astro purchase. I have been a naughty boy this year on spending so I'll have to control urge for a while longer! They certainly don't come up very often in the classifieds so there must be a lot of happy users. As a fare paying fan of APT I keep on top of developments and have been watching the focuser routine evolve. Good to know it's testing ok in the wild Goto++ was my first experience of solve and sync and it blew me away! And now with ASTAP set as my default solver it just gets better.

  38. The Baader Steeltrack BDS (SC/HD) for the Mewlon180c has arrived. I hope it solves the big problem of precision focusing at high magnifications and in critical situations (light mounts, excessive load, bad seeing, ...) For those interested, you need the BDS SC / HD model with the adapter that converts the Takahashi visual back to SC: Takahashi Code: TK-TSC00100. To further shorten the path, the Baader prism is fitted with its 2" nose code BA2408150.

  41. Hi everyone, My first post here - thought I'd join up and hope you might enjoy seeing the odd Southern hemisphere target. In 1969 Rufus Thomas wrote - "You flap your arms and your feet start kicking Then you know you doin' the funky chicken". Which is possibly what the guys at the AAO were doing when they named the 'Running Chicken' nebula! I've presented NB versions of this timeless classic target here with and without stars. 6 Hrs HA x 900 sec 2 Hrs O3 x 900 sec 3 Hrs S2 x 900 Sec Taken via Stellarmate (while sleeping!) from my light polluted Bortle 6 suburban B

  44. I started that thread about my struggles with Ritchey Cretien collimation, which vlaiv referred to earlier. I would point out that one significant positive thing about them is that they hold their collimation extremely well, so I’m not sure where you got the idea that they need constant collimation. Despite my trials and tribulations, I have now mastered RC collimation, which is easy once you get the hang of it! I take it on and off the mount frequently when swapping with other scopes, and it never needs re-collimation.

  45. It was a full moon and a spooky night when I went hunting for ghosts in Cassiopeia!! I was hunting with my Optolong L-eNhance filter and SW200P reflector to give me this chance beginning of March. A tricky target but I'm glad to say, 'I got one'!!! I hope you appreciate my efforts.

  46. Looking back at my notes I observed this back in January at x281 mag. I managed a very tight split, so tight I’ve noted it at about 80% sure of success. The secondary was at 11 o’clock and could only be glimpsed in brief periods of good seeing amongst the diffraction spikes of the primary......so I think your observations match mine really........and I’m also not 100% I can mark it off, we could start a club!!

  47. First up is an old friend, Arp 148 in UMa. Not the easiest of targets to view. Its to the right of centre in the wide shot. It is a classic example of a galaxy doing a direct hit on another one. This pair are known as Mayall's object and lie about 500 million lyrs away. The offending galaxy has gone through the centre and is now heading out the other side. The shock wave creating the ring. Search out Hubble's image for this pair. Arp 336 in UMa - NGC 2685 takes us to the nightmare of galaxy designations - it is (R) SBO^ / pec (Sy 2) = outside ring, barred lenticular, messe
