    So after any years of observing you think you must have seen the best by now. Last night blew me away. FIVE yes FIVE galaxies in the FOV that are much easier than the Stephens Quintet. Why oh why is this not as famous. The Webb Society magazine was my inspiration. Not expecting much from my home location I pointed the scope and BANG...a large fuzzy mess...the NGC 708 group in Andromeda. Here is a pic off the internet. I could see the Y shaped group of five galaxies. NGC 703 / 704 and 708 are immediately visible but 705 is tougher needing patience and high power. 709 was also just possible with averted vision. What is more 703 has an embedded star that is only possible with AV. Looks like a supernova but is not of course. So come on then, give this a go.,,,,John will have it with his 12 inch I am sure as its easier than that Quintet. Enjoy Mark

    Next time anyone is going to Winscar please let me know, I have been checking the events thread that soupy set up, but no luck yet. Have just sold my 8" DOB on eBay but still have my refractor. I am saving up for an upgrade scope but not decided which yet , need to keep it secret, not the scope but the cost from my missus lol.

    The other night's sky gave an opportunity that couldn't be passed up, with the transparency clearing the longer I viewed...until I quit at 4am. After studying Pegasus for a few hours the bright stars of Orion emerged, first time viewing this favorite object in a while, and I must say the UHC gave up a unique view of the complex area. This UHC shows an extent of nebulosity that is quite amazing... much more than the OIII under dark skies and M42 was no exception. I must first say that I like viewing this object with no filter as more defined edges in the wings etc show, I can easily see the lower loop and the "hook" in the wing, with M43 showing distinctly. BUT, with the UHC the area under the wings were almost completely filled! draping down to almost close the lower loop a cigar shaped "hole" was all that was left in the loop and many features of M42 were smeared out by this extra nebulosity. This view was striking to say the least... Some extra patches around M42, M43 were observed. I tried viewing with and without the UHC, same for the OIII... what will be nice is viewing with a filter slide to really accentuate the differences. For this type of object the 100 deg EP's seem made for the job, with no defined borders (FS), well you can see it if you try. The UHC takes mag very well, allowing views of the core in the 200x range, exposing it's swirling green marble like texture... All in all a VG night!

    I made a late call to set up going at 9:20pm. It was partly cloudy but forecasts had clear skies coming. I may look stupid (but it is dark and who is going to see me?) but I have really benefited from using an eyepatch on my right eye while observing. I can view so much more comfortably and for longer. Andromeda M31/M32/M110 I started with the Andromeda galaxy and spent about an hour and a half viewing it and its surrounding galaxies. I used a 20mm Nagler T5 giving 91x magnification for most of the viewing, though I did try a 15mm at 122x for a while but this didn’t really add anything. The core appeared as a bright blob, similar in size to M32. There was a stellar like point at the centre. Several stars were superimposed on top of the bright core which appeared a bluish grey to my eyes tonight. I noted faint haze out to HIP 3447 and the inner dust lane seemed to extend out to here. It extended the other way and curved around the inner bright core somewhere between M32 and HIP 3293. A longer outer dust lane was seen reaching out past HIP 3293. I also thought I saw some form of structure between M32 and the star HIP 3333 but this could be my imagination. It was a very faint haze with a dark line, not very big. I’m not going to call this as definite but will be looking out in this area in the future. Below the star HIP 3293 I noted a line of three faint stars. Beyond this was a group of stars looking like a miniature version of the constellation Leo. Nesting between these two groups was a fuzzy patch seen with averted vision. It was NGC 206. An 8mm giving 230x confirmed the presence of a fuzzy patch. No detail was seen but it was nice to know you can see a star cluster in another galaxy! M32 appeared as a featureless blob but I detected three stages to it. A bright stellar like point, a bright haze around this blending into a dull faint fuzz. As the night went on I came back to the system of three galaxies. Using a higher power on M110 I could see that there was a core, an elongated haze shape to the galaxy and a couple of faint stars within the haze. Nothing structure wise or definite shape was seen however. Pacman Nebula I have wanted to see this nebula for a while now. I have tried before in my 12” telescope and not had any success. However tonight I finally saw it. Using a 20mm Nagler T5 with UHC filter I moved to the area of the nebula. I noted the Y shaped star formation pointing to a star above, telling me I was in the correct area. Slowly but surely white fuzziness appeared around the star. A 24mm with OIII filter didn’t do much, nor did the 24mm with UHC so I kept with the 20mm/UHC combo. After a few minutes a definite pacman shape with mouth appeared. It wasn’t very bright and hard to make out from the background. Several faint stars appeared in the vicinity. Clouds rolled in for about an hour cutting my observation short. When I came back out just after midnight I decided to try different targets that would be disappearing behind trees soon. I will return to this nebula again and was really excited to have finally seen it. I also tried for the California Nebula. Wouldn’t say I saw much but definite hints of nebulosity in the area. Mirach At about 12:45am I stopped off at Mirach. The star was a bright yellow colour. I detected a faint star close to it, somewhere just below it and also the galaxy Ghost of Mirach to the north was easy to spot. Triangulum M33 I found the galaxy when it was high in the sky, near the zenith. The streetlights had gone off so it must have been about 1am. I used a 20mm Nagler T5 giving 91x magnification. A 24mm, giving 76x magnification made it almost disappear apart from a small part of the bright core. Switching back to the 20mm, I noted first the bright core and a rather faint haze around it. Below was a star with a small fuzzy blob next to it looking like a galaxy in its own right. Could I have detected NGC 604? Near the core I noted several faint stars around the top. Later I started to see darker patches with averted vision suggesting structure. However, I am not certain and it may just be my eyes trying to join up the faint stars ala canals on Mars. It was hard to determine a shape. It seemed to go off in two different directions, with averted vision showing that there was a part to the top left of the core. I couldn’t get a definite shape just a rough idea of the general area of fuzziness, as shown by this sketch. This one is tough! I could have changed the shape several times, new parts seemed to be appearing all the time. Definitely an irregular galaxy shape in the fuzz somewhere! M74 After viewing Triangulum galaxy for a while and it moving ever closer to a tree, I star hoped from Aries across to Eta Psc. I searched for M74 and found it, though it was very faint tonight and averted vision was needed to find it. It barely stood out from the background. No detail was seen. Star Clusters While waiting for M42 to rise high enough I visited a few star clusters. The Pleiades, Hyades, M36 and M38 in Auriga and the area around Mirphak in Perseus. Nothing special to note but lots of stars on display. I eventually made it up to the Double Cluster in Perseus which was high in the sky by now and took a quick look. M42 It was getting near to 2am and I could see cloud coming in from the north east. Even though it was low down I stuck my 20mm back into the eyepiece holder and took a look at the Orion nebula. It was large, the fish mouth by the trapezium of stars was on display. By this appeared a U-shaped wing. The nebula was rounded and larger than I remember ever seeing it. There was also nebulosity by some stars just above this nebula. With the clouds getting closer I decided to pack up after a couple of minutes viewing of the nebula. A good night and new details seen in Andromeda and M33. Really happy. John

    The best thing is to try and make sure that no lights show outside the vehicle at all if possible. Things like the courtesy lights can be turned off or have some opaque tape put over them. Even red lights, if there are too many of them, can affect dark adaptation. At the last star party I went to there were quite a few red lights that were well intended but just too bright about. Sorry if that sounds picky but if the skies are dark there the visual observers hunting the deep sky objects will want to stay as dark adapted as possible.

    Hey, Had another hack at these two since I wasn't really happy imaging anything else until I was satisfied with these DSO's first. M45: 25 x 75s + 10 dark frames http://www.astrobin.com/219324/ M42: 10 x 90s + 10 dark frames http://www.astrobin.com/219323/ All in all i'm actually really pleased as they're a lot better than the last attempts. I'm not sure if theres any more data in the M45, I thought there would be a lot more coming out in that one but it could just be my PS skill. Ali

    So the forecast was clear, good/very good seeing. I compiled a list of objects I'd like to have a look at and made note of what page they were on in triatlas. We got to wembury beach, it seemed clear enough, milky way right over our heads. But for some reason, I couldn't for the life of me find the right stars to guide me to M16, so after a few minutes of trying to figure out where is was I gave up on that and moved on. My next target, one that's been on my list for a while was the Veil, in attempting to find this I learned to make out the constellation cygnus, whereas I couldn't before. But finding myself at 52 cyg, I couldn't see any nebulosity until I put my OIII filter in place, but even when it was there, the nebula was only just noticable as a wispy line running down the EP, I mght have seen the other part of the veil (the bit that looks like a face) as well, but I couldn't wear my glasses so who knows . My exit pupil was 3.5 which seemed reasonable, didn't quite expect it to be that hard to see. The next target I wanted to attempt was the blinking planetary, which is apparently called so as it appears to "blink" in and out of sight. I thought that was sorta weird since the nebula has a very high surface brightness. But I never go to find out whether this was true as I couldn't make out the stars I was seeing in the finderscope once I had it pointed at I and K cyg so I gave up on even finding it, perhaps another night I'll try again. Next I moved on to the andromeda galaxy, I had fairly high hopes for this since I had seen it in my bins from home where the LP is stronger. But even at wembury I could only make out the core. My last target was the couble cluster, it did look much better in my scope than in my bins, but my attention was drawn to something I hadn't noticed before: some stars appeared sharper than others! There were two stars in one of the clusters that seemed very sharp and small, whereas most of the other ones looked a little smudgey. Perhaps this is to dow tih the brightness of the stars? Either way, fairly happy with the session, although it lead me to realise my skies aren't quite as dark as I thought previously p.s. I realised I get strangely dizzy under dark skies and lose my balance a little. Someone watching me observe might think I was tipsy at times. it's probably because I can't see the floor properly. ~pip

    Had a great night on the 9th October just outside Horncastle in Lincolnshire which was clear all night. Not a single dropped sub so managed ~6 hours on IC1396. Although towards the end the subs were starting to get a bit lighter as they were entering the "murk" and getting a bit too low in the sky. The Garnet Star giving me a bit of grief but otherwise quite happy. My last attempt on this area was a waste, couldn't see anything. The problem with this area is there are so many stars...it is just full of them. However the benefit of taking 75 subs is that I didn't have to perform any noise reduction at all. It was all fairly quick to process. Might spend some more time on it in future just to tease out more, the dark areas are really dark (black clipped I think). Acquisition details: Baader Modified Canon 6D @ ISO1600 Canon 500mm f/4 L IS @ f/4 with IDAS LPS-D1 filter. 75x5 minute subs Avalon Instruments M-Zero Thanks for looking...

    Why dress our vans up like Xmas trees ? My van has 4 interior lights. I use just the one at the far end shielded so that there is enough light to move around safely in the van but no more. A blind + curtains stops any light spilling out of the end of the van and thats it. I can understand if families are in vans while we are astronomising that they need some light. But otherwise we can do without for a few hours surely ?

    I posted these on CN last night & thought I'd post them here on SGL as well: there are 2 or 3 other images on about the same level as these but I chose these 2 to create a couple of our "Somersaulting Saturns" for the website... Check out the website http://momilika.net/ & click on the Saturn icon & then go to the "Latest Saturns" link to see a bit more info but SGL should accept the .pngs at full scale...if not they'll definitely be full-size on our website! ps: The top image is from the ASI174MM & the bottom from the ASI224MC!

    If it was not in stock, and they did not contact you about this, then they have breached their own terms and conditions: "‘In Stock’ orders are shipped the same working day if we receive the order before 2pm. You will be notified at the time of order by email (online orders) or by telephone (mail orders) if your item is backordered. ‘Back Orders’- If your item is not in stock within 5 working days of placing your order we will back order the stock for you and email you to confirm this status. Back-ordered goods that remain fully paid are placed on a priority over unpaid for orders. ‘Out of Stock’ Items - If your item is out of stock, we will contact you as soon as possible and offer the option to cancel your order or wait for the item to come in." I wonder if this thread has prompted them to email you tonight... It's not nice to pick fault with a new company, but if their customer service is [word removed] poor then that is a pretty poor show. Maybe they'll get their act together and become a market leader. Watch this space. James

    that's looking good dude, as above have said all have to start somewhere an practice always helps in long run, just to say that when I use the 6" newt i can get you a whole disc shot, your 8" should produce a whole disc as same FL but better the devil you know, not sure if you have a white light filter for that.

    Nice report. I find that UHC filters are best for some nebula, but OIII win with some others. It's just a case of trial and error to see which suits best on the night.

    Very nice report John I got my dob out and cooled last night but the cloud hadn't broken by 11:30 pm so I gave up. Your description and sketch of NGC604 is spot on so I'm sure you did see it. Now I know where it is it's realtively easy with my 12". A UHC type filter helps make it and some other H II regions within M33 "pop" a bit more but you loose a little of the galaxies background glow. With your 18" you have a little light to play with though As you are finding, as with the planets, the more you study galaxies and other deep sky objects, the more detail you gradually see. Great stuff !

    Nice report Gerry I'm looking forward to observing M42 again. I'd only just got my DGM NBP filter when Orion was dipping rather low earlier in the year but I was impressed what that filter did to the famous nebula. Looking forward to more of that sort of thing !

    Great report on what sounded like a good night, I would love something to go out and look at apart from clouds and water failing out of them. M33 is one I have yet to try, at the moment the house is getting in the way until too late for me, sadly I am up every morning before the crack of dawn, which can even be nice if it is clear on a summer morning, now it is just damp and very dark. Last time out I did look at M31 but I always feel this needs a wider field than I can come up with, I actually prefer it in the M/N 190mm where I can get over 3 degrees but with a large exit pupil, probably too large for my eyes these days . You should try thr Viel nebula, again you can't get it all in any FOV with your scope but you will love what you can. Alan

    I use the GSO 6" F4 Newtonian + ASA 0.7x corrector/reducer which gives me a focal length of 420mm which, importantly, is also at F2.9 As Olly points out- such a fast system will require some application of thought to get the most from (it's not for numpties). The ASA corrector is expensive but is a whole lot cheaper than an a Takahashi Epsilon and you can also use the ASA corrector/reducer with any other Newts you might own (I have 5!!). Additionally you can use the GSO 6" at it's native F4/600mm - the Tak is fixed focal length. The 'halfway house' where someone else has done the tweaking for you is a Boren-Simon 6" f/2,8 Powernewton Astrograph . Again- not a cheap option at £1100 (vs £4300 for the Takahashi) but it overcomes some of the problems of the budget route in an 'out of the box' package. The sort of FOV you get at 420mm with an APS-C sized CCD - M8 & M20

    I have bought from Astroboot on several occasions and never felt badly done by. They are accurate to the point of brutality in their descriptions of items for sale and work an 'A1-A6' quality rating on many of their items. A lot of items are less than a fiver and are almost unobtainable elsewhere. I rate them as an honest, no-nonsense company. They are helpful, but don't go looking for a long esoteric email discussion about the pros and cons of something they're shifting for £3.50, for example. Read the description - it is often humorous. I mean who would think it anything less than honest when the description says something like: "a joke of a tripod which is wobblier than a wobbly thing and less stable than a blancmange"? They're not trying to pull the wool over anyone's eyes with that kind of talk!
