    Always worth remembering that the likes of Galileo and other iconic astronomers - you know, the ones who discovered the things we look at - used small telescopes with optics so bad even cocacola would use them for the bottoms of their bottles! Your daughter is awesome, as is your scope. I hope you both enjoy it.

    Another go at this large but faint target M33. A stack of two 600s subs @ ISO1000, no darks/flats. Camera - Fuji S5 Pro, scope Altair Starwave ED80. From dark sky site in Mid Wales. Dont think the autogiuding was the best as one of the subs had eliptical stars.

    Just to add more food for thought, as a general rule of thumb the brightness of an object will decline as you up the magnification. If I up the mag twofold, say, I'm reducing the image brightness by a factor of four. If I keep on doing this eventually details just disappear. On the other hand, increasing the mag does make detail more apparent, so, as you can appreciate, we're now at a trade-off: will increasing magnification gain more detail even though I'm making the object fainter? I've found that playing around with this trade-off - dependent on the evening's seeing (I've found that LP doesn't really affect planets) - does make a difference. Even as little as 1mm increase or decrease in the mag - about 10% to 15% difference of magnification - can be quite surprising. You'll probably find that on a decent night your sweet spot is around 140x to 160x on viewing Jupiter and you will probably only be able to push 200x on the most excellent of excellent nights. With this is mind, I think barlowing your 10mm on an f/5 was a tad optimistic. You've got a wonderful 8" telescope reaching out across the universe some 675,000,000 kilometers and I'm sure - on another better evening - you will be able to see the Great Red Spot, those delicate reddish-brown belts, a darker, greyer hue to the Polar regions, and so on. You'll be able to trace the movement of the Jovian moons and observe their play of shadows over Jupiter in times of transit or of their eclipses by Jupiter's own shadow. From time to time, if you want to enhance that colour of the giant maybe a light blue filter will work nicely, or a Wratten 11 or 12. If you can, try to sit with Jupiter for a peaceful twenty minutes or so on your next observation session and I'm certain they'll be moments of great clarity and seeing. I've been following Jupiter since late July and every week it gets just that little bit better, the moons are getting brighter and more detail can be tweaked from the planet. Stay with it and as the weeks go by you will notice quite a difference.

    If I had been treated like that I would have gone home, put the kettle on, and had a nice brew.......... then, I would have: Called the shop. Explained that I was new to Astronomy and was looking to buy a nice new telescope. I would explain that the shop had been recommended by a friend as being a great place to buy from, but that I needed some help. I would mention one or two (fairly expensive) telescopes that I had been recommended to consider, and ask for their help and advice with "all the other stuff I might need to go with it" At this point you can probably imagine the £££ signs starting to cloud their vision at the other end of the line! I'd keep this going a bit further though. Making them build a considerable list of items and accessories, then make them add it all up for me..... "do you have it all in stock?" "how much for delivery?" "ok, sounds good. So, how much is that altogether then?" "How much?" "Great, that seems very reasonable........ however....... I'm afraid I don't do business with shops that are rude and discourteous to customers, and who snigger at people who only have a Celestron 114eq...... good day!" Click, burrrrrrrr.......

    Visit the other shop and just call in to see what they hold, see if they are any better. Could they be worse? If the internet doesn't bother you ring Alan at Sky's the Limit for appropriate bits. When I ordered 2 eyepieces from him he did point out that I was either mad or brave - which was an accurate description of the situation. He was nicely warning me, then I explained the scope(s) and the reason for the eyepieces. Said previously your 114 is bigger then any of the 5 scopes I have. I am sat here trying to work out what the consequences would have been ahd he passed to same comment to another woman who posts on SGL. The picture I have in my mind is "Messy".

    Great report. I'd describe the Orion Nebula through my 16" (even at home with bad LP), 13mm Ethos and UHC filter as completely ridiculous. It's the only object that when presenting it to my occasional observing buddy, warranted the use of the word 'behold'.

    I don't think so. I would say instead that we seem to agree that the person in the shop was unprofessional, unkind and inconsiderate. Yes indeed, people are who they are.... but shop assistants engaged in serving customers in a rude and unprofessional way most certainly can change their ways. They can realise their mistakes and modify their behaviour (learning) or they can be warned about their behaviour by the shop manager or owner. If the person is the manager or owner then they learn via complaints, poor sales, or by reading forums such as this one. Absolutely! No need to worry about it, but you don't just accept rude and unprofessional behaviour. You deal with it..... then move on.

    When you go into a shop that sells astro gear, you can tell the difference between a sales person and an astronomer. A sales person will try to sell you the biggest and best scope because they are earning commision on every sale. If the sales person is an astronomer themselves, then they will listen to you and your wants/needs and advise on the best way to go. When i bought my first scope, the guy in the shop (who is an astronomer and a friend of Sky at night tv show) took into consideration my disability(wheelchair) and guided me towards a scope that was half the price of the one i had in mind (i was actually going for a 114mm), but i came out with a 90mm on an EQ mount. Summary: Never buy a scope from a person that does not know their backside from their elbow. If in doubt...............GO WITH THE FLO http://www.firstlightoptics.com/

    I'm a truck driver working nights so not at home when it's dark much, but I collect milk from farms so always take my binos out with me for a bit of observing. It's great working nights, in fact seeing so many meteors and fireballs when in the truck along with noctiluscent clouds is probably what got me in to stargazing in the first place.

    Thank you peeps the first one was with my 200p and eq5 the spikes are normal with a newtionion but the second one is from last night and was done with the evostar ed 80. Unguided 70 80 sec subs iso 800 and 1600 half and half. Its surprizing how difficult this one is to capture the nebulosity so I had to wait for a really nice clear night. Stacked in deep sky stacker and processed in photoshop. My blog and utube channel have tons of info and a set of ps tuts just google boodlewoodle and you will find it.

    The Eastern Veil is the brightest segment followed by the Western part then the somwhat fainter and less distinct Pickerings Wisp. There is a useful location map on this web page: http://observing.sky...1/NGC_6960.html The star 52 Cygni is bright enough to been seen with the naked eye. Thats where I head for to find the Veil. Use your lowest power eyepiece - it's a huge object as can be seen from that map. Dark skies show it best of course but sometimes you have to make do with what you've got !

    I would think quite accurate, modern Science can predict from known facts the general movement of the Heavens as we see it from Earth, hence your published star position tables and relative Astronomical data which is updated and republished from time to time John.

    Galileo had far worse optics and discovered absolutely loads, he'd have dreamed to get an eyepiece with 50 degrees AFOV, or even 70% odd reflectivity, unlike the closer to 88-95% of today's amateur market.

    Hello Lisa and welcome aboard. When it isn't cloudy I cannot see the Milky Way in Staffordshire (my bit of it anyhow) due to light pollution. You are indeed, fortunate. Don't be shy about posting here. It's easy as you have no idea who you're actually talking to and aside from anything else, everyone is very knowledgeable and very friendly Have you told us what 'scope you have (or have I missed it??)

    Think that was the same shop I went to visit when I was looking for my first scope about 18months ago after asking loads of questions and taking advice on SGL, told him what I was looking for and how much I had to spend and all he seemed to do was try and talk me into getting a bigger scope which was a lot more then I could afford and saying how much better the views would be, so the visit ended with me not getting my scope from him and him not getting a sale.

    If working then realistically observing means Fridays and Saturdays. To me this "seems" obvious but I only know of one club, in a total of 4, that actually has the sense to arrange their observing on this basis. Friend who sails said that astronomy is like sailing, best considered when retired. Earlier nights mean you can do some earlier in the evening, however a large scope and complicated setup tends to work against this. One of the reasons for a small grab and go set up. Which is where a half reasonable 80mm achro of say f/7-f/8 would be a good instrument. A 150 Dobsonian is another small and quick option. Cool down is not an option for consideration. It has to be understood that you are talking that about a convenient and opertunistic hours viewing. Annoying when you get that clear stable night but with work the next day. How many bought their scope with the idea "Can I take this outside and be observing in less then 10 minutes?" Because for 1.5 hours possible one Tuesday evening that is what you need in equipment. On CN it was once asked: Will I see more through a 10 inch reflector or an 80mm refractor? The 10" has the higher potential but the 80mm will get used a lot more. I guess many 10" and 12" scopes do not get used owing to the hassle, have read it here enough times. Equally for a small scope you still need the bits. For short durations there is also the situation of being prepared before hand, spending 20 minutes locating all the bits is lost time. I now have all the bits for one scope in a trolly bag for that scope, eyepieces (not your best, I use the TMB clones), tripod accessories, book, torch, anything. Oddly enough it works. Preparation also means having an idea of something to go look at. Standing there thinking "What, Where? " as I have found is not a great deal of use. Have you a list of 5 things? If like myself you are in a town then knowing somewhere dark(ish) is useful. Easy to have a 20 minute drive and observe with binoculars, although more sensible if single. Relevant other halves would i guess find it odd. Also getting all bits in a car and organised is time. I have an ETX-70 for this, tripod and scope are one unit and easy to drop in the car, 3 eyepieces, power lead from car to scope. 5 minutes to set up and align and I am viewing. Accessories when in a car are easier in a plastic storage box on the rear seat, Don't expect to see the whole of the Messier catalogue either in an hours viewing.

    To move the worm a little away from the driven gear (and thus loosen the worm): Use a 4mm Allen key to loosen a little the 4 nuts securing the worm to the mount. Use a 2.5mm Allen key to turn the adjusting setscrew clockwise a fraction of a turn (yes, tighten the setscrew to loosen the worm). Tighten the screws either side of the setscrew first, then tighten the other pair of screws. If the worm was too tight it will now be easier to turn. Check the play in the gear. This is one adjustment that is critical - adjust again ( and again) if necessary to get a worm that you can easily turn with your fingers but with no discernible play. Good luck.

    I'm a chef. I get up at 7am, and finish at around 22:30. It's very rare i get to observe anymore. I usually get a break in the afternoon, but that's usually just enough to eat and smoke. Sometimes i'l do some solar observing. Waiting to hear back about an interview i had last week for a software testing position. 37 hours a week and flexitime.... No evenings, no weekends, no stinking like a deep fryer, no moody girlfriend, and definitely no minimum wage. Fingers crossed!

    M32 is close to M31 but clear of the galactic "halo" from the larger galaxy. It resembles a brightish fuzzy star. M110 is much fainter and a little further from M31, on the other side from M32. It's easy to miss in less than dark skies.

    That's a very nice way of doing it. When I get to do mine I intend to use a 150x150 square box section with a flat plate welded to the top. The central mounting bolt will be accessed through a hole cut in the side. This, for me, is the simplest solution. No machining, no tight tolerances and easy to fab up. I don't subscribe to the whole "wobbly bolt" thing though. I have done the calculations on the bending moment required to deflect a 16mm bolt, and it is a lot (IIRC, something like a 50Kg end load at 90 degrees to the axis of a mild steel bar 125mm long deflects the bar by half the width of a human hair). 4 x 16mm bolts are not going to go anywhere, especially if they are in tension, like Gina's setup.

    For DSO photography you really want: A short focal length ED refractor A motorised, sturdy EQ mount GOTO is advisable An ED80 on an HEQ5 pro would be ideal. You can just about get away with an EQ5.

    I,v finally finished my Tal. i,m pleased with its performance and its lighter and more convenient to use as a grab it and go. Plus it dosnt bother my other half as much when it lives in our lounge. I will drag out the 8inch newt for DSOs etc. i made a spongy hat for the rigel, even though it dosnt seem to suffer as much from dew as my telrad on the newt. The scubapro is a stretchy band for sorting the balance after re-aligning the tube during the night for best positioning. The good thing with a stretchy band i find ,is you can move it in relation to the changing weight of the ota. The solid dec knob in the ally knob set does allow much more precise feel than the flex ones. Just waiting for a clear night .......
