    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.

    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/

    Hi all, I have had a go here with the Catseye Nebula, NGC6543. It's a real pain because the central core (the catseye) is tiny and intensely bright (I could pick it up on 1/10 expusures) but the outer shell is very faint. Unfortunately the difference is so great, and my Newtonian's diffraction spikes are so bright, that it wasn't possible to make a nice smooth composition. So here we go. Here's the overall nebula, 18 x 5 minute exposures each of Oiii and Ha, SXVF-H9, 250mm f/4.7 Newtonian processed in DSS and Photoshop. It's like a gorgoeus delicate flower. Need more work, though! And here's the exactly same view, but exposed for the core, 20 x 60s exposures in HA And here's a hugely cropped view of the catseye itself. Not highly detailed, as it's only a few pixels across, It's not going to win any prizes but I'm pleased to have captured the characteristic shape. 12 x 60s each of HA and Oiii. And here for fun is the core superimposed onto the main image, which shows just how tiny it is in comparison with its outer shell:

    I think most charge £150 for the mod but I may have mised one or two. One idea might be to keep your 350D for normal terrestrial photography and buy a used 1100D for AP. The 1100D uses the Digic 4 image processor with lower noise, higher max ISO and 4x the luminosity range as the Digic 3. There is nothing to unsolder, just the usual dozen or so screws, ribbon connectors and filters to contend with. A Canon refurbished Rebel T3/1100D is available on ebay for just over £200 inc carriage from a UK seller and quick delivery.

    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. Turning my scope on another target this evening fingers crossed for clear skies every one Sent from my GT-S5670 using Tapatalk 2

    Thanks Scott. I have the Skywatcher Skymax 127 Supatrak.....although the tracking is a bit of a mystery as it doesn't appear to work, i'm reaching the conclusion it's because I'm using batteries instead of a psu...I might have to make a post about it, see if anyone can shed any light on that issue. I think it's great as a first scope, it does everything I need it to (except for the tracking part) so I've been pretty pleased with it on the whole. Got my eye on upgrading the mount to the synscan AZ goto to help me find things more easily but also don't want to solely rely on that and get lazy. It's looking good out there right now, dry and clear, going to set up in a bit, fingers crossed

    That shows some clear improvement. Any chance you can list what kit / processes were used for the two shots? Might help the newbies understand the learning curve etc Im itching to get back out and shoot stuff.

    I'm buying the Celestron astromaster 130eq and it will be here on Monday. Dont feel bad, his purposes are differnt from yours. If you get one too big you cant move it. Also smaller ones take less time to warm up.

    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??) Clear skies !? Scott.

    no i cant see it here in berkshire, the light pollution is pretty bad here, I cant wait to come to wales, just hope its not cloudy. I have never seen the milky way before. As sad as that sounds. Just wish i could bring my scope, Binos will have to do

    ...is it blurry up close? I had my scope out for the second time tonight (twice in one week, eee!), still at the lower point of the steep learning curve but I had my astronomical climbing gear to hand (is this metaphor getting out of hand?) Anyway, just before 10pm Jupiter finally rose above the horizon (well, my neighbours house) and I got my first look at it (which was handy as it was something reliable with which I could properly align my finderscope, after looking at Pleiades through it all night but god-knows-what through the actual scope!) Using both the 2x barlow and 10mm eyepiece that came with the scope, Jupiter looked quite blurry. Removing the barlow made it look better but I assume this is simply because the blur wasn't magnified. I spent ages tweaking the focus but I couldn't get it very sharp. My question is where does the problem lie? Is it with the eyepiece, the motor (had that going for the first time tonight), the idiot running the show or something else I haven't thought of? The scope is a 200p on a HEQ5 (must post more so I can just put that in my sig!)

    I totally agree. It's the amateur cameras that have changed the most. This is going well but be warned that M33 wil eat up 12 hours while getting dramatically better all the time. (The next 12 wil bring more subtle improvements! ) A suggestion; you can download a free 'green noise remover' called Hasta La Vista Green from Rogelio Bernal Andreo's Deep Sky Colors website. A lot of the noise in this is green and I think it would help. I always run the original PixInsight version on my RGB images because green is a problem colour in imaging. Olly

    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.

    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.

    Hi Lisa and welcome to the forum. I think an essential bit of kit that all of astronomers have been using lately has been an umbrella! - lets hope the winter season clears up and then all will be forgiven. Sounds like you did a fair bit of research on here before buying your scope which is a useful strategy that will certainly be of benefit to you in the longer term. Hopefully you can hook up with a local observing group which will provide another useful resource to help improve your observing skills and knowledge of night sky. Also provides a good opportunity to look through others people's kit including eyepieces as you do realise you are likely to suffer from aperture fever from now on and I can also advise you that there is no cure! :grin: Clear skies for now and hope you continue to enjoy the forum. James

    I'm a lifelong continental cycle touring camper so I find this tiny caravan enormous. With its awning up it is really a spacious place to live. (The awning can be fully encolsed if you like.) Alas production of the tiny Puck model has stopped and they are going up in value but this cost about £4.5K here in France. I tow it with our turbo diesel Panda, incredibly easily, an still get nearly 60mpg. Hey, we blow off Limmos towing giant caravans!! Motorway is free, too. Serioulsy, it would be a great aid to mobile astronomy. Eriba Puck is the make and model. We're chuffed with ours, though we use it to get away from astronomy here! Olly

    Well, technically, car camping is also not allowed in the parking lot but astronomers having been gathering here for several decades so they allow this, including motor homes. There are several official paid and free campgrounds very close by but they are really not suitable for astronomy due to the tall pine trees everywhere. This shot of the parking lot was from last month.

    So the old "life after death" thing is in theory true?? Not getting in to God or anything just in the case of we re use and recycle atoms that were here from the start of the planet? Can further atoms from elsewhere in the universe though come through are atmosphere and become more building blocks on earth? I have read a book not sure who by it was a while ago and the scientist believed that atoms could retain information????? Bit far fetched if you ask me but he was the scientist not me

    Most people buy APOs for imaging. I bought mine for (future) imaging and (immediately) as quality wide-field and travel scope. Some people just like the aesthetics of refractors, and the sheer quality of the image (within the limits of its aperture). Quality matters, and there are differences. At the low end, reflectors do not always have perfectly formed mirrors, and such reflectors will show bigger differences in quality with APOs than high-end ones. A cheap synta or GSO reflector will generally not be as good as good as a high-end scope with 1/10th lambda mirrors or better (though GSO and Synta can make those as well). Likewise there are differences in apos as well. Your Skywatcher 80ED will be beaten (by small margin) by a similar aperture scope from APM or Televue. Finally, buying (big) apo refractors is a bit like buying a sports car. It may only hold two people, and very limited luggage, but it is fun, aesthetically pleasing, and fast. Buying small apo refractors is to complement a big reflector is more like buying a small hatchback for shopping next to a large family car. Both cars are practical, but have different strengths.
