    I firstly attacked this target with my 3nm Ha filter and I have to say that I love the detail it pulls out of the sky! So with a forecast of a number of clear nights I thought I'd try a colour version. Collected the data - always the easy part and then processing - Boy was it hard. I think I've reached a place where it's OK, but I think I need to learn that there's just too much red when I add all of the Ha to the red channel. There looks like a gradient in the top right, but from what I can see it's the Ha data, and it really jumps out on this small version. Well I like to be heavy handed I suppose, so here it is, Sh2-157 and it's friends! If there's anything you see that you don't like or you think should be done differently then I'd love to hear it. Details M: HEQ5 T: Takahashi FSQ85 0.73x C: Atik 460EX mono with 3nm Ha and Baader RGB filters 9x1800s Ha 26x240s in RGB Flats used for all filters.

    Another clear night, another image made This is IC 1396, a huge molecular cloud in Chepeus at the border of Cygnus constelation, the "Elephant trunk nebula" is seen at the lower right on this field, also any dark and intrincate dust nebulas are present in this area of the sky giving a touch of beauty to the scene. Only two hours worth of data on this one, the moon was present at the first hour of capture so one hour worth of 10 min. sub went to to trash bin...not good enought. Setup used was: Altair astro (Astro Tech) 200mm f/4 imaging newtonian, Baader MPCC, TEC cooled and modded canon 350D, EQ6 go to mount, autoguided with a GPUSB and a 50mm modified finder , stack of 12x10 min. @ 400 ISO, no darks used, only bias and flats (40 each). Hope you enjoy: http://www.flickr.co...in/photostream/ And in mono, if you prefer: http://www.flickr.co...in/photostream/ Greets from Portugal, Luís Campos

    Hola, Bit by bit over a couple of days I managed to build a wooden box specifically designed to accommodate eyepieces and related astronomical equipment. It was a trial and error, but finally finished. I'm aware the top level will require a bit more work. I'm thinking some divisions for accessories. I will also install a red led light, and perhaps caster wheels as well as a side pocket for star maps and similar materials. I'm saying that, but I might get lazy and just live with the box as it is. After all, it contains the the content of two flight cases and still has some room left. Bear in mind this one is not a travel astronomy box. Here are some photos...thoughts are appreciated

    I paid the 80% final payment (deposit last year) for my APM 7" triplet Apo refractor this year so I am well aware of how much you can spend in this hobby. Probably best I do not add up what I have spent over the last 20 years since I started (paper round money to buy a 4.5" reflector was the first thing). Heaven knows what happens if I fall to the dark side and start imaging!

    From this morning. Finally got some clear skies after weeks of clouds. Altair is at the frames edge with Tarazed being the guide to Barnard 142 / 143 which is easily seen in binoculars and sometimes the unaided eye under a dark sky. Pentax K-01 with SMC Pentax 67 200mm f/4 @ f/5.6 376 seconds @ ISO 800 Camera / lens riding atop 8" SCT. Thanks for looking...... Barnard's E by Nightfly Photography, on Flickr

    This badly needs some more data, hence WIP. Taken last night, just 50 minutes each Ha, OIII and SII in 10 minute subs using an Atik 460EX on a Megrez 90 with 0.8x FR Even though I used Annie's action for the Hubble palette I found this quite difficult to get something that I liked. Dave

    The advantage of having a birthday close to fathers day. The Mrs has seen fit to buy me some William Optics Binoviewers as a present. Wow! I dropped the hint but never expected she would actually get me some, well chuffed. Here's a picky:- The sun is starting to break through cloud as I type this so hopefully may get a chance to use them shortly. Al

    I need to gather more data (& my framing of this image could be improved) but I'm pleased with my first NB imaging. There are 12 x 5 min subs and 3 x 10 min Ha subs taken with QHY8L and my TS115mm flat apo with Riccardi reducer at f5.2. Collected earlier in the month before this awful weather arrived in Devon. NEQ6, ST80 with QHY5 and Phd. I used a frame with a satellite trail which you can see but nevertheless I feel encouraged. I'm learning more about processing too; all done in Nebulosity as I don't have PS (yet). All comments welcome . . . as I know there are many on the forum with far greater experience . . . and it helps motivation. 8 bit jpeg attached. Barry

    I don't regret any purchases either. although I have a mental tendency to only remember the last piece I bought so it seems somehow cheaper.

    In some ways I feel quite fortunate, as my interest is exclusively focused only on visual astronomy with quite basic set ups, free of any electronics. So at least there is no doing a bit of this and a bit of that. The money spent on the hobby, has therefore been channelled largely into a set of premium eyepieces, which has taken approximately five years to build up. I would like to remain stubbornly in denile though and would not like to tot up what in retrospect I have spent, even though some of my gear has been purchased second hand, ignorance is so they say bliss. The main consideration though, is that at those times when it gets put to use, it all feels completely worth it!

    Captured last night in the brief break between Moon and clouds. 10 x 120s 10 x 180s ED80 + EOS450d on NEQ6 Processed using DDP in Maxim, then a bit of curves and noise reduction. Tony

    With continuing bad weather, I'm looking over my present data and seeing if I can improve on the processing. This is a slight reprocess of the Cygnus Loop taken with the Atik 314L+ mono CCD camera with Asahi Super Takamar 105mm f2.8 prime lens at f4, filters were Astrodon 5nm Ha, 3nm OIII and 5nm SII. This is basically Ha and OIII - the SII showed little and what there was seemed much the same as the Ha. Ha to red, OIII to green and OIII + 25% Ha to red. Stacked in DSS, aligned with RegiStar, combined and processed in PS with GradientXterminator used to remove the gradient caused by the full moon on some of the subs.

    That is not quite true! So long as you are not the one selling the equipment, you are allowed to post links to things. http://www.teleskop-express.de/shop/product_info.php/info/p5965_TS-PHOTOLINE-2--0-79x-Reducer-4-element-for-115mm-and-130mm-APO.html We don't allow dealers to post commercial links without asking permission from admin first, and we don't allow people to post adverts for private kit outside of the 'classifieds' section. Other than that, links are fine but the idea is to keep SGL a forum for discussion, rather than a market place.

    Wow! I was even taken back by the 9x50 finder scope!!! The SkyWatcher Explorer 200P is something else.. With it being patchy clouds last night I mainly concentrated on viewing our moon.. The detail was genuinely breathtaking. Also shared the experience with my brother who was shocked by what you can see.. (He lives in deep countryside, so he'll be seeing me more from now on!) Now really looking forward to the next clear night!

    You don't need huge performance for Astro work so you can get something without all the "bells and whistles" if you wish. I would certainly go for Win7 as almost all astro software seems to run on it - Win8 is a pain at the best of times (we have to suffer it at work on a few machines) and not all astro programs/drivers will run on it. One thing to look for is a machine with lots of USB ports!! Some are very lacking in this department. Try taking a look at these folk: http://www.morgancomputers.co.uk/default.asp as they seem to have sensible kit at reasonable prices - both new and second hand, which is often little used or even unused! (usual disclaimer).

    If you really want a shock, work out how much you've spent per hour of observing time I've been good this year and have only bought one eyepiece. (well I did buy another cheap one for use at public meets and I have been given another one but only bought one real eyepiece)

    I doubt I will get a chance to see it due to cloud cover, but according to the GONG images the southern prom has become a lot bigger in the last few hours. Have a look if you can.

    if you want high power views of planets on a budget you could do worse than the skywatcher 150mm dob. it has a good focal ratio of f8 and a focal length of 1200mm. the additional aperture will allow higher theoretical magnifications but planets will always be small in UK seeing. average planetary magnifications are between about 120-180x in the UK with perhaps a little more when seeing is very good. the key is concentrated viewing and you will eventually see quite a lot of detail. you can get higher magnification on double stars and the moon on more occasions. compared with an average 3" refractor, the views with the above scope will be substantially better on all objects. I'd recommend a red dot finder and if funds allow a right angle correct image finder. plus a decent star map. armed with these and even the standard eyepieces that come with the scope you'll see a lot of objects well.

    I should have add if you install something like Ubuntu you'll probably get those proprietary drivers included anyway on installation. I run Fedora which by default only uses Open source drivers, but the proprietary drivers can be made to run on Fedora with a bit of extra effort.

    Aenima, Have you tried placing black electrical tape over any potential light paths in to the camera? It may help identify a location if nothing else. I hope you find out what the issue is. Dave

    Hi, As Peter has stated, you will need a step ring. Both of your Nikon lenses have 52mm filter threads and the Orion LP filter has 48mm (T2) thread. The following adapter will do what you require: - http://www.teleskop-express.de/shop/product_info.php/info/p1427_Adaptor-from-T2-thread-to-M52---for-projection-photography.html Hope this helps.

    After weeks of poor seeing and my general aversion to staying up late I have finally done it! Let the dog out for a wee and saw a gap so got the old Tasco out and pointed at what I hoped was Saturn only to find my skills have improved more than I thought and I was indeed looking at the ringed wonder! Very very small in the eyepiece and a bit wobbly due to my poor equipment but at only 60x mag when the wobble stopped I could see the gap between planet and rings (just)! Thought Jupiter was good but Saturn is beautiful, looks like a cartoon! I turned 40 yesterday and this has made my birthday weekend!

    This was the result of my first remote imaging session - I was only 20m away from the obsy - but I was mighty pleased that everything worked fine - I'm not sure if I've got the bottle to go to bed and leave it all running yet though! Thanks to Robin M and Chris Shillito, the dome synced perfectly. Almost full size here: http://www.flickr.co...66913/lightbox/ This was 6 x 1200s using an Atik 460ex through my FLT98 at f5 on an EQMOD'ed NEQ6. The image was acquired with Nebulosity 3, guided with PHD, plate solved with AstroTortilla and processed entirely in Pixinsight. I think this is a lovely target (my daughter can see a face in there, so she likes it too) - so I'm planning to get a shed load of data and make this my first full NB image (weather permitting of course.)

    Ok, to see saturn, have a look where the sun is in the sky at 1pm tomorrow , this is to the south.. Tomorrow night at about 11pm look in the same direction and 25degrees above the horizpn youll see a star...thats saturn. The chart below shows you what 25 degrees is by holding your hand at arms length so turn your hand to the side so your thumb is at the horizon and your little finger is approximately where saturn is. Start with the lowest magnification ie 20mm eyepiece and work up.

    Hi Barry, it is a little difficult to work too much with your 8 bit JPEG as it has a whole load of compression artefacts (not your fault, just a by-product of JPEG production). However, this is an excellent start. Working with the original data, try applying some adjustment in 'curves' in Nebulosity to brighten the image and reveal some more detail while keeping the black layer dark. Try aiming for something like the following but without the JPEG artefacts:-

    Pig, The only way to deal with temptation is it yield to it. Buy both, Keith talks sense. If though you can only afford one I think I would go for the one that would get the most use, 12mm. The 10mm is one hell of an eyepiece, I wish I had kept mine. Alan

    Don't forget... Polar scopes need to be set up too! Aim at something distant in the day time, turn the mount round and check if target stays centred, or Google polar scope set up
