    This image was taken from Goldendale Washington in September 2016. Technical details: Imaged with a TMB 130ss at f/7 with an Atik 383+ Mono on an Atlas EQ6 mount. The exposure includes 5 hours of Luminance, approximately 1 hour each of Red, Green and Blue and 1 hour of H-alpha all binned 1x1. Collected with SGP and processed with Pixinsight. Large version here. Thanks for looking. Ajay

    darn windows I'm going to write to bill gates, lovely clear skys firstthing, I just got focused on the AR and lappy starts shutting down, 45min later it reboots and lets me log on and ive 99% cloud, thanks bill for killing my imaging session. but I carry on regardless and got a few cloudy frames. prom 1 oncoming limb upper very faint. proms off going limb lower. and another 10 min later. new AR loads of flaring going on, sorry its not very good but the best I could get. kit starwave 102, quark, asi120mc. thanks for looking, clear skys, charl.

    Its been a long, hard road indeed.....but finally I have my first image with the ASI 1600 and the TOA 130. I struggled with the palette almost as much as I did with calibration (flats were a major issue for the Lum and Red channels). I think a good cleaning is in order. I finally was able to get a handle on temperature compensation for my Boss II focuser. Your supposed to have a 5 degree temp swing to calibrate and I only had 2.5. But I figured it was worth a shot and it seemed to work pretty well--I only focused twice all night. All in all--I am just happy to get one done...it has been a while. I think I need to reprocess this data, and maybe try a super luminance (528 subs) for a lum. I am also considering Ha...but things are a bit too red as it is. TOA 130, ASI 1600mmcool pro, Unity gain (139), Astrodon series e filters Lum 190 2min Red: 70 2min and 100 30sec Green: 97 2min Blue: 71 2min

    Just seen that APM have quite a lot of kit up at reduced prices due to a move. Mainly APM binos but a few scopes and other bits in there. Worth a browse maybe. http://apm-telescopes.shopgate.com/category/3731323736

    Finally got some half decent skies to image the sun again. Managed to set up the 80mm on the EQ3-2 mount, and shoot WL and Ca-K, before some cloud started drifting in. Not much to see, but part inversion showed some nice proms in Ca-K. WL just shows nice granulation. WL, grey scale: WL, pseudo colour: Ca-K, grey scale: Ca-K, pseudo colour: Ca-K, part inverted: Ca-K, part inverted + pseudo colour: Ca-K, proms at longer exposure:

    This is a cheeky single 2 minute exposure of M42 taken from the Ballycroy international dark sky site in Co. Mayo in Ireland. I had intended to take a lot more data but that part of the sky was quite cloudy so I moved on. By the time it cleared I felt that M42 was a bit low. Also, M42 is done to death. :-) The corner issue is just due to badly calibrated flats. Can we turn off the city lights now please? Barry

    Trying out imaging with the 12", it was misty and then cloudy so just grabbed a couple of subs as the weather deterioriated. I always knew that the middle star in the handle of the plough was a double, but I didn't realise that one of those was actually a visual double too (I've since learnt there are actually 6 stars altogether). I did a very short exposure too, which showed up the three star separately, but the diffraction spikes in this one help highlight it. 30s subs, no guiding, 7 subs stacked.

    i have an ancient watec 120n (more about that later) but recently i purchased a ZWO AI120MC. i use a Computar 5 mm f/1.4 lens, sky studio pro software( interfaces with ZWO windows driver, cool!), xvid codec, 4 second integration. no guiding (of course). pointing at a circumpolar point north by north east approximately 45 degrees declination. i have been influenced by security and dash cams capturing, inadvertently, fire balls. why not do it on purpose? i have been for a few years now. sure, i capture meteors but mostly i get jet aircraft, satellites and... i upload videos to my youtube channel. everyone is invited to check them out. i also have orion all in one and an astroscope image intensifier on canon t1i and t3i. it is my opinion that there are more short dim meteors than long bright ones. there are more satellites than meteors and more jet aircraft than satellites. something else...you foe? cloudy nights? check out my star field time lapses. youtube, what can i say? full screen in darkened room, make sure the gear has HD in red, click and select if not. find an intriguing clip? get a youtube down loader for best quality on your local drive. try adjusting play back speeds.

    Hello, I have recently started to get interested in stargazing now that I am winding down to retirement. I am currently trying to resist going down the telescope rabbit hole at the moment since I'm still learning to hop. I do have 10X binoculars and a spotting scope for now and have tried some short exposure wide field photography. Just hoping for some clear skies. There was one gap in the last week predicted by clearskies at 4 o'clock in the morning, luckily I woke up and managed to see Jupiter's bands and 4 of the moons in a row using the spotting scope. It as a lovely sight that I will remember for a long time.

    In an earlier thread I showed the progress of my wife's amazing cross stitch version of the Orion Nebula. Today the finished project was sent off for framing but before it went, I took a photograph for posterity. Here are some stats and the finished cross stitch:- Stitched at the eyepiece The Orion Nebula (M42) and Running Man Nebula (SH2-279) This unusual image was hand stitched by Jane starting in June 2017 and is based on an image captured by me using an SXVF-M25C and 100mm TS 100Q APO Refractor mounted on a Mesu 200 Mount. I captured 18 subframes of 300 secs. plus 11 subframes of 100 secs. to produce the original image which has a resolution of 3032 x 2016 pixels and a 16bit colour palette. I then produced a set of 12 A4 size counted cross-stitch patterns for Jane to work from. The hand-stitched version has a resolution of just 216 x 216 cross-stitches (18 cross-stitches to the inch) and a colour palette of 82 colours. The whole circular image comprises 36,644 cross-stitches (the white surround was left unstitched) making a total of 73,288 individual stitches!

    This is my take on this lovely galaxy. 10hrs in total - 4Hrs @ 600s in Lum and 2 each in RGB also @ 600s. Its very small through my set up so the image has been cropped to show some of the detail. Quite pleased with the amount of colour in this shot. Hope you like it - there is another cropped version on Astrobin too. Thanks for looking. https://astrob.in/340960/C/

    I’ve always noticed whilst browsing suppliers websites such as first light optics and modern astronomy , there’s always a review tab but not many user reviews , and I’m guilty of it sometimes too but I do go back and leave a review , but it only takes a few minutes and find it helpful when purchasing to read any reviews so come on guys and girls next time your browsing leave a review for the last item you bought , think of it as helping each other .

    Hello This image taken of M106 and friends. I didnt know i could get anymore fuzzies. This is a 2 hour session from last night. Despite dewy conditions and poor transparancy. It was pretty much overhead. Thought would give ago anyway. Stars in the sky have being a rarity recently Telescope - 102mm APO ES refractor on a AVX mount Camera- Canon 450d unmoded iso800 with a Astronomik CLS filter. Duration 2 hours - 300s lights., Darks, flats and bias frames also taken Guided with PHD2 and processed in PS Of course improvement advice much appreciated Thanks for looking Dean

    Agreed Going from 8" to 10" is more like going from 16" to 20" which gives a quite noticeable improvement in image scale on those faint fuzzies. IOW I would also say..........go for it

    I suppose there must have been the odd piece of astro kit I regretted buying but I can't think of any. I have been well pleased with practically everything I have bought. What I'm not pleased about is the number of times I can use the kit!!

    Why not get a wide angle EP, something like the MaxVision 68 deg 24mm. That gives a 4.08 deg FOV and should act as an effective "finder", and gives beautiful wide-field views as well.

    I use a Gigabyte BRIX 2807. It is not Windows 10, it is not 8GB, it is not an SSD and it works perfectly with W7 in 4GB and all my astro apps. I run an ethernet connection to it (not WiFi) and use the USB3 port to a good quality 7 port powered hub. The hub breaks out to 3 cameras (finder, widefield+lens, DSLR) and EQMOD. When you don't do image processing on the remote PC, there is no need for a high-spec device. Quite simply: it just works.

    Hi Gert, What are your skies like? Are they quite dark? More aperture makes the biggest difference under darker skies in my experience. You are unlikely to notice a 50% increase in observable objects. A 10" dob though is probably the ideal compromise between aperture and portability. I keep one in my observatory, which is mainly for imaging, so that I can pull it out when the skies demand it. Enjoy your new scope

    Well said that man No system is perfect but constructive reviews submitted by actual owners, written with the intention of helping others, are best. There aren't many specialist astronomy retailers selling junk SGL's ADMIN already have this covered. See their post Posting Supplier Reviews from way back in 2013. HTH, Steve

    An LRGB image of a galaxy grouping in Leo, the image represents just under 12 hours integration time and was taken with my Esprit 150. I quite like the shot, since it illustrates the wide variety of galaxy types that are out there. I've included an annotated version which shows that some very distant galaxies are also present in the image. It also highlights the position of the somewhat featureless nebula NGC3193. Alan LIGHTS: L: 17, R:17, G:18, B:18 x 600s, DARKS:20, BIAS:100, FLATS:40 all at -20C.

    The Veil is one of my favourite objects to view from a dark site. I vividly remember my first views of it at the Isle of Wight last year and I have been keen to see it again. Unfortunately this object is completely invisible to me from my garden in London (SQM approx 18) even with my Lumicon oiii filter. So I’ve been wondering how the night vision monoculars would go with this object, particularly using a large fov. However at this time of year it was going to require an early start. The forecast looked good for this morning and I decided to give it a shot. I got up at 3.15am and checked the skies - nice and clear! Off I went to setup. To get a nice large fov of around 5 degrees I decided to use my newly acquired 72mm refractor. It combines really well with my az gti goto Mount and within 10 minutes I was set up, aligned and ready to go. Straight to the Veil and initial disappointment, nothing really to see. However there was some high cloud around so I hoped that this was the reason. I moved quickly on to a different target, the North American nebula and wow it just popped straight into the eyepiece with direct vision. Both parts of the nebula were clearly visible and there was nice detail shown within the nebula. I sat there for around 15 minutes enjoying the best views I’ve had of this object - much more ‘in yer face’ than the views I had at a dark site last year. Then looking at sky safari I noticed an object that I hadn’t observed before - the gamma Cygni nebula. I wasn’t expecting much so I got a bit of a shock when the whole 5 degree fov was filled with nebulosity. 3 parts of it really stood out with a dark channel just under the star Sadr very clear. Also there were several other fluffy patches of nebulosity dotted around the fov. I was very chuffed with this new find. Next I went to the Pac-Man nebula. This was an object that didn’t impress me at the dark site last year. I just found it a bit dull. Well tonight it wasn’t any better imo. However I didn’t have the image scale to do it justice - it was just a small blob really. I will make a note to have another look when I have my c11 out to get a bigger view and a fairer assessment of this object. Finally, I headed back to the Veil and success! The brighter eastern section was very clear and nicely framed in the large fov. The western part was however quite dim. But pleasingly the top of Pickering’s triangle emerged - another first for me. However I did feel that the NV didn’t work as well on the Veil as it did on the other objects tonight. So a good spring session and a taster for more to come later this year I hope. I enjoyed the grab and go aspect of this setup, particularly given the early start. It will be interesting to see the views with a larger scope (and of course from a dark site with no moon!). A few phone pics below, including a picture of the 72mm refractor with the NV monoculars (no balancing issues despite the long length of the eyepiece setup). Order of the object photos is North American nebula, Gamma Cygni, Pac-Man and the Veil.

    How are you connecting to the power supply? Are you connected directly or through the cigarette socket? I've had issues with mine that I traced to the cheap cigarette socket I was using. Voltage was dropping to below 8v. However, if the mount doesn't receive enough power it should stop slewing completely where your RA seems to keep going and is it the Dec making the noise? Do you have the handset? You can monitor the voltage on there while your skewing.

    As an ED80 user I think you may struggle with it on this set up. I have tried mine on a simple tripod set up and it took ages to settle down after finding and focusing on an object! The slightest breeze will also upset it. I used to own a WO72 and it is a great, light scope that can be used on a tripod mount or maybe an AZ4 mount?? Cheers Ron

    I looked and looked and looked at these options and couldn't find one that was reasonably enough priced so I took the plunge into kstars/indi/ekos - after some initial teething problems (there's no ubuntu mate image for a 3B+ so don't get one of those yet unless you're linux savvy and like frustration), the rest of the installation was pretty seamless and works nicely. The mount now is a wifi hotspot so I can connect and drive it from any device without requiring internet, so I can set it up on my ipad then when I've finished I can bring it inside and plug it into ethernet to download my data. If I had to do it again I would build it on a Rock64 much like wimvb did and there is walk through guides for that on this and other fourms - that way you get a USB 3 port and other benefits.

    That’s correct. The close double is Mizar, which can be split even at low power in a scope or high power binoculars into Mizar A and B. The wide pair which you can see with the naked eye is Mizar (A/B) and Alcor. @tooth_dr a lovely image of a very nice object. It was the first object I viewed through a scope having read a description of it by SPM in one of his books. It’s still one I look at on most occasions when out with the scope; simple but beautiful.
