    Hi all, This is the first time I'm using my little ED80 and a TS Photoline 0.8x reducer / flattener togheter with my TEC cooled and monochrome Canon 350D I'm blown away with the sharp pin point stars this combo produces, and the detail with only 480mm f/l is very good, I can't wait to get some nice clear skies (will it ever happen...?) to go for the veil, north america, etc... This is a work in progress image, hope to give it another two or three hours before the moon gets in the way. Hope you enjoy: Best wishes, Luís

    Just spent some fairly frustrating time trying to catch the sun between the clouds. Got 21 decent frame and stacked these. Focus seems to be OK, but might want to work a bit on processing

    Mark makes a good point about the eyecup and this allows you to really concentrate on the field at hand. I bought a 20mm TV plossl as this provides the right ball park exit pupil (this is what matters most I believe) and the narrower field allows the local brighter stars to be excluded from the view which again helps I understand. As for the 'coffee colour' if anyone offered me a cup of coffee the colour of the weak very minor yellowish tinge I sometimes see when changing between eyepieces in my Radians and plossls I'd certainly send it back. it's there I think but hardly an issue unless you look for it. as with all faint objects, what matters most is dark skies and concentration, not the kit you use necessarily. as John said though some objects need all the help you can get. Personally I will use the 20mm plossl for things other than the horsehead (like solar observing today) and therefore other factors come into play. I love my TV plossls.

    I viewed the HH from the Lucksall star party site using Luke and Sarah's 16" Dob. We were using a 19mm and 24mm Panoptic again these belonged to Luke and Sarah. I have read that a 25mm Plossl is the 'magic bullet' together with a H.Beta filter. I live very close to the Lucksall site and have similar skies but have not seen the HH from home using the 10" Dob. I would choose the Televue 25mm Plossl - I prefer a rubber eye cap which the Hutech does not have. You may find this article interesting - http://freescruz.com/~4cygni/haggisizing/astro/HH-sense.htm

    Thanks for the heads up people!I set up just now,great,intermittent seeing (between clouds).Awesome again,Shaun you are right about the mag,I'm using the zoom + barlow wound out right now-180x and the spots are still sharp.I zoom back for the faculae,granulation(88x) and zoom in for the spots.I like the zoom for solar,using it as about a 3.5mm-7mm right ATM.Very active sun right now,a Ha scope would sure be nice......

    Gordon, I am surprised more folk don't use high mag when observing in white light (remember my focal length is only 500mm), there are some cracking details to be seen with the wedge, if you have a fine tuner. It has been a little hazy here also but a big gap is about to become available

    Hi, The promised clear evening did not materialise again last night, by 10.30 pm the clear blue skies of the earlier hours were replaced with thick black clouds, how can they get the weather forcast so wrong? Any how the world cup football was nothing to brag about either so I decided to reprocess the data from a few nights ago as I was not really happy with the star shapes and what PI's deconvolution had done to the image. This one is a mix of simple histogram stretch and and masked stretch through a star mask. There are still some chroma noise around some of the stars but to my eyes they look more natural and subtle, the colour stauration looks more natural too . Hope you like it. This is reduced to nearly 20% of the original size to keep SGL happy. Regards, A.G

    Add some moonlight, a lot of light pollution, an unguided refractor poorly aligned, a DSLR at far too high an ISO, the heavy handed use of DeepSkyStacker and APS and one old amateur astronomer. Result personal happiness!

    Hi, here is my go at the Pelican. The Data was collected over four nights: Ha- 12x1800, Astrodon 5nm OIII- 5x1800, Astrodon 3nm SII- 7x1800, Astrodon 5nm, Total: 12h I was aiming for a sort of classical Hubble palette and I think I got something close with colours that I like. Processing was done in Pixinsight and capture with Nebulosity 3. I used Astrotortilla for the first and it's really great (although it forces me to capture in windows rather than mac ). The equipment: -Megrez 72 @ 4.8, SXVR-H9 -Heq5 -Guided off axis with SX Costar and PhD2 Link to astrobin: Comments welcome, thanks for looking! cheers Epicycle

    I sent the big payment for a Paramount MX+ today. It did make for cringe but I kept telling myself that it's for a lifetime of observing pleasure & astro photography. I hope it's worth it but all the reviews tell me it's a really good mount. I will post a picture when it's all setup. I got on the waiting list about 6 weeks ago so I hope to receive the mount this month if all goes well.

    I feel hugely privileged. Today I had my first 'fix' of what solar observing can be, I think. I had great views of the sun early this morning. Proms, spicules, sunspots and a whole surface alive with detail. I was awestruck. It got hazy during the day but, just some minutes ago, I watched the sun as he fell below my all-too-high horizon (the roofs behind my house). Gone was the huge M-shaped prom I'd seen in the lower left of the disc in my view (west limb?) and at the top (south limb?) there were massive new proms. At the bottom of my disc, several new proms, blasting into space. And spicules everywhichwhere. Even my missus was impressed. And that's a result, believe me. So, up in the morning and down at night. Ain't there just something so right about that ...? I plan to get a white light view working simultaneously. Will be in touch with FLO to fit out my Dob. :-) For the time being - man, I'm a happy bunny! Life is bright.

    Nice Report DD, I went out late on Friday just to catch M6 and M7, but after seeing both of these (I get 6 minutes of viewing M7 through the gap to my south) I sat down, then just lay down on the lawn and spent an hour just watching summer wheel across overhead. When you spend a little time just looking at the milky way you notice all the dark bits, bright bits, spread-out bits and knots of stars. I was pretty well entranced until some little night horror tried to crawl into my ear and spoiled the atmos.... I do like the summer sky, even though you have to stay up until loony O'clock to get much from it, once you start getting the return its well worth the time. Mick.

    Hi Rob, JTV do not record anymore though which is a shame but I do have another channel with New Live Stream that does - https://new.livestream.com/spaced-out/events/3006293/videos/51269110 I have not used the channel much so all the clips here are test runs but they do show you a little sample of what can be done. As for JTV not sure what your issue was but if you want to try again I'm hoping to get on there again tonight, fingers crossed! Best regards Karl

    I finally gave my ASI120mm it's first planetary light last night and I must say I'm continued to be very impressed with the results it is giving. These are easily my best Saturn images to date and there is detail there that I have not seen in my images before, you can faintly see a small storm and the contrast between areas is well defined although it may be a tad presumptuous to say the hex is clear. Seeing was pretty good too but there was an ever so slight breeze which did bounce the image around just a little bit, but it was still 24°C after midnight so it was a lovely session and with the milky way slowly rising I think it might be time to crack out the dslr and polarie too. I will be ordering a filter wheel and some filters this weekend too, that seems to be a priority. If the shots continue like this I think it will be worth mastering processing a bit more as all I have done is a basic stack in AS!2 and wavelets in Regi. What more could be done? Will winjupos improve it any more? The other thing is the frame rates of the camera using firecapture, my first unbarlowed effort I was getting around 60fps which sounds about right and I know as you up the exposure it slows down but using the x2 I got 27fps and x3 14fps, can I make it record any faster? I had already used the ROI and upped the gain to get those values and if I'm honest I'd rather not use the gain so high but if it can't be helped then fair enough. Any tips would be greatly appreciated. All images were taken with a Skywatcher 6" f/8 newt and ASI120mm. The larger pic was with a Tal x3 barlow.

    Natalia is a good solid female Russian name and i think certain scopes (depending on size) should have female names.

    I expect the person was using Pacific Kelp which works for the West coast of the USA, Canada and South America, but is invariably incorrect for Atlantic weather? They just need to buy the more expensive Atlantic Kelp. That would be the Eastern Atlantic Kelp not the Western Atlantic Kelp. It is an easy mistake to make.

    re the headaches, what scope are you using? I find dobsonians much better and more comfortable for observing visually. equatorial mounts often require some gymnastics to get your eye to the eyepiece. comfort is an important factor for me when observing. re the eyepieces, I agree I think it's lack of centering or the scope moving when you remove the eyepiece and replace. you'll get the hang of it soon enough. the moon will be better positioned from tonight again so maybe practice on that if clear.

    It was super clear up here in the northwest last night. We have had quite a few clear nights in the past month, but the MW has to battle with the summer twilight.

    Alcor and Mizar are part of the Ursa Major Moving group, and are actually part of six-star system. Alcor A and B are a binary system in themselves, yes. When you split Mizar and Alcor it is the main stars that are referred to.

    I was equally frustrated last night, being right on the border of a cloudy area and with the skies clear to the north and west. I gave up at midnight when it became obvious things were not going to improve. ChrisH

    Jules I have a SkyTee 2 mounted on a Berlebach wooden tripod. I wanted to buy a used CG5 2" tripod but could not find one, so I went and bought the Berlebach. The system is very stable and the slow motion controls are very good. I use my Skywatcher 180mm Mak/Cass and it works very well even on high magnification. I can't totally answer your question although I have taken many good solar photos with my 4" Astro Tech frac and a Canon 50D DSLR so I cannot see why the system would not work for the Moon.

    The forecast for my area was showing not a cloud in the sky. As in, the current observation said "not a cloud in the sky". I wonder if the people providing these observations ever bother to look out of the window?

    I was curious as to how far away the clouds were, so I plate solved the image and looked up the altitude of some of the visible stars on Stellarium. That's Capella at the top right, I was looking NNE. τ Auriga, where the cloud band transitions from twilight to daylight, was at an apparent altitude of 3.7 degrees and θ Aur, near the bottom, was at 1.4 degrees. Assuming the cloud was 50 miles up, this would put it several hundred miles away if my trig is right. I can't give an accurate answer, it gets complicated with the curvature of the Earth and atmospheric refraction which makes it possible to look past the horizon, but I think I was looking at clouds somewhere off the west coast of Norway. I find that pretty staggering. Double checking on Google Earth, which has a handy 'show daylight' feature gives a sanity check. Thanks very much. There are some other images of them in this forum, on page two. Here's a really nice one.

    PoE works wonderfully well, but mind you, it is usually 48V in order to supply enough watts by means of limited current, so you wil need a ower converter at the other end - one that doesn't dissipate all the leftover energy as heat (i.e. switched). /per

    I have been sitting on some Ha and OIII data for this target for a while, hopping to add to it and catch some SII to complete my first narrowband tricolour image. Unfortunately the weather has had other ideas, so I decided to process what I have so far as a HA-OIII-OIII tricolour image . Ha = 5 @ 1200 seconds (shot on 20th June) OIII = 9@ 1200 seconds (shot on 22th June) I am pleased with the detail, it just needs more time at the scope to bring down the noise and bring out the faint stuff and then some SII data. Thanks for looking Mike.

    Thanks, this version is with a bit darker background. I kind of like the brighter background though on a daylight moon. Would have been nice with a color cam for this
  41. 1 point
    Well.. here we go... when I get more time, I'll drizzle stack it in PixInsight. Roughly 2 hrs each channel. Colour is via PixelMath with weights for Ha, SII & OII were R=SII+0.8*Ha, G=0.2*Ha+OIII, B=OIII

    Try Astrotortilla. It will automatically take an image, plate-solve it and more. http://sourceforge.net/p/astrotortilla/home/Home/ Here's an excellent tutorial for installing it too: http://lightvortexastronomy.blogspot.co.uk/2013/08/tutorial-imaging-setting-up-and-using.html
