  1. My next door neighbor has shown an interest in space and science in conversations we've had over the wall, so when the skies looked clear last night I decided to invite him around to look through my telescope. He seemed pretty excited and told him it'd be ready in about half an hour. I got the scope set up, collimated, finders aligned and tested the sky a bit. Transparency was good as M42 was clearly visible despite it not being dark yet (8:45) and the half moon. I checked the moon out and saw that (although tube currents were still fairly strong) seeing was above average. Looks good so f

  2. Hi, Tried to image my favourite globular cluster. Turned out not too bad! Only took umpteen tries to get the colour right, or should I say close. I remember seeing this through my mate's 14 dob at a dark site once, could not stop saying "oh wow", looks so much better than in my 8" LX90. http://www.pbase.com/grahammeyer/image/167207230 Details under image and you can use the size buttons at the bottom also. Thanks for looking.

  3. Got up around 4.00 with the intention first of finding NGC 2146 and it’s supernova with the Dob but failed. The skies were slightly milky and it was not showing up. So, up to my rooftop perch and the Ioptron/Tak combination for the planets. Jupiter was showing bright and looked really good with lots of detail in the belts. I went back to it over a couple of hours and watched the Great Red Spot come around from the limb to the centre of the disc. Seeing deteriorated a bit but the spot was clear in moments of good seeing. It looked dark red but smaller than it has been and surrounded by mor

  4. Not a fan , but by accident I put a 6mm ep in the Barlow getting a close x400 view of the Alpine Valley . Scanned up and down to the straight wall, some beautiful clear and super stable views as I backed off to x120-x150. Hope that others found these views , high and very clear. Not a night for galaxies , so revisited the binaries of Coma Berenices . Including the spectacular colourful showpiece 24 Comae Berenice's and 2 Com.Ber. Small sleep , waking at 2.30 and out to the moon low in the west with Leo head down , tail up ! The line from Arcturus to Vega showed Hercules and the arc o

  6. Took my youngest out this evening and showed her the moon and Venus through the dob. I don’t get the kids out enough with the scope really but it’s always nice when I do. They’re always fascinated with what they can see. The older two enjoyed pushing the magnification up. We went up to 300x, barlowing the 8mm BST. Held up pretty well. I also had my binoculars out trying to spot Mercury. The three year old amused me by appearing next to me with her fisher price binoculars. Hopefully they’ll all grow up with the habit of looking up!

  9. M94 - another beauty of a galaxy, but tricky to process because of the high dynamic range. The core is intensely bright whereas the outer parts lurk just above the noise level - so I grabbed lots of luminance. 52x600s luminance and 20x300s for each RGB channel. Captured on the TMB in Spain - I would have found this impossible from west London! Comments and suggestion as always most welcome.

  10. Date: Sat 24, Sun 25 March Location: Breamish Valley, Northumberland Instrument: 200mm F6 Dobsonian Ave SQM (L) reading taken between 2.45 to 3am: 21.52 The valley was fairly lit up by moonlight as I established my equipment, long shadows were cast by myself and the scope, the moon reflected in the car window as though a head light was approaching. There was also a cold gust funnelling through from the west. This was just fine as my approach tonight and in the early hours of the morning, was for emerging Easterly constellations of Bootes, Canes Venatici, Coma Berenices, Her

So after getting my first scope yesterday a second hand meade etx90 i set it up last night only to be thwarted by cloud so i had plans for tonight then my daughter and her chap turn up by the time they left i had little time left so i just dashed outside threw the scope on its mount used the red dot sighting scope to line up on the moon OMG i swear i saw the soup dragon and an American flag .......ok im getting giddy but i am buzzing i then noticed a quite bright star in the sky so had a look at that i had no idea what i was looking at but when i came in i looked it up on stellarium turns out

  12. Another planetary imaging session, this time with the C8 and the ASI120MC camera. This was the first time I tried to image these with the C8 so something of a 'test'. The log shows that I spent 25 minutes of valuable time in taking the rig down after imaging Jupiter and setting it up in a different position to image the other two planets. Next time I'll put it in a different position that will avoid having to move it. The altitude of Jupiter was about 20 deg, and the other two at around a roof-skimming 10 deg. Unsurprisingly (or otherwise) the results seem a bit better than with the 12

  13. Staying in mid Wales and the night sky is beautiful, clear last night and even with a very bright moon, it was still better than my light polluted skies in East Yorkshire. I walked down the farm track away from the barn we are staying in with the aim of getting some nice widefield shots to produce star trails over the buildings and hillside (I will post when back home and processed). I found a spot and set the camera going, one problem was I accidentally moved it ever so slightly while reviewing so not sure how complete the trails will be. I'll have about 40 x 15 seconds in one position a

It´s been a while and the season is soon over but last weekend I pulled myself together for some astroscaping After 4 hours in -12 degrees Celsius I couldn´t feel my toes Hurt like crazy when I got them warmed up again. This is a composite image, since I used tracking. Sky: 120 seconds at ISO 1600. Foreground: 60 seconds at ISO 3200. Samyang 24/1.4 @f/2.8 Canon EOS 6D AstroTrac TT320X-AG Hope you like it!

  19. As mentioned previously, I did try a sequence of prominence frames with the intention of producing an animation. Using just the "automatic" sharpening of AS!2, here is 1hr (11:15 --> 12:15) compressed into approx. 1 sec animation! Noticed that SEEING (inferred by AS!2 plot) varied significantly over the hour... From "not bad" to "fairly naff"? Now wondering if I have to take a sequence of frames sets on every occasion?! lol. That said, I sense there were USUAL signs: Lessening of cirrus/contrails & increasing fluffy cumulus against a bluer sky!

  20. Always though the stars were bigger than just one country - don't get why a programme on astronomy has to be filmed in the UK to be of interest. As for the different mythology of the constellations I really liked hearing about the Aboriginal stories of the constellations. One of the books I gave my daughter was on constellation mythology and the different stories from different cultures is fascinating. To be honest, I think the BBC should be congratulated on this move, last year's event was a huge success; I'd like them to do one from the USA as well or one of the high desert areas in south

  21. I would settle for "Stargazing Not Live" as long as it was recorded genuine live stargazing at the time. Surely there would be some clear sky somewhere during the month.

  22. As unlikely ever to go to the Southern Hemisphere, it will be an interesting programme. Suppose every nature programme stuck strictly to familiar boundaries?! Why should stargazing be confined to the north any more than others? What we want are just more astronomy related broadcasts. Period.

  23. I had a short session early evening yesterday with the 16" SCT, before shutting down, on a whim, I popped my Denk binoviewer in with a pair of WO 20mm eyepieces. Although I should know better by now I was astonished by the difference in the view, it was like the difference between real life and just a picture, amazing contrast and 3D effect. @ MikeDnight, couldn't see the Alpine Valley central rille, I really must get one of these small Taks as an extra finder.

  24. Hi all With the first quarter moon calling, I got out the 127mm Mak and set out for an observing session. I am completing the Astronomy League's Lunar II list and when I had ticked out my targets I got out the William Optics binoviewers and set out on part two of the evenings observations. I am a new convert to binoviewing and let me start off by saying, I will never go back to mono viewing again. There is so much that binoviewing has to offer, the 3-D effect is stunning, more details are visible, smaller features come into view and when using two eyes there is no eyestrain or tirednes

  25. I have started making changes to my eyepiece collection! Having sold some fantastic "modern" eyepieces (Televue Delos) recently, the postman has delivered me a couple of "old men", the Televue 55mm Plossl & Televue Panoptic 27mm (seen pictured with the Televue Panoptic 35mm that I acquired a couple of weeks back). These "old dudes" are about to "have their day" once again when I get up & running with "Night Vision" later in the year... - the 55mm plossl will act as a 0.5x reducer (speeding up big dob to f1.9) - the 35mm Panoptic will act as a 0.7x reducer (spee

  28. Finally managed to get my star adventurer up and running and got a camera on it. What has become immediately apparent is that I have no idea what I’m doing! But first attempt has been a lot of fun. Being a visual observer, I can set up a mount, and being a semi average photographer, I can set up a dslr. After that it all goes a bit wrong. Managed to get deep sky stacker to do.., something... but was left with an essentially white image. After some serious serious bar sliding in Lightroom, I managed to get something resembling what I took! Problem is I think it’s less interesting than the indiv

  31. I've had a fruitful weekend: good seeing (for 90 mm aperture, that is), crystal clear skies on Friday, and equally good seeing on Saturday with 1/3 cloud cover miraculously sweeping sideways from my location since morning to 4 pm. Too bad I caught only one stronger C-class flare in AR 2661 in all those hours. Everything captured with a 90 mm refractor with Lunt 50 etalon, PGR Chameleon 3 mono (ICX445), processed with Stackistry and ImPPG, showing AR 2661. Overview shot of AR 2661 on Friday morning: Friday, 30-s intervals, 0:53 h and 1:06 h. Lots of small-scale activity,

  32. With the moon available to do some test shots with my ZWO ASI 120MC fitted for the first time to my Celestron 4SE on the goto mount, I managed a couple of half decent images. Scope wasn’t really cooled down fully, and seeing was a little iffy, so here are two of the best shots I got so far from earlier on about 7:30pm onwards. Couldn’t get focus as good as I could on my 120mm ‘frac, but pretty close I think. Mare Crisium area; Clavious region; Stacked in Registax, processed in PS.

  35. Finally after weeks of it being overcast, had some clear sky last night, so I took a few shots of the half moon and Orion. Just some quick single shots as its still bitterly cold and I've got a bit of the flu, so wasn't feeling up to sitting outside and getting a lot of frames. As always, feedback and tips/suggestions are welcome and appreciated. Half Moon - Canon 60D, 200mm focal length, ISO 400, F35, 1.6 second exposure, RAW processed in Photoshop. I'm pleased with the contrast in this image, although I was hoping for a bit more detail, and its a touch soft. I think I was

  36. One big and spectacular view this one; it really shines out under a dark sky. I just needed to sketch this one. The bright core stands out, not evenly shaped, it is a liitle bit tapered on one side. On the upper part, a dark lane is clearly visible in the center, especially at the core.

  37. Strewth Bruce! Maybe the lovely UK weather has put them off. Let's be honest, stargazing in Blighty isn't an easy task? Cloud, rain, wind, light pollution.... If the BBC can influence the public on the effects of light pollution like they did with the plastics-in the-seas , wouldn't that be great? Looking forward to seeing skies down under...

  38. Thanks all - here he is a few weeks ago having been dug out of his house. His house is subjected to something called the Helm Wind which has to be experienced to be believed! In fact the wind is probably as much of a consideration as the rain here. I just want to be able to make the most of the opportunity I have while I live here. Ideally I'd like a 12" scope solid tube too, as 14" would put the eyepiece frustratingly high for someone just a smidge under 5ft 8" and it seems to me there's more structural stability to hold collimation. Great idea about raising it up too - I could do

  41. Hi everyone. Since we bought the scope we’ve had pretty bad weather and the moon has only been out at a reasonable hour twice so we haven’t had much practice yet, all up probably two hours. We’ve had a fair bit of trouble getting our alignment and tracking set up. But tonight I did manage to find the Orion Nebula. It looked like grey smoke in the eye piece so we hooked up the camera and took a few pics. We didn’t have a lot of time so we just played around with the iso and the exposure times as best we could. Here is a picture of the moon that we took and a few of the Orion Nebula (our f

  43. I spent a few hours out yesterday afternoon and early evening shooting at the Moon, initially through gaps in the clouds until it cleared later. The blue sky Moon is a composite of an ASI120MM-S mono mosaic at 1 metre focal length with Astronomik 742nm IR Pass filter, with Nikon D3200 DSLR colour data at 2 metres focal length. The close up images are from the ASI with focal lengths ranging from 3.5 to 4.5 metres. Seeing wasn't great, but that's normal around here!

  44. Wasn't planning to go out tonight, but I found this https://www.aavso.org/aavso-alert-notice-626, so I took the scope out to see if I could find the star t1 Carinae (HD 92063) where the nova was supposed to be. Took me quite a while, I was going back and forth from the scope to a stellarium screenshot, thought I found it like 4 times but I was wrong. Finally found it, it was pretty hard because there are so many stars in that area, but the stars patterns around it matched my screenshot 100%. Don't know if I saw the nova (wasn't sure what to look for) but I was still so happy I could find the s

  46. Hello everyone I've been out for just over two hours tonight. The main purpose of tonight was to give my Vixen Orion P-80L a run through its paces, as it was out of collimation last time I used the telescope. It is now perfectly collimated. One of the other reasons for observing was also to compare my 7.7mm 365 Astronomy Abbe Orthoscopic eyepiece, 8mm Brandon eyepiece, and Baader Hyperion Zoom eyepiece. I also compare my 6mm Circle T Orthoscopic eyepiece to my 6mm Japanese Huygens eyepiece (0.965"). Well I used what I believe to be the Plato crater for my comparisons. What can I say,

I've spent a couple of hours scouting around the moon using my binoviewer and various eyepieces. I've seen hints of the central rille along the Alpine Valley and made yet another observational sketch of Werner. I also spent some time playing with mono viewing using TV plossls, Vixen LV's and a few ortho's. Even with the binoviewer I observed using a pair of TV 15mm plossls and 15mm LV's, taking time to try and ass
