  1. With today's forecast looking like solid overcast all day, I'm fairly confident I'm not going to be able to replace the cloud at the end of my chart with a Moon image. This was started on the Saturday evening of the Sunderland Astro Jupiter Nights event ( Jan 24th ). It's not a bad record for two weeks and only missing two days. I'll keep going over the next two weeks ( when the Moon is visible ) and see how I can do in a Month. Considering UK weather patterns, I'm surprised I've done this well so far. The original image is 10500 x 3000 pixels.

  2. Finally clear sky no moon.... Quick I have till moonrise at 8pm. At 7.10 I located and sketched NGC 2534 in Lynx....basically left of Caster and Pollux. A faint one for a starter but it was pretty easy with averted vision in my new WO 7mm eyepiece..boy this is a keeper galaxy seeker eyepiece. Then at 7.25 I picked up the brighter but still small edge on NGC 2481 in Gemini itself just below and left of Caster and Pollux....Just think of all those folks looking at the eskimo nebula and missing this little gem.. 7.35 and on to NGC 2350 below Gemini..A very low surface brightness one this.

  3. Was going over old unfinished images last night so thought I would try a mosaic out of three of them. I have not added all my usual info on this one, as there are other images of mine which have all of that information. Thanks for looking.

  4. So tonight i dunno what was different but i managed to get 35 100s exposures of M81 and m82. Took me longer to find them than image them but now i know where they are so im cool. Really pleased at how they turned out for a first attempt. Ive been banging my head a against a brick wall with andromeda all week. Managed to catch the exposures at iso800 at 100 seconds each. so 35 x 100s 25 darks 25 flats(laptop/notepad/paper method) 25 bias Gradient xterminator and PS curves. First go also got lucky and caught love joy as well... Only 5 60 sec exposures as the clouds started rolling

  5. In this photo large angle of the eastern part of the Mare Frigoris, this region that has great merit formations such as craters, Aristoteles, Eudoxus and Burg among others, what really caught my attention was a so-called training "Pyroclastic Eastern Mare Frigoris West" .For those who are not used to research and deeper observations, she probably would despercebida.Vejam to my idea here is just to draw attention to those formations that may not be as impactful as the aforementioned craters, but can generate large research interesse.Um place with pyroclasticos deposits is automatically a place

  6. Orion & Running man Nebula. Spent a long time getting to this stage. It is made up of 17x180,20x120,27x60,20x30,20x15 second exposures, Canon 1100D CLS CCD filter & Tv 85 refractor. First real attempt now I'm understanding photoshop a little bit now. Only learnt last night how to overlay two different images, which is one reason I haven't tried before, quite happy with the way it's turned out

  8. Just received my new pair of 18mm BCOs from FLO and amazingly it went really clear tonight after a dull and damp day.. I viewed Comet Lovejoy, M42 and Jupiter over a one hour session from 7.30 to 8.30pm, before the clouds rolled in. The Moon was rising in the east but quite low and not as yet too bright. All objects were viewed with the BCO's in my Maxbright bv's and 5" D&G F15 refractor aka "Andromeda". Comet Lovejoy. I found this first with my Nikon Aculon 8x42 binoculars close to Almach in Andromeda (quite apt!:-).. ,it looked rather like M13,through a 4" scope at low power, ie a small

  11. Sure this has been done before. I borrowed a 1.25" 13nm filter and got it as close to the sensor as possible in my 1100D. There is vignetting and I couldn't use my flattener in my TV85, so this is a test image just to see if it's worth investing in HA. It's just 6x600 s stacked without any calibration frames. Second attempt at processing and quite happy with the way it's going. Any suggestions welcomed. I'm thinking the Baader 7nm might be better and cheaper in 2" format

  12. Out again tonight for the first time without the moon. Had a look at a number of galaxies. I managed to see a galaxy NGC 2767 which is m13.8 and a star near NGC 2350 which was mag 15.0 and that was at an elevation of 36 degrees above the horizon so there is potential to go deeper still. So to sum up the mirrors have now equalled my record with my 14 inch and gone 0.3m deeper than the 16 inch before the mirrors were coated and I think at a higher elevation might get to mag 15.2 ish. The coating of both mirrors has added 0.5 magnitude which given that magnitude is a 1/5 of a logarithmic scale is

  13. RED ALERT! RED ALERT! Get that sorted now! The stars will always be there. The planets, too (although maybe in different ways). Your wife is more important than all that 'in the sky' stuff. And don't you forget it, sir! (Now, it's looking clear outside; she's into her book; maybe I can sneak outside for a bit .....)

  14. Had a decent run this week. With sun most days! As usual I was using my 120mm f5 Skywatcher achromat with Lunt wedge, Baader SC/ND3.0/Polarizing filter and Pentax 6.5-19.5 zoom.

  15. Had same issues with the images last night... Met up with a member of one of the local astro groups and tested out his 8300, worked like a champ. Celestron gave me good news though, they are gonna honor the warranty and swap it out for me without me having to send it back to the original owner first. Small blessings.

  17. Probably my fourth time observing now, wanted to have a quick look at jupiter, then wanted to try and find the andromeda Galaxy for the first time, then wanted to spot the Orion nubulae for the first time.. These were my objectives for this evening.. Well had a good look at Jupiter was fantastic as usual so spent quite a while gazing at that. Then tried to find the andromeda Galaxy, almost gave up, but eventually found it. Wow. Spent a while gazing at that also. Then tried tried to pick out the orion nubulae, was easier to find and again another wow, so spent a while gazing at that too.

  19. So I was going to try and image the partial eclipse in March through its various stages and decided therefore to build a Solar Filter for my DSLR. Anyway, finally got it all together today and with a lovely clear day managed to get a great view of the sun in my 55-250mm Lens. I was pretty happy that I managed to actually pick up the sun spot regions as well. I am tempted to use the rest of my Baader film to make a filter for my Mak.

  20. The pre-dawn sky was very clear on the morning of Wednesday 4th February, and I was able to watch moonset during the course of my journey into work, with bright Jupiter hovering like a beacon about five degrees above the Moon. It was quite a spectacular sight, as mid-way through my journey the Moon had dipped just below a woodland hillside, away in the distance. The sky immediately above the hillside appeared bathed in Moonlight, and made for a very picturesque view. Jupiter was still visible, beginning to hug the horizon, embedded within the moonlight. There seem to have been quite a few oppo

  24. You are right that it is a test of conditions. Always prior to attempting the Horsehead, I "consult" with the Flame to decide if the effort is worth it! Well, as they say, dark skies are the most critical aspect of viewing the Flame or pretty much anything. I was able to see both lobes of the flame with my TS 50mm f6.6 ED refractor with relative ease from my preferred winter dark site. SQM readings typically above 21, so pretty dark I would say. Lately I am getting into orthoscopics and I have had very good results with a Fujiyama 18mm and generally use 18mm and 21mm eyepieces on the Flame and

  25. The only thing I had to take a pic of the Moon with its halo and Jupiter was my old Panasonic Lumix. I was too pooped to resurrect my 40D! It's grainy and not brilliant but at least I caught it. I should have done a shot to get the Moon's detail and PS'd it in, but that might well have looked fake. Alexxx

  27. Hell Matt, Welcome to the world of video astronomy Your story is a carbon copy of mine so no point in repeating it but let me help if I can. In my opinion, a good camera to get you started and to suit the requirement you mention would be the Samsung SCB-2000. This camera will amaze you trust me and can be picked up if you search well for a bargain. I saw one sell recently on Ebay for £21! Anyway, I will go into more detail later but for now here is an image from a recent broadcast I did with the Sammy on M42: Also, just to say I may be broadcasting again tonight weather permitting so

  28. I'm Stepping beyond and for about 2 yrs. l finally had my dream come true after so many failed attempts. I first was using a Z10 dobsonian {fail} , then a lil eq80 refractor on a eq1 mount {fail} and once I got my Black Widow 8 in. astrograph on my used lxd55 mount "SUCCESS WOOHOO" ! 2yrs. of using my 1 good hand and failure after failure, I got Jupiter on my laptop screen. My disabilities hold me back from doing a lot but, I can show my grandson what grandpa sees with his scope and teach him about astronomy .

  29. Dear All A confession...as much as I enjoy stargazing with my CPC925 - especially planetary observing - DSOs can be a distinctly underwhelming experience from my suburban skies in South England. I suppose that's the beauty of GOTO 'scopes - you quickly move on to something else. The trouble is, I still want to be blown away with what DSOs I can see on a good night. But I'm not. There - I've said it! So...I've stumbled upon your Video Astro forum and have reached the conclusion that using a video camera might just might help to manage my expectations, i.e. more comfortable viewing (equals l

  30. Heres Another from Feb, Again Juniors white centre is clearly resolved. For our conditions that is. I have just finished making my larger fans for the skywatcher. Not sure I can get it to perform like I did last year, But the scope has not been cooling well. these should help Its interesting doing red animations, it highlights which colour runs are worth working with. This was one of them The green channel looked nearly as good as the red. Though the blue was still dire. seeing may have worsened on that,

  31. Frustrating night yesterday, only 1 image run in around 2-3 hours so much cloud despite the clear forecast. The usual set up C9.25/ASI120mm 4,000 frames @ R,G and 3,000 @ B. Aligned in PIPP and stacked in A/S. Shame about the cloud the seeing was quite good while it was clear. Nice to catch another one of the transits though

  33. It seems Amazon are asking a bit much there, although I have to say its worth every penny. However, the reprint can still be bought for around twenty dollars, which will likely be around the same in pounds, through Sky Publishing. I think the Amazon prices must be for the original 1965 edition. It is also available on line as a free download. Mike :-)

  39. Bring what you can easilty fit in Stu. I mostly just bring one scope although I could fit them all in my caravan. Lucksall owes me some clear skies, my past 3 visits have resulted in about 30 mins of observing If we do get a clear dark night I suspect you will kick yourself if you have not got aperture with you though.

  40. Paul, I had a good look at the flame nebula the other night with the 12 inch and made up my mind the eyepiece I was using was alright but the scope could do with being half a meter larger . Alan

  41. That is exactly right! 2500 is CPR, counts per revolution. S6 encoders have a quadrature output: there are two signals that have a 90 degrees phase shift. Each of the output generates 2500 impulses per revolution. DSCs read the state of each output and count both rising edges and falling edges of the each signal thus registering 5000 changes per rotation for each output. Because the two outputs have a 90 degrees phase shift that gives us 5000 x 2 = 10000 steps per revolution.

  42. Thanks guys, it was just so good to get a really clear sky for once. I really am delighted with these Baader's . I didn't talk about the mechanics of the BCOs as these were covered in some detail in John's original review. I didn't mention that I also had a quick peek at the Pleiades too..couldn't fit them all in of course at 18 mm (or 25mm plossls) but the contrast of the pin sharp stars against a dark sky (and remember the Moon was still brighr) was very impressive..and the Zeiss 85deg got most of the cluster in . I've managed to find a pair of the 10mm BCOs as well, in mint, like new, c

  43. We were just talking about this in the pub afterwards Leigh, and there is no reason why you couldn't do this. Let us know if it works Great talk indeed Kieran well done! Now we all have to save up for more kit Great to meet you and your daughter Dave glad you brought her along, sorry didn't get time to chat, but I am sure we will at another meeting soon. Nice to see so many new faces as well was a very good turn out.

I will definitely come to you for advice before I invest in photographic equipment. David, it was good to finally meet you and your daughter. Hope she found it interesting. The evening went so fast, it's a shame we didn't get much time to speak to you both a bit more. Me and Luke have just come back in after a fabulous hour (or so) viewing in the back garden. Jupiter is stunning this evening, and we even manage
