  1. A planetary nebula in the constellation of Cygnus - close to the Crescent Nebula. Only relatively recently discovered (2007) because of its extreme faintness hidden in bright hydrogen clouds. Also known as PN G75.5+1.7 43 hours total integration, captured from Extramadura, Spain. Scopes: APM TMB 152 F8 LZOS Mount: 10Micron GM2000 HPS Cameras: QSI 6120wsg8 APM TMB 152 F8 LZOS, 10 Micron GM2000HPS, QSI6120ws8

  3. Hi all - checking in for the first time in ages...seems I last posted images on April 4th this year although I have made the odd comment in other folks' threads in the meantime: plenty of images since then, too many to post here tbh but I thought it worthwhile to concentrate upon those we obtained over 4 nights in late June at Natimuk in the west Wimmera region of Victoria...a quick (400km) trip there at the time because the GFS predicted a hole in the wall-to-wall carpet of clouds engulfing South Australia at the time. (not much has changed since, being honest! ) Anyway, the forecast we

  4. This is 93mins of 3 min subs on 3 nights, all the 3's. Conditions varied a fair bit and last night was by far the best but was using gap in the trees time for M17, which I will add to further. It is nowhere near as good as the shot from a member the other day from similar latitude but he had a F/L advantage over me of about 400mm. Same old gear at the moment Canon 40D modded, and 805mm APO on AZ EQ 6. Spent what seemed an age getting PA back to something like only to kick the tripod, yet again whilst putting the roof back in place, life! Please feel free to offer

  5. Too large in file-sizing to post all images in a single post...here are the individual rgb's with their accompanying individual channels...of the 4 nights the 23rd was the poorest but still quite acceptable. Some nice blue channels reflecting the seeing btw.

  6. My little astro group (Walton Astro Group) met up on the Green near Esher on 16th July to try to catch the partial eclipse. We arrived at around 9pm and set up where we hoped the Moon would clear the trees first. We were a little bit out but overall were probably in the best place for the whole evening. The Moon rose into view at around 10pm and we had a clear view right through until after midnight, apart from some small clouds which actually added to the atmosphere. There were seven of us in the end (EDIT eight, I can't count!), with six scopes between us. 10" f6.4 home built dob

  7. I received my new ioptron cem 40 mount yesterday from First light Optics. Excellent service and advice from them, thank you guys I was lucky to try it out last night , first the ipolar, it worked a treat was polar aligned in less than 5 minutes, and it was a quick alignment as I did not get the crosshair in the middle of the circle. however I was 3.7 arc minutes within the pole. the clouds started to roll in a little, so I fired up PHD2 and tried guiding, the rms values were 0.07 RA and 0.28 DEC. im sure I can improve on that especially if I use guise assistant and get a better polar

  8. This is one of my first tries at Milky Way wide field. The aim is to cover this area at high(er) resolution over the summer/years. For now, last night, I managed to shoot a bit over 1h with 2 Canons. 50mm @F/2.8 with the 550D and 70mm @F/4 with the 6D. Here it is:

  9. Put alarm on at 2am, out observing 2.20am to 3.35am. Excellent views at first, surprising good for such a warm night, excellent in binoviewer at x150 with 24mm Orthos. Started to get thick hazy clouds interrupting later which really affected the image. There was also a lot of moisture in the end, the outside of the scope was awash with moisture by the time I got in. Still some excellent views early as I said, and very enjoyable. Also managed to take some snaps, using the SW 120ED. The pic below is a single frame, Olympus E-M5 Mk 11 giving an effective focal length of 1800mm, 1/400 sec,

  12. As I had proposed, following is a photo indicating the landing site of Apollo 12 and 14. As the landing sites were close it was possible to indicate both locations with a single photo. So, only in the growing phase and thanking them for their luck, I was able to photograph the landing sites of the 6 missions to commemorate the 50th anniversary of man's arrival on the moon. https://www.astrobin.com/full/416710/0/?nc=user

  14. This book is available now in some branches of Works, at any rate it's in the Keighley store. I have many of the Haynes Space/Astronomy series of Haynes Manuals I have bought at a bargain price at Works and this is a good one, if you have any interest in the Moon and Apollo go and get it before they sell out. This one is a good one and one I have been hoping for some time they would stock, didn't want to pay £22! Link to Amazon below so you can read more about it. https://www.amazon.co.uk/Moon-Manual-Owners-Workshop-Haynes/dp/0857338269/ref=sr_1_3?keywords=moon+haynes+manual&qi

  16. I've been contemplating a Todmorden Pier for a while and got the green light from Mrs AdeKing..... But the only place that got approval was the NW corner of the garden. I set up to observe Jupiter from there the other night and its an awful position as the view approaching the meridian is over the Summerhouse which gives off heat like there is no tomorrow, My thought was that I'd observe more because the mount would be permanently set up, but the reality is that the seeing is so bad as to make it a non-starter. But in the words of Baldrick "I have a cunning plan" in that we'r

  19. Two adjustable shelves added to take gear. The plastic bulk pet food container carries two Maplin 7Amp regulated PSU's with 12 VDC feed cables to various pieces of kit (4 available) - the PSU's sit on hanging shelves below the top plate. An anti-surge mains sockets for smaller adapters all housed in the moveable container. I was going to break this down and put the PSU's on shelving but with the small obsy space decided I would keep the mobile as they were when using the iEQ45 Pro outside on the patio. The Tosh laptop will sit on a shelf to the upper left of the photo.

  21. Well a big update and milestone. Today I finished off painting with only a small number of touch ups needing to be done. I have found a long term solution to solve the issue with the rollers but I can live with it until then. The outside shell is now complete, electric and ethernet wires have been run as far as the obsy and just need connecting at both ends. The inside is still a little rough but I have put a single sheet of osb up for now to be able to mount the monitor, the rest will be done on my next days off. The next few days will be sorting the PC out after work as it will

  24. I agree with the idea of leaving a fan on to break up the air above the mirror... you can switch the fan off and watch how the image quality changes without it. I've read of some scopes having fans blowing across the face of the primary for this reason. I also wonder whether option 4 secondary issues could still be a contender if the figure of the secondary may vary with temperature or rate of change of temperature.

  28. I'd go for a pier every time. When I bought my rigel pier to replace the Skywatcher HEQ5 tripod the improvement was immediate. OK, I'm an imager so the rigidity requirements might not be a stringent, but not having three legs to kick out of alignment , or trip over in the dark, was a big bonus.

  30. If you kick a pier, it hurts. If you kick a tripod (which is easily done) you've lost any alignment you've had. You'll probably swear more in the latter case than the former. If you don't need to move the mount round, I'd go for a pier every time.

  33. I guess that storage depends on the camper. A typical panel van conversion (PVC) might have an issue, but this probably isn't the case with most coachbuilts and A-classes. We're lucky as two of us rattle around in a 7m coachbuilt. However, even with a PVC, you can load up the habitation area with mount, scopes, and accessories as they'll be outside the van once you're set up on site, and can be stored in the front of the van when you're not doing astro and want to use the habitation area. That said, I agree about the binos -- we keep a pair of 8x50's in the van. We often also take an ST80 with

  35. indeed, almost everything I do in PI I merge back with a 'before' version, experimenting with the opacity to suit. Saved process icon for it, but would be nice if they actually formalised a tool, real time sliders etc - but then it gets too much like PS for their tastes

  36. FWIW we use our campervan as a mobile observatory. The camper is nice and warm inside and has a reasonable supply of 12v electricity. So the mount and telescope go outside in the cold and a couple of cables connect that to a laptop inside the van. Once the rig is set up, we can come in from the cold and spend the night imaging in the warm. Even if you only want to do visual obs now and/or your budget doesn't run to imaging, you might want to consider the comfort that a camper can provide and buy equipment that can be used or upgraded for imaging later.

  37. I am not great with camera lens imaging, but this target is too big for my scopes anyway, too low in the UK so no choice but to do it with a camera lens on holiday in Spain.I imaged this 2 years ago from the same location with my DSLR, but this time I took my Atik460EX to capture it in luminance to add to the colour from the DSLR image.This is the original DSLR image from 2017https://www.astrobin.com/full/300756/D/Using only an ioptron Skytracker and having Bortle 5 skies and a nifty 50 lens this is probably the best I can do with my kit and skills.Taken over 2 different holidays in Spain:DSLR

I'm amazed that Darryl drives 400km to do this, though. I'm reminded of the "Hitchhiker's Guide" quote: "You may think it's a long way down the road to the chemist's, but that's just peanuts to Australians" Something like that, anyhow James

  43. Focuser mod to the Bresser 127 mak While I find the focuser works well I didn’t like the slop in the shaft and the knob wasn’t the best either. There is no bearing where the shaft passes through the hole in the rear cover so the shaft does flop around quite a bit so I decided to fit a bearing. Got a suitable flanged ball raced bearing that would fit the shaft. Drilled out the hole in the cover to 12mm and then filed it out nearly to the bearing diameter of 12.65mm making sure it would be a tight press fit. Decided to fit the rubber knob cover off the Skymax 180. Found a 14mm diameter moto

  44. Got the Trius back yesterday, so put it back on the 'scope. Did have to move the 130 apo forward in its rings to clear the box so rebalanced by moving the 80mm f/4.4 back and bolting some big washers onto it. RA balance looks to be spot on now, but the dec is still a bit out. No USB problems yet, so it might have been the old LT. Now waiting for the next clear night to test everything.

  45. Greetings everyone ! I'm new to astrophotography - but not new to photography or astronomy. My father started teaching me fundamentals when I was in my early teens, and also started my interest in astronomy by frequently taking the family up to Mount Palomar (we lived in San Diego at the time). Getting into astrophotography, as I get close to retiring from engineering, is allowing me to bring the two hobbies into one. My wife has been very supportive of this adventure - she started Grandpa's Telescope Fund several years ago which made shopping for me on birthdays, Fathers Day, and Christ

  46. Thanks. I have placed a 'donut' on the primary and done a bit of basic collimation. I also got rid of the erecting prism on the 20mm so its improved a little bit. I took a punt and procured a Svbony 23mm and that has opened a better vista for me. Now contemplating purchasing a Skywatcher Planetary UWA eyepiece 4 or 6mm and the Baader barlow.

  47. Would a pair of 15x70 or 20x80 binoculars be easier to stash away in the camper? I left a pair of Celestron 15x70's in our Bongo when we had it. Very capable under dark skies. Although i always wished i had a scope with me. A Skywatcher Startravel 102 or 120 on an AZ4 would have been fun but my wife would have done her nut. Surprisingly very little space in a camper when going away. Binoculars were the limit i found.
