    Low Level aircraft - Mach Loop - Wales

    For the past year or so we've been making some regular visits over to an area in Wales (Snowdonia National Park) known as the 'Mach Loop' It's an area used by UK and US military aircraft for low level training. A quick climb us some of the hills and you can be level with, or above, the jets as they come through at speed well in excess of 500mph. Camera: EOS 750D Lens: Sigma 150-600mm When the aircraft don't come through the scenery is amazing, peaceful, quiet and I love it! The place also has some very dark skies (although some restricted views E & W!) which I intend to make full use of. The view to the S/SW They when they do come through ..... USAF F-15E 48th Fighter Wing F-15 close up of the cockpit - not a bad day job RAF Tornado - sadly all now retired Not just the jets .... the bigger transports turn up for a go RAF A400M And the smaller jet and prop trainers I should be back there in another 2 or 3 weeks.

    My little friends.

    A few pictures of the little ones. Mum has been bringing up four youngsters this year. They are growing so fast. A couple of weeks ago they looked like mice running about my lawn. Mum is very camera shy and is off as soon as the camera tries to focus but the little ones are totally un phased.

    Maybe I spoke too soon, a bit of decent seeing and things improve. Or maybe forget the colour cam and go for IR filters is the way to go. I have more data to prod and poke but am in need of sleep. 200mm SCT x2.5 powermate IR642 filter Chameleon mono cam.

    Hi folks. I came across this online this evening..... Its an interactive atlas of all the Solar Systems many moons. Lots of info and good visuals to keep you busy for hours on a cloudy night. Be warned.....its no 10min read through......when you get to Jupiter, things start getting rather complex ! πŸ˜€ Well worth a look.... https://www.nationalgeographic.com/science/2019/07/the-atlas-of-moons/?utm_source=digg&utm_medium=email

    Hi everyone - this one gave me a bit of bother I don't mind saying. A lot of contrast of dust and nebulosity. Just over 2 hrs of data on a non-too-good seeing night. Might give this one another go towards the end of summer

    Soon be time to say good-bye.

    Well its been an interesting few weeks to say the least having this character around. He has taken over my obs, my garden and pretty much my house as well. Not to mention most of my waking hours. But my goal has always been to get him fit and well and then back to the wild. He has made a remarkable recovery. His injuries were far worse than I had first suspected as it transpires he is now totally blind in his left eye due to the head injuries he suffered. Not that this seems to phase him much. Well today he made his first real attempt at flying. He has been working up to this for a few days now with various attempts and exercise routines. The bottom corner of the garden was probably not the brightest place in the garden to attempt this but there you go. Prepare for lift Off. Gaining Altitude. Left Turn ahead. Emergency Left Turn !!!!!!! The Landing. Doesn't he look pleased with himself. My guess is it will soon be time to say good-bye. That is if he can ever drag himself away from the food bowl πŸ˜‚ .

    Baader ClickLock 2" DiElectric

    I just couldn't resist it. I'd been looking at this for ages. The clicklock is very good although I'm not so sure about the nose-piece safety smurfs, sorry, kerfs. I could probably swap the nose with an older Baader version. It weighs about the same as my 2" Altair dielectric with carbon fibre sides. Indoor tests seem to indicate the safety barfs aren't as ineffective as I'd assumed. Unlike the click locks on my other 2" diagonals this holds the 19mm Luminos. Unfortunately the blanket cloud over most of the Midlands will not allow me to outdoor test it any time soon.

    You are quite right Phil. I do have one saving grace and that is the Mum never leaves, she has been here for years rearing her young. When she hasn't got little ones she is quiet sociable. I will often find her inside my house when I am up all night with the door open.

    Another Dob-Mod Thread.......

    Ok, after a 6 month layoff, its time to continue with this 'Dob-mod thread'. I have decided to upgrade the standard aluminium tube that the scope arrived in, to a carbon fibre version. I have sourced a supplier, in Germany, and will be ordering the tube in the near future. It will come with everything prepared, all holes drilled correctly etc, so should be a straightforward 'transplant'. Once i take delivery of the new tube, i will flock it first. I will also be upgrading the Orion Optics 'spider' secondary mirror holder. I have something in mind, from the USA, and need to get that ordered as well. That leaves a cooling mod to do, and one last thing......... That one last thing is happening soon...... I have finally, after a long search, found an equatorial tracking platform for my telescope. To be continued...

    Bino Session

    A tip i learned from 'Eddgie' over on 'Cloudy Nights' : When using binoviewers with Catadioptric scopes, be it SCTs or Maksutovs, try and keep the lightpath distance ie the point from the back of your scope to your eyepieces as short as possible. With one of theses scopes, if your put a visual back, and a regular mirror diagonal, with a long nosepiece, and add something like a clicklock etc, then put a binoviewer in there with eyepiecs, you're adding way too much length to the optical lightpath. A big 2" diagonal (instead of a 1.25) is even worse due to its size and length. I'm not saying the above won't work at all, and you may even be fairly happy with the views, but your scope will no longer be working optimally at its intended aperture. I've read lots of reports over the years from observers trying bino's out with SCT/Maks saying the image is dim, not very bright, over magnified, poor contrast. Thats because it is. The blame the bino, give up on it, and go back to cyclops viewing. If you go beyond a certain length of lightpath, and i think its around 160 - 170mm (the bino itself is around 110=120mm) this is what will happen : To focus with such a long lightpath, you end up winding in the primary mirror a long way in along its travel, to a point where it gets too close to the secondary mirror, and the outer part of the primarys reflected light is clipped off and lost. This is aperture loss. It may only be a small amount (less than an inch) with a small scope, or quite a bit (2 inches) with a larger scope like a C14. So your 127mm scope is no longer a 127mm scope, but probably closer to 110mm. Its no longer the focal length it was either, but something much longer. As you increase lightpath you increase focal length too and its magnified. Your focal ratio is no longer F12 (or F15?) but something bigger. The magnification you thought your eyepieces were giving you is actually much bigger. Contrast is degraded. As you lose the outer part of your primary (the best bit) to aperture loss, your secondary mirror obstruction size, as a percentage, is increased (up past 40%) You'll also be introducing Spherical Abberation (as much as 1/5 of a wave) into your view as well, degrading the image you see still further. But, you can mitigate all of the above by keeping the lightpath to a minimum. This means : Ditching the visual back saving about 40mm of lightpath straight away. Investing in a low profile type diagonal. This couples directly to the binoviewer (assuming compatibility) at one end, and uses a short 10 or 15mm adapter to connect the diagonal straight on to the SCT thread at the back of the scope. Big 2 inch mirror diagonals with nosepieces and Clicklocks take up way too much lightpath !! Like i said, you may be happy already with the views you have and that is great. But if you want your telescope to perform optimally, as designed, to its given aperture (and who doesn't ?) then keep the lightpath as short as you can when you use a binoviewer with these type of scopes. Below is an image of my old C8 with a Baader Maxbright binoviewer in an optimal configuration. When i had it, i did an experiment an put a 2" diagonal onto the original visual back with an adapter, and then added the binoviewer, and believe me, the views were a lot dimmer, and not as contrasty as they were with the short lightpath kit on, and everything was rather precarious as well. To me, to have an 8" scope only performing as a 6.5 - 7 inch scope would be a deal breaker, knowing all the hard earned money i had invested in the scope had resulted in something that wasn't performing as it should. Hope this is of use to someone !! Comments welcome πŸ˜€

    Low Level aircraft - Mach Loop - Wales

    Thanks for the comments .... Currently the aircraft don't come through as often as they did at this time last year, but still through most days. It's like fishing .....you don't know if or when you'll get anything, but even the blank days are enjoyable. It took a while (and a new lens) before I started to get on top of the tracking needed to follow them at that distance and speed. Still not mastered it but getting better and of the images I get there are far more 'keepers' than I used to get Here's a couple of 15's for you. Not the best quality image as it was at the far end of the 600mm reach, but I love trying to catch them head on with the wingman slotting into position behind. If you do get over there give me a shout, we might be there at the same time. There is a campsite just over a mile down the road that costs Β£5 per person/night and the aircraft fly directly overhead. We had an RAF Puma helicopter pass low overhead at about 01:30 a few weeks ago - got woken up but just laughed and rolled over. Also there are times when the aircraft will NOT come through, like weekends and bank holidays. If you find the 'official government timetable' then totally ignore it, it's not even for that area! I'm lucky to be able to get over there at least once per month and even luckier that my wife likes it as much as I do. If fact, today she's suggesting we go back next week - who am I to argue! Finally, as an indication of how low they are compared to where we are on the hills Not many places where you can stand and look down on an aircraft doing over 500mph! These F-15's came through early in the morning just as we parked the car and were about to head up the hills - we walk up that slope on the left Heard them with just enough time to grab my phone. Cheers again for the comments ..... Al

    The difference between the 127mm Mak and my 102mm Mak is quite startling. I almost considered a 150mm SCT instead of the 127mm Mak as I originally intended to use it on a Porta II/Hal 130 combination. I think I'd need a JCB to mount a C11 lol.

    Bino Session

    It's big if you are partially paralysed in the right arm, hand and leg. As the AZ5 was set low it wasn't so difficult to slide the OTA into the dovetail. I'm slowly getting some dexterity and range back into my right arm and hand. I did practice a bit though, just to be on the safe side. Sitting directly behind the visual back seemed more logical than rotating the diagonal. Any OTA above 10cm is difficult to pick up with one hand. I need to utilise a large belt to get my 9.25" (235mm) Celestron Evolution SCT into its mount lol! It's precarious but I can do it. When you have a fairly severe physical disability everything is a logistics exercise. I have to plan how to carry each item of equipment out safely and then assemble it. This isn't always straightforward. As a consequence I tend to use smaller scopes a lot. The ED72 on a Porta II/Polaris tripod tends to get a lot of use. Getting the APP-TL130 back into this little bag with one good hand can be bloody frustrating though ROTFL.

    Another Dob-Mod Thread.......

    Pleased to report all is well with the encoder fitting.... They were a doddle to fit, and everything is performing well. I even had a clear sky this evening and spent an hour testing them out in my garden. Some photos of the fit.... First thing was to put the main tube to one side, as i was going to fit the azimuth encoder first. The encoder simply screws onto the existing thread of the screw that adjust azimuth movement. The end of the encoder arm slots into the small piece which is shown in the above images. This attaches securely into the fitting at the top centre of the Dob base plate. The Azimuth encoder cable is then attached. Easy so far. Onto the altitude / dec axis. The OTA was elevated so i could get at the large altitude rings. Two screws were removed an a straight section was attached with a hollow connecting pin in its centre. This is where the encoder sits. Another pin thingy was fitted below to the left of the altitude bearing where the end of the encoder arm sits. OO mounts have the necessary holes pre drilled, but this was too small so i had to drill it out a mm or so. The encoder is then fitted, and is secured underneath by a thumbscrew. Then the encoder cable is attached. This is handy, because i can't lift the whole scope in one go, its the base first then the tube, which i guess is the norm for most Dobs. Its easy for me to remove the whole encoder arm with cable attached and store it on the base plate, then when the tube is in place, simply fit the encoder arm which takes seconds. I purchased another one of those handy little shelves that attaches to the base via a small ball head. I can swap over the Nexus DSC from my DM6 mount to this Dob mount with ease. There are also settings in the Nexus' menu which caters for up to 5 different set ups. All leads are then attached, and a bit of cable tidying done to make it nice and neat. All done. Just as luck would have it the sky was clear outside. I thought i'd try it out and after the 2 star alignment everything worked ! ? I used my new illuminated reticle eyepiece to centre the alignment stars (Betelgeuse and Castor) I then ran off about 10 Messiers and half a dozen NGCs. All were visible more or less in the centre of the 26mm IR eyepiece ! (Apart from the ones which are invisible from my location....M1 M51, one or two others that are swamped by my local light pollution) I know i can fine tune things : My alignment stars were picked in a hurry and were perhaps not ideal and too close together. Its quite a novelty though typing in an object then moving the scope along the two axis following the pointer arrows and watching the coordinates reach zero, then look into the eyepiece and find the object sitting right there. I like it. I will spend the next few weeks fine tuning the Dob, and get to grips with all the settings and other features. Next thing is to fit my iPad in to place and wirelessly connect it to the Nexus and use the Sky Safari Planetarium app to its full potential. Thankyou agian for reading. My next mod will be a bit of tube flocking the purchase and fit of a new Spider / and secondary holder. Stay tuned !
