  2. T7 Astronomical Camera

    On 19th Feb (Full Super Moon) I set up the 10" SW dob on the EQ6Pro and plugged in the S7 camera. Using Stellarium for guiding the scope and Asicap for the camera. Skies were clear with no cloud, but there was a lot of atmospheric heat aberration. Very common here during the summer months causing rippling of image. Previously I had driven the cam on test around the kitchen using the stand alone lens. On this occasion I used it in prime focus with the 70% aperture ring. As the image shows it has ginormous magnification. Focusing was somewhat difficult as it appears the Dell 1500 laptop was having memory issues and lagging, so focusing was a hit/miss issue. The S7 is quite complex in setting up using the ZOU software, and on the first run I failed to limit the number of frames and it banged off 5G worth of images and files!! Each image is also accompanied by a text file give the parameters of the shot. Eventually I got things setup and reasonably stable and set the frame batch rate at 10 frames per run 16bit RAW. The 2 images below are #1 single unprocessed image as taken by the camera. #2 is 10 images, stacked in Registax and touched up in Photo Shop Not the best of my attempts, but does show the potential of the device. I have a spare Dell 790 (SFF) which has a better video card and RAM I will later check it out and dig deeper into the intricacies of the beast. At least I scored a break in the cloud cover that rolls in regularly every night...... Last night (20th) very cloudy by 3am blocking the moon and everything else. I have since cleaned the mirrors of the 10", they were not the best having been in storage for over a year. Dave

  4. A night under the arches

    No defocusing, that is animated star trails effect using starstax and Premier Pro. I only use my Sony cameras now. I sold all my telescope kit as I had nowhere to set it up to use it Best wishes Gordon
  5. A night under the arches

    Stunning stunning work my friend. Are you defocusing it at 27 seconds? And again at 120 seconds? Looks epic Gordon. And where is the C14 these days? Ray

    Yes it was -5C when I took that image - but it seems to be warming up again now - back into double figures Greg

    Probby PS light room ! Dave

    Geesuz Dave, that's actually quite good. I'd like to know what processing they did. Ray
  9. Greetings

    Thanks mate. I was on a boat (not my boat unfortunately) and then in Sydney for the last week. Ray

    Wow, Noel pulled some good stuff out of your data mate. Beautiful shot. I believe you have some seriously cold skies there at the moment. Ray
  11. Flaming Star

    And here's the Noel Carboni process of same. Greg
  12. Flaming Star

    7 hours of 30-minute subs on the Flaming Star nebula region in Auriga. Need at least another 7 hours on this one. Greg
  13. "A night under the arches" I went back to Ribblehead Viaduct last night to shoot some time lapse, animated star trails and some slightly different views of the viaduct, I didn't attempt any Holy Grail time lapse as I only had time to be there for the hours of darkness. It was clouded over and very windy when I got there but an hour later the skies started to clear and it stayed that way for the night. Apart from the noise the odd train, the wind and the continual dripping noise from a drainpipe on one of the arches it was very peaceful, it's one of my favourite places to go at the moment. I took my Sony A7iii and A7Sii with a Samyang 12mm f2.8 fisheye and 24mm f1.4 lenses. In all I took about 2,000 images from which I made 4 time lapse clips and 4 animated star trails as well as the single frame and 5 frame panorama images below. The exposure times were 30 seconds at f2.8 and ISO 6400 for the A7Sii and 12mm lens and 20 seconds at f1.4 and ISO 4000 for the A7iii and 24mm f1.4 lens. The moon rose at about 2am and created some wonderful lighting effects in two of the clips making it look almost like daylight with the long exposures. All the puddles started freezing over in the early hours but thanks to my down suit I was nice and warm, the biggest problem I had was stopping my ground sheet and bed roll from blowing away, after the third retrieval I weighted it down with my hiking trailer and spare tripod. The images were processed in Adobe Lightroom and rendered to video in Premier Pro while the animated star trails were created using Starstax and Premier Pro. The time lapse video can be seen at the link below in HD and 4K. I used a wireless intervalometer to take the "selfies" https://www.youtube.com/watch?v=_3qFFRhLcIY&t=5s Best wishes Gordon

    Good news on the cancer front my friend. Stay well. Congrats on the cam purchase. Shane

    BTW. British Airways are Celebrating 100 years of service by painting one of their aircraft with the old B O A C logo.

    Here ya go I will look for the internal picki later Magnificent machinery Argonaut 1957
  19. Comet Wirtanen 46P

    I am sure I have a picture taken inside the Argonaut showing the right wing and propeller on a trip back to the UK from Cyprus after my time there during the EOKA campaign. I was stationed at Combined HQ in Nicosia. Dave

    Crazy. Got any pictures of those or the rigs back then? Would have been vastly different times and technology. Ray
  21. I knew someone was responsible, at least you are honest about it. That crazy that you can purchase that camera like that and its giving you similar readouts as the ZWO. I wonder how the images will look? I would consider purchasing one of those if it fits the bill. Keep me posted of your results please. Good news my friend. You are a tough bugger. Onwards and upwards. Ray
  22. T7 Astronomical Camera

    This is an image by manufacturer of what the camera is capable of. Does not give any further detail but does look quite good. When our Clouds with meatballs and gravy disappear I will try it out. Dave
  23. T7 Astronomical Camera

    I have found a set of images of the Cloned T7 Astrocam (ZWO ASI120c) I purchased. I will save a few thousand words with the images which are self explanatory. As you can see its very versatile and can be used as a stand alone cam, as a prime focus cam or a guiding camera. It also has a guiding feature with supported mounts. Prices vary on EBay but around $100 - $128 AUD. Software and drivers available from ZWO web. You need to download all to work. The "Asicap" software contain a full rundown on setup and use in a Help PDF file. Dave
  24. I RSVP'd to this from my MediaTek Tablet but looks like it never made it! Yeah, real crazy Ray. Meatballs with gravy! But I must apologise for it because I believe I am the cause! I just received a neat T7 Scope camera. Its Chinese clone of the Chinese "ZWO ASI" range on cameras which are very expensive. It came with no instructions/software and looking at Forums found that it works using the ZWO drivers/software. The unit cost me $AU109. USB/Network compliant. Got it from Ali Baba site. in fact it identifies as the ZWO ASI120C architecture which is a simpler unit. Mine has the wide angle lens and different sized apertures. I have tried it out on the Dell in the kitchen and with the Wide angle lens can take pictures straight from the cam alone down to a metre or so. Will have to wait for this weather to clear B4 aiming upwards. We have had a fair amount of moisture the past 48 hours - enough to revitalise the sick looking shrubs in the garden. Its an ill wind ....etc BTW Saw the Oncologist last week and given the all clear on the Cancer situation. 100% under control and the spine is now regenerating the damage done by the now neutralised cancer cells. Will now monitor me every 4 months. Same with the Kidney, no issues, no cancer and monitor every 9 months. That's a load off my mind. Dave

    Ha ha try working on an Oil Rig (Big John) in the Timor Sea with those sort of temperatures accompanied by 90 to 100% humidity for 2 weeks at a time. Water literally ran down the bulkheads (walls) of the rig It was hell for those on the drill floor and not much better in the so called airconditioned offices and messrooms etc. I also spent 2 years in Bahrein back in '54 It can get well up in the high 40's in summer especially daunting for newcomers when coming in on a plane, when they open the doors the heat rushes in like when you open an oven. That's when BOAC Argonaut's and DC3's regularly flew the skies. Had those long whirly things on the wings! At least the money was good on the oil rigs Dave
  26. Comet Wirtanen 46P

    I've felt 50 degrees in Crete and Arizona - it feels life threatening walking down the street. Greg
  27. Holy moly! Most people only know what a prime number is from watching Contact. Ray
