  1. I was looking at the Hyperstar/Faststar mod for my 9.25 SCT. I nearly fell out of my tree when I saw the price at around £1100!!!! That is more than the cost of the OTA by a long way. Just wondering: 1. Is it worth it 2. How Celestron justify the eye water and nether region cringing price?
  2. If it was purchased new and the lens damaged on arrival then contact the supplier to replace the lens.
  3. I try and judge resolution by the smallest crater/rill/ridge that I can see clearly in the image. I use a variety of sources for feature sizes, the Cambridge Photographic Lunar Atlas is particularly good. Sorry about the late reply things were getting out of hand at work.
  4. Will give that a go.... My most recent image, what I would call real 1st light as ,y images above were grabbed through fleeting clouds...now improved thanks to posters above with their suggestions. The Sharpcap manual superb. Gave me a lot of help.
  5. Nice report and an interesting read that one orf our own members observed it.
  6. Thanks for the suggestions Michael...now re processed the image with the square 'embossed' on it.
  7. Yes Electronically Aided Astronomy Electronically Aided Astronomy. Of course now I have bought this beasty the nights are getting lighter.......so getting to use in EAA mode it along with getting up for work is going to be a challenge. I am impressed with the solidity of the camera overall. The fan is almost noiseless. It came well packaged too. It was supplied with a USB3 A to B type cable but that was 1.8m cable but that was a bit short in the obsy, so I ordered a 2.7m one off Amazon. I have not fully tried Altair's own software which can be downloaded from their website. It works very well with Sharpcap and I don't get any drop outs which I did experience with the ZWO's. Thanks for the Stacking tip Michael, useful to know and I was puzzling about it. Thanks to others on our wonderful website I have also solved the documentation and user manual issues I had. ZWO do a near clone using the same imaging chip but it is not fan cooled and is about £50 cheaper.
  8. My 1st images grabbed on 16th April around 1 a.m. BST on my 9.25 SCT at native focal length (2350mm) I sold on my two ZWO120 an MC and MM to help finance the AA178. They were good cameras but I wanted something cooled and with a little more resolution and the ability to do EAA. A learning curve as the controls in Sharpcap come up differently and there are more of them for the actual camera. The larger image was at 1x1 (no binning) and the smaller at 2x2 binning, I also learnt to make better use of the ROI (region of interest) making it smaller and upping the frame rate. I tried at the imaging full chip setting and with the 6.2mega pixel capability the camera slowed down on frame rate...probably due to my computer not being able to keep up despite using the USB3 connection on it. Another new control was the choice of formats, RAW8, RAW14 RGB. I chose RAW8. Overall I am quite please. These were 2000 frame runs, stacked in Autostakkert and the sharpened in Registax using wavelets. It was nice to capture all for Galilean Moons too. Much more to learn though....
  9. Thanks for all the answers, will follow up.
  10. I have just bought one of the AA IMX178 cameras and the documentation supplied compared to ZWO is woefully inadequate. I have been using ZWO 120's for a year. Not even anything on the AA website in the way of documentation etc. I used this with Sharpcap this morning at 2:00 and it worked well enough and the initial images are OK, but when I used AA's own AtairCapture software it saved the video files as .SER extension. What is a .SER and can it be converted to .avi? Plus there are a lot of control on that software and no info offered on what does what. Is anyone else using this camera and can they help? Is there a general guide as well to EAA as this is one of the reasons I bought this camera.
  11. When I take images of the Moon and have processed them I try and measure what the smallest feature I can see in the image. I usually get 2-3 Km rills and craters quite easily. This will be a function of the aperture of the 9.25 SCT but more importantly the seeing conditions. I use the SCT bare at native focal length and if the seeing is good I am now pushing it with the 2.5x Powermate. As a reference to crate sizes I use the Cambridge Photographic Lunar Atlas. Our colleague on here ,Astrovani, achieves some incredible resolution, but I think he is use a 14'' SCT
  12. The Moon at 6.4 days on Sunday 2nd April. A single shot with the Canon 650D then stacked images from the ZWO120MM, with the more detailed shots using a 2.5x Powermate. Atlas Hercules 20_46_13 as rs ps.tif
  13. The 4 day old Moon on Friday 31st March. One single shot with the Canon 650D on my 9.25 SCT, then some detailed shots of 1000 frames using the ZWO120MM video camera. I even managed to push the scope by adding a 2.5x Powermate for some close ups.. Stacked in Autostakkert, tweeked wavelets in Registax and finished in PS Mare Crisium 19_30_32 RS.tif
  14. Nice scenery and a lovely country where I once lived....but of relevance to UK star gazers NONE! SAN has continued to drift away from what it was and should be. It no longer caters for the amateur astronomer. Just a platform for rather average presenters.
