    How do amateur astronomers make money?

    For 30 years I owned various sailing boats. Sailing has been likened to throwing blank cheques into the water. Was it worth it? Undoubtedly, it has given me memories that will live with me forever.

    Talk to a Photographic Society ???

    I was given tickets for an astrophotography lecture one Christmas. The talk was entirely about cameras, tripods and terrestrial photos. I felt so short changed that I wrote to them later saying I was disappointed not to have seen deep sky pictures. Having seen some of your images I would suggest it is essential that you show deep sky images. That is the area that amateur photographers will know least about and will be most interested in. All the best. Jack

    PHD2 Setting Up

    Thanks, I reduced the gain to 1 and managed to get an image to focus. Jack
  4. I have a Celestron CPC 925 telescope and I am using a Zwo ASI120MM camera to guide using PHD2. I have focused the telescope in daylight on a neighbours TV aerial using my Live View screen on my taking camera, and I am trying to get the Zwo also in focus. The image I am getting on the PHD2 screen bears no relationship to a TV aerial, it is more like a carpet design. I have tried altering the Gamma slider and trying all exposures from 0.001 sec up to 30 seconds, changing the Gamma slider and also the position of the camera. All that happens is that the image gets darker or lighter as the Gamma slider is moved. I have my taking camera, a Canon 600D set up at 100 ISO and exposure of 1/800th sec. This gives a properly exposed image on a bright sunny day. I have also tried changing the Zwo exposure on PHD2 to 0.0001 sec on the custom section of the exposure bar. According to the writer of the PHD2 Manual, this setting up should be done in daylight and this seems to be very sensible. I have read on another website that what I am trying to do is impossible and that this focusing adjustment must be done on a night sky. I have also read about people who claim to have done what I am trying to do in daylight. As usual, in my experience, I am running into difficulties on what should be a simple process. There are 2 possibilities: I am stupid, and there is an obvious answer which I cannot see. The writer of the manual is wrong, and this operation needs to be done in the dark. ( a feeling I am becoming used to) Can anyone clarify. Thanks Jack

    Lunar Imaging Books

    There is a good book called "Shoot the Moon" by Nicholas DuPont Bloch. It can be seen on Amazon at https://www.amazon.co.uk/Shoot-Moon-Complete-Guide-Imaging/dp/1107548446/ref=sr_1_2?s=books&ie=UTF8&qid=1525437756&sr=1-2&keywords=shoot+the+moon. Second hand copies are available for around £9. This book was reviewed by Sky at Night a few months ago. Hope this helps

    Thanks, It is accepting it now. I was trying to use PHD not PHD2. Thanks

    I have tried downloading the Ascom Platform and the Ascom driver and PHD does seem to accept that, why not the suggested method?
  8. I have just bought a new ZWO ASI120MM and I am trying to connect to PHD. I have downloaded the driver from the ZWO website and the camera shows in Device Manager. It is also recognised in SharpCap and I can see changes on screen when I remove the lens cap, but when I try to link it to PHD using the Windows WDM as suggested in the user manual, I get the following reports: Error Initialising WDM Services Problem connecting to camera. The PHD screen seems very simple and this seems to be the only way to connect the camera. I have tried almost all of the other options in the dropdown menu but nothing works. Any suggestions? Thanks

    New invention heralds huge scopes !

    It is April 1st. Any connection?
  10. Thanks for all your comments. I have now tried free trials of PI and APP. I think I will go with PI when the trial periods expire. It will not be the easiest option, but with a little patience, which is not my strong point I think I will be able to use it adequately. It seems to be also a programme which will last a long time, I will probably never use all of its functionality, but it is comforting to know it is there. Thanks again. Jack
  11. I should add that I regularly use Lightroom 5 for conventional photography and I also have an old copy of Photoshop Elements.
  12. Thanks for the replies. I am using a Celestron CPC925 either with or without a Celestron 0.63 focal reducer. My camera is a Canon 600D which has not yet been modified, but I intend to get this done over the summer months. Left brain or right? These days I'm not sure if I have a brain. In a more serious attempt to answer your question, I was a chemist ,not pharmacist many years ago. I have already downloaded a trial version of Pixinsight and am slowly making some progress, but it is quite difficult. Before going ahead to buy it at the end of the trial period, I am just checking to make sure this is the right decision.
  13. I intend to buy a software package soon but I am confused about the relative merits of each package. What would be your advice taking into account: Ease of learning. I am 77 and may not have too long to spend learning. Functionality. I am mainly interested in nebulae Cost Thanks
  14. Prof. Eric Fossum who is credited with inventing the CMOS chip is working on a new sensor which he claims can "count every photon". See the following: https://www.dpreview.com/interviews/9385721576/perfect-sensors-may-be-possible-but-might-not-come-to-cameras?ref_=pe_1822230_274249150_dpr_nl_301_13 How long before we get this for Astrophotography?
  15. Fox Talbot invented photography in 1840 and we have used the noun "Photograph" and the verb "To Photograph" ever since then. In the area of Astrophotography however we use " Image" and "To Image". An image can be created in many different ways, e.g. using a camera, painting a picture, flicking paint from a paintbrush onto paper, nude bodies covered in paint crawling over paper etc. Why then in this very Scientific topic of astrophotography do we use such imprecise terms to describe what we do? Is it fashion or am I just a dinosaur?
