  1. From the album: My astronomy pictures

    Taken with my Canon 60da. Quite a challenge to bring them out. The most dim objects I have photographed so far.

    Rework of an old image taken with my trusty old Canon. Just trying to get the colour balance better

    Fresh lunar image taken with my QHY5-ii-mono camera. First attempt at lucky image video photography.

    First try at DSLR crop video imaging. 6000frames per image. 29 panes photo merged to make finished image. Seeing was pretty poor, but it turned out o.k. Will try again hopefully when conditions are better to improve on this effort.

  6. The original comments were about the HEQ5. I should think using my little pulley and weight mod would work really well on an HEQ5. Balance it as close as you can first, and then slip the weight on. No need to worry about what side of the mount you are on, or. meridian flips. You can add or remove washers to give the amount of bias you want.
  7. It does have magnetic tension, but my guiding is more consistent when the weight is in place. All gearing assemblies will still have play, not just in the meshing of the gears. The fact that the worm/motor unit moves in and out to engage/disengage will inherently have tolerance to move. If you can keep a controllable consistent pressure on the driven side of the gears it will run smoother and have less flex in the gearing unit as a whole. I don’t get so much variation in guiding when I have to flip to the other side of the mount. I suppose the bottom line is l like modifying things to make then run to their optimum.
  8. Hi. l use an alternative to balancing east heavy. Every time you have to do a meridian flip, you have to readjust your counterbalance weight, which can be a pain to get exact. What I do is balance as neutral as possible and then add a weight on a pulley. See image below. The advantage, is that the pressure is always the same even when you flip to the other side of the mount. The gears will always be in constant mesh. Just another way of doing it.

    Just reworked M42. Just trying a few different approaches to photoshop editing. Very happy with the increased depth and colour balance compared to earlier attempts.
  10. Thanks for all the input guys. It looks like longer subs of 5 to 6 minutes is the way to go. Using more darks I thinks is obviously going to help in cleaning things up, but longer subs to grab more photons seems to be the main route to solve the problem. Learnt a new trick though. Don’t always use Exposure and Gamma when converting from 32bit to 16bit. Try them all, and see which one gives the best results. Maybe everybody does that anyway, but l can’t remember seeing any video using anything other than Exposure and Gamma. Out of interest, do we really need to convert to 16bit. ?
  11. Working on the darks library as we speak, (or write). Cheers
  12. Hi used 5 darks. No bias or flats. l have just hit upon an interesting phenomenon. I normally convert in photoshop the DSS auto save down to 16bit using Exposure & Gamma. Thought I would try another option, Equalize & Histogram. Amazing. It just appeared. Do you think I could still do with longer exposures though. Check out the two results below using the two 16bit conversions. cheers ABF99BE7-7894-48B3-843E-C133D99E374E.tiff DBD8DC4A-7CA0-4B46-8372-74AE287AE424.tiff
  13. Hi Everyone Tried a new target last night, Bode’s Galaxy. The results were terrible. I think I have under exposed drastically. Could barely make out any detail in the galaxy. I did 42subs at 180secs. with a 102mm F8 refractor, and an Atik 490EX and CLS CCD filter. Any advice would be appreciated. Should I do more subs, or longer subs. Maybe 360secs. I thought Bode’s was quite bright. Had excellent results running 180sec subs on M42. The centre gets blown out, but the gas clouds are super clear. any thoughts. Cheers. Paul

    First attempt at monochrome photography. Stage 1. This is the luminance layer. 3 more layers to do. Red, Green and Blue. Need a couple more clear nights to get enough subs to build a colour picture. Takes a lot of planning doing it in monochrome. Thank the lord for U tube videos.
  15. Cheers. Trying to get to grips with all the options. Can you still see my location, or have I turned it of OK
  16. From the album: Equipment

    Pegasus focus cube. The most compact focusing unit ever. Light as a feather, and works beautifully.

  19. Added extra power socket to run dew heaters. Now everything is connected to the dec saddle. Good bye wiring spaghetti.
