    I just started using the DSO Browser and I am impressed. This is an original idea put to work on an outstanding platform. I find it very useful to plan observations and photo sessions. The hourly elevation and the monthly elevation graphs are awesome and helpful. I plan to use it on a regular basis.

    This continues to be the best resource of its type, now become essential for me for researching and choosing imaging targets. It means a lot less wasted time than there was. It's hard to think of any way in which this app can be improved, it does so much and so well.

    I love the site! It is my favorite “go-to” for session list generation and looking for DSO info.

    Very great job with your website, I'm using it constantly since I found it! It's really that good, thank you!
    Sergio, Israel
    I've been using this for a while now and it's an amazing and educational venture! I urge any and all finding this to join in. Two things I look for on the net: beautifully done and free-of-charge. The DSO Browser passes this test with (truly) flying-colors!

    Thanks for implementing the “Telescope Simulator”. Superb feature!
    Paul, England
    I think this site is a god send. I use it all the time for planning what I am going to image.
    James, England
    Thank you for creating this wonderful site, it is my favorite and I always use it. I've been to a lot of astronomical websites and so far this is the best one I've seen.
