  1. I also have the AZ GTI and use it currently in ALT-AZ mode but I use a StarTravel 102 and can manage 30sec images. I did have a few issues though and only recently sorted them. What I found was make sure you have good power, the power adapter I was using wasn't good enough. Make sure its level and the clutches are nice and tight, that made the biggest difference for me. I also do 3 star alignment, starting by being level and pointing towards Polaris. Since doing this I have been fine, I think you should be able to manage 30 seconds. 

  2. Hi everyone, I have recently started to attempt some Astrophotography. My first attempt seemed to go pretty well capturing the Orion Nebula using my budget setup (Sky Watcher - Star Travel 102 on a AZ GTI Mount for basic GoTo guiding and a Canon 1100d un modified). I took about 300 x 4sec at 1600 about 30 darks and flats. , I know the centre is over exposed but I was pretty pleased with my first photo.

    But ... since then I have really struggled , after I took that pic I bought a light pollution filter from FLO as I'm in a Class 6 Bortle area and I attempted the Rosetta nebula but couldn't see anything , then tried the Horsehead nebula but only got a red band across the photo. Thought it may be the filter so removed and tried again but it was exactly the same. I know longer exposures would help but I only have a budget setup at the moment. I do plan to modify the AZ GTI so that it can do EQ and maybe adding guiding cam in the future.

    So my big question is what would you recommend I look at upgrading or purchasing first to help capture more targets and can you recommend some other nebula / galaxies that I could see with my current setup? I think I was too ambitious attempting the Horsehead nebula.

    Thank you for any help
