    I was looking through mine today and discovered that they have gone out of collimation. Objects in the left lens appear to be higher than in the right so when you are looking through both it's like you've had a few too many drinks! Before I bin them, can anyone suggest anything that I can do as I can't see any adjustment screw or anything. Peter

    Hi Everybody

    Hello and welcome. Peter

    That certainly looks like Sodium to me. You can usually tell just by looking with the naked eye - does it have an orange glow. If LED lights are coming soon then I would not bother with a CLS. Peter

    A CLS filter will help to reduce light pollution from Sodium (Orange) lighting. It won't really help much if you have the more modern LED (White) lights. For those an IDAS D2 filter will help. Peter

    I quite liked the second episode but I wish that the background music wasn't so overwhelming. Also he seems to tells us what he is going to say then he says it and then he tells us what he said. Bit repetitive I thought. Peter

    It was taken with my C9.25 with a 2.5 Televue powermate and a Canon 550d. I took a video exposed for Jupiter and one exposed for the moons and combined them. If you expose for the planet only you will not see the moons. If you expose for the moons the planet will be blown out. Peter

    Where a DSLR really comes in useful is when you want more widefield shots to show the moons: Peter

    2. A DSLR is not really suitable for planetary imaging - you want a high frame rate camera like an ASI224 or similar. If you use a DSLR you will find that the planet(s) are quite small even with a Barlow etc. Peter

    1. Camera will either be imaging or guiding - not both. 2. Ideally for guiding a mono camera would be best but you might want to get a colour camera so that you could also use it for planetary imaging without guiding. 3. The issue of finding a guide star will be the main issue. 4. Some people use tablets but I would always use a laptop myself for the power. Peter

    So......a fairly normal met forecast accuracy then! Peter

    I watched it. Too much time taken up with Earth I thought. Peter

    The standard answer is to read Making Every Photon Count first but, in answer to your question about colour - yes photography will bring out colours that you cannot see because of the length of exposure used. Don't just jump into astrophotography because you can make expensive mistakes that way. Peter

    I have used my AVX for imaging since 2014 and find it gives good results with my Ed80 or Ed120. There is the "stiction" issue but it's never been a problem for me. It is also very capable with my C9.25 for planetary imaging. If you are going to use ASPA just make sure you follow all the steps required. Peter

    You could also check out West Yorkshire Cameras - they have all sorts on their site. Peter
  24. PeterCPC
    That depends on what you want to do. The 40mm STM Canon will give you nice widefield views. If you are looking for really cheap lenses then you might have to consider an M42 lens. The trouble is that you get what you pay for. Peter
