  1. Thanks for the suggestions, a few to look at there, and I appreciate it will never be accurate. I think rather than knowing when will be good, I’m more interested in if there is a slight chance. If there is heavy cloud and rain I know it is probably worth not bothering.
  2. Does anyone have any recommendations for a free astro weather API? I've been building a display screen at home for a few various sensors and have a bit of space at the bottom. Giving a rough indication of how clear the sky will be for either that night or the next 4 nights would be great. I found once reference to DarkSky, but it looks like earlier this year they were bought out by Apple and dropped all useful features. I have found a few, but not many of them give things like seeing that you get with some of the apps like AstroPanel.
  3. You posted the same one twice there. The one I used is: https://www.thingiverse.com/thing:241592 I picked up a Celestron Red Dot finder for about £15 and printed one of those, then I'm not always taking it on and off my scope. It has been really useful and cheap to produce. There are some 3d printing services online if you don't have a printer. I'm sure they would knock one of them up for a very small amount.
  4. I had a go at imaging Mars on Sunday night. No cloud but high humidity (I could see a triangle of light coming down from a nearby street light, which is my usual judge of conditions). Any advice on the following image? I decided to do a mosaic of a raw frame->stacked->sharpened then reduced to normal size again. Did I sharpen it too much? The image increases in size, as I used "Drizzle 3.0x". Kit & process: Celestron Nexstar 90 SLT (90mm scope), ZWO ASI120MC, SharpCap. Processed in AutoStakkert, taking the best 40%. Sharpened in RegiStax. I did struggle with the focus.
  5. Cheers. I have been subscribed to sky at night for a few years and never noticed that service. I have probably ignored it as a spam generator. I’ll give that a go.
  6. Rather than the long dovetail bar, I have started using the small green dovetail, which my camera ballhead can connect directly to. I polar align, slot in the ball head and adapter and swing my camera around. It was taking me a while to get my targets framed up, so I bought a celestron style red dot finder for about £12 and got an adapter so it could fit on the camera hotshoe. I have to make sure I don’t knock the tripod and make sure everything is nice and lose before I turn it.
  7. Cheers for the further advice. There are a good couple of lens options there from MPB. I get another pay day in a week, I probably need to set a bit more aside but it looks like I can get something reasonable for only a bit more than I planned.
  8. My budget at the moment is probably £100 max. I can wait for a better lens but £900 is a long way off my spending for a lens at the moment.
  9. Cheers. Macro is not that important. I was mainly wondering why many of the lenses I was looking at were described as macro and does that make them unsuitable for astro.
  10. Thanks, that does look like a pretty good lens. A bit out of my price range at the moment but I’ll keep an eye out for bargains. That is f/4.0 at its widest and I was wondering if a lower f number would be better, or does that matter less when you are on a tracked mount?
  11. Wow, cheers. The 14mm looks like the better choice for what I want.
  12. I'm looking for a new lens to add to my kit, currently using a Canon 18mm f/4.0-55mm f/5.6. I want to be able to do wide field images of a Star Adventurer Pro mount. Funds are tight so I'm looking at second hand/ebay market. A 24mm f/2.8 seems fairly common, though many are described as a macro wide angle lens. Just to check, does this mean it is good for both macro and wide angle landscapes? A lens that can do great close up pictures of bugs around the garden would be great, but I want to make sure it is suitable for the prime purpose and get some lovely Milky Way shots. With a Canon EOS
  13. Anyone got some recommendations for the best place to keep up with the latest astronomy news, especially what is visible from the UK? I missed the news about the new comet until mainstream media started posting impressive pictures. Typically it is set to be cloudy here for the rest of the week! I've checked a few news sites and there is no mention of it in a lot of the news sides. I need somewhere to add to my daily trawl of news that is far more interesting than Brexit and Coronavirus!
  14. Cheers, that does help. I have a reasonable knowledge of the sky, recognizing most constellations and occasionally just use binoculars for that quick look about before going to bed, so I should be able to get by with this. I'll probably keep a tablet with stellarium to hand too.
  15. Hmm, yes M66. Why I should double check what I'm saying in posts before clicking 'reply'!
