  1. I dont think you can really compare a bright artificial light moving across the sky to Jupiter (which, compared to a satellite is pretty much seemingly stationary) . I'm also quite sure that the majority of visual astronomers wont be very impressed by a bright light flying across their fov when trying to observe some faint object. These may not be a massive issue right now but in 50 years or so they will become more than just 'a drop in the ocean'.
  2. I fear there will come a time in the not so distant future that we amateur astrophotographers will only be able to benefit from solar AP if monstrosities such as this proposed eyesore are anything to go by. https://www.newscientist.com/article/2337336-huge-satellite-could-outshine-all-stars-and-planets-in-the-night-sky/
  3. @Steve Ward Although a bit too wide for me that looks a very nice lens for those milky way shooters.The manual focus lock switch also sounds good, it would be nice if this started to become incorporated into Len's with a narrower FOV aswell
  4. If your after a fairly wide FOV & wanting to move away from a reflector, another option would be a lens. In particular I'd highly recommend the Canon version of the Samyang 135mm f2 ED UMC manual lens. There's a VERY long thread (quite rightly) singing it's praises here Cost wise its way less than a decent triplet, very friendly weight wise for the mount & it's capable of producing excellent images. I took this with mine.
  5. Very nice indeed. Zooming in on this, the star field is processed perfectly. I definitely don't think denoise would have added anything to it, more likely it would have done the exact opposite.
  6. As mentioned by a few so far, an 8" Dobsonian is a great place to start, it's not too big to be carried to the garden or to the car (for visits to dark sites), it's very easy to set up & use and will give you good enough views to keep your interest. Also as mentioned above, don't worry about collimation, it's not that hard to do & once you've got the hang of it it becomes second nature. The majority of reflectors don't need to be constantly collimated unless you start looking at very fast newts & (f3 & below but these are mainly used for imaging) the likes of a Skywatcher 200p Dobsonian @f5.9 is fast enough to gather plenty of light but not so much that collimation will be an issue (my old SW 200p f5 newt was with me for 2yrs & travelled in the car with me all over the place & I collimated it twice) Also don't worry about cool down times, a 200p newt will take around 20mins to cool to an average night time temp of approx 5c, it's only really Maksutov-Cassegrain & some of the bigger (10"+) newts that take a bit longer to cool down. steve
  7. @AstroMuniThanks for the kind mention Pramod. It was good to do business with you, a nice uncomplicated transaction. I'm glad your happy with the camera & I think you'll get a lot more use out of it than I've had due to work etc. Judging by your first couple of images (which btw are very nice) with it it looks like you've got the hang of it very quickly. I look forward to seeing your future images. Kind Regards Steve
  8. The EQ5 is a good solid mount. Years ago I had my Skywatcher 200p mounted on one so it'll handle your 150P-DS easily. If your only going to dabble in a bit of planetary photography its easy enough to move the scope by hand so the EQ5 will be adequate for a bit of that . DSO's on the other hand are completely different to image. For planetary you ideally need to film the subject (large numbers of short video clips & then run it through a program such as Sharpcap). For DSO's you ideally need a motor driven EQ mount to take long exposures (in fact i'd say its imperative to have one if you want to make a very involving hobby a little bit easier). What you really need to think about is how much photography you think you'll do. This is an impossible question to answer though in reality. The reason I ask though is that you dont want to buy the EQ5 & realise you really want to give AP a decent go & you then have to buy a good mount for AP such as your aforementioned HEQ5 (Which in my & many others opinions is a very good, capable mount for AP) Equally you might buy the HEQ5 try AP, decide its not really for you & then you've spent £££ on a mount thats really over the top when its only used for visual. So i'm afraid theres no real answer I can give, its really up to you & which way you want to go. What I would strongly advise is buying this book (Link below) which will give you a great deal of info for someone starting out in AP (it will also potentially save you money buy advising not just what to buy but also what NOT to buy). The worst thing you can do & I think pretty much everyone on SGL whose been down this path before (myself very much included) is to not do enough research first. Its very easy to make the wrong purchase when it comes to AP & believe me, AP can be a VERY expensive hobby meaning purchase mistakes can be equally as expensive. Good luck & heres the book https://www.firstlightoptics.com/books/making-every-photon-count-steve-richards.html Steve
  9. @woldsman Here is my Samyang setup. I'm also looking at ways to mount the EAF. I'm posting this to give you another idea of Samyang/Guidescope mounting options. Steve
  10. Brilliant, thats great to hear. It took a fair bit of trawling forums & a fair few moments of frustration but it was worth the grief in the end. Good luck with it & clear skies. Steve
  11. More parts arriving for my upcoming PI dedicated PC build. 32 GB of RAM came yesterday with another 32GB in the post, a total of 64GB RAM @3600MHz should certainly see an increase in performance compared to my old build with 16GB. We're still having unbelievably bad weather up here in the Lakes with the very rare clear nights since December either been too windy or the early 4am starts for work which I do alternately are typically falling the morning after any clear night 🙄 Its these inactive nights that get my brain thinking of projects to fill my time with whilst not imaging & this has resulted in the new PC build. I recently came across a YouTube video all about a small very niche hobby which I didn't know even existed, never mind actually been a 'thing' & thats custom build mechanical keyboards, these keyboards can cost well over 3k (Yes you read that correctly £3K 😱)...... i've been sucked in 😂 My first board arrived yesterday, its at the cheaper end of this market so I could see what the fuss is about & I have to say that typing on it is a surprisingly nice experience. I've ordered custom keycaps, buying them is a minefield as each brand has a certain weight, sound etc (Sad I know 🤣) so i'll be spending the weekend stripping the board down, sound proofing it & lubing the switches....Don't ask 🤣 Anyway, its keeping my brain busy. Steve
