  1. Thanks for your help. Doubt I'll find any camera used, where I am they rarely pop up on the used market Just going to have to spend some real time thinking whether £153 is worth it
  2. That's good to know, and thank you. So do you think getting a dedicated cam like an ASI120MC would benefit much? Because I saw on CN a small bore challenge and people with similar setups got absolutely incredible results. Although they probably have a lot more practice.
  3. Hi, I'm getting started with some basic planetary imaging with a webcam, and was after any tips if any of you could help me? I've attached some files of sum images I've taken. My question is, is there anything obvious I'm doing wrong? Also, what would you upgrade first? As I'm leaning toward the camera, seeing as it only does 30fps at 480p. It's just an xBox live vision webcam. Complete equipment list: 130/900 Skywatcher newt (spherical) EQ2 mount 90/900 skywatcher achromat AZ3 mount Celestron eyepiece/filter kit (not a good buy) - celestron 2x barlow svbony 5x barlow phone holder (phone is a samsung S8) Xbox live vision camera Thanks all!
  4. Hi SGL, is there any plugin or setting that can (more) accurately depict views through an eyepiece? I'm aware of the oculars, but what I'm after is the shimmer of the planets, dimming of DSOs when using smaller scopes, planetary detail dependent on telescope size etc. Thanks
  5. I'm pretty sure it's good, it's about 6 months old, I'm at a loss as to why it caused this, I've used it around pretty sensitive electronics where it really has to be high purity. Maybe the manufacturer just used a coating which happens to react with isopropyl. Oh well, all's well that ends well.
  6. Yeah, lesson learned. I make £5 an hour so you can imagine how worried I was to lose a £180 scope! Haha. Anyway, thank you to everyone that helped. Really appreciate it.
  7. Update: So in the end, I threw caution to the wind. I figured there's a chance this mirror is useless now, and I found I can buy a new one for ~£30. So, I rinsed it under deionised water, and cleaned away marks with a dishcloth. It looks okay, everything looks sharp and I popped it back in the tube and checked it out with some terrestrial viewing, everything looked up to standard. Looks like it could be a clear night here tonight-we shall see (or maybe I won't)
  8. They're not so much tarnishes as just parts where it hasn't turned green. It's strange, some guides say that isopropyl is okay.
  9. Also I tried running it under the tap again but it didn't come off
  10. I tried a bit of paper towel, just barely touching the paper against the mirror, like holding one end and letting the weight of the corner drag across this residue and it seemed to come away. Got some water coming today so. Question, is deionised water the same as distilled? If not, will it still work?
  11. Hi, I followed cleaning guides for my mirror (tap water followed by distilled), however I don't have distilled water so I used 99.9% isopropyl. It left this yellow-green tinge. Am I screwed? Please help 😧
  12. Also if I were to do the same with planets would the same happen, because the planets don't fill the frame
  13. Thanks for the reply, on this run it happened to be on planet but I've tried surface and got similar results (posted). I still get a kind of choppiness around the edges, and it's also blurry. Could this be down to using a webcam or is the scope out of focus or something? thanks
  14. Hi not sure if this is the correct place to post this, but when stacking in AutoStakkert!2 or Registax 6 my photos come out all blurry and choppy. I am manually tracking, perhaps not well enough, but I thought alignment and stacking were supposed to reduce this. I have also tried PIPP but to no avail. I'll post images how how they come out, along with settings. Thanks!
  15. Thanks all for the replies, this is such a nice community 🤣 think I'm gonna try again tonight if there's a break in the clouds, with my eyepieces I can only get 36x, 72x, 90x, and 180x so I'll probably just start with the lowest, probably like I shoulda last night, and build up to where there's a balance between mag and detail. Can't wait haha, gonna be a long work day
  16. Hi, complete beginner here first night out with my new Skywatcher Evostar 90, and managed to focus on Jupiter n saw 4 moons, which was awesome. But Jupiter itself was only a white ball, and could see some bands, but they were very fuzzy, as if they were out of focus, but I had it as focused as I could. It's been very hot today, could that affect the seeing? The stars don't twinkle too much, but that's pretty much all I can think of, as I believe a 90mm refractor should have enough aperture to resolve detail. Magnification was 180x.
