  1. Ok I'll throw in too, f/6 8" Dobsonian 8/12/2018 2:32am LGL62V smartphone... I used "Open Camera" in burst mode and selected the best image for processing in Snapseed. Had the image handy on my ☎ so thought to share some more / haven't clicked an image this year yet with my ☎ but have been observing Jupiter with my eaa rig weather permitting and it isent permitting much...
  2. So you know just what you have captured I added this graphic, to post your image in a wider field post process would require merging in onto a black background via Snapseed or other capable software or application. Pre process a wider field eyepiece or less magnification would suffice...

    Hi from London

    Welcome to SGL Mark, Best of Luck with the build and Clear Skies of course... Freddie.
  4. We just better hope a cme does not render them all useless because then replacement satellites would be launched before the old destroyed satellites orbits decayed putting twice the current satellites in orbit whatever that number is now and this would include military satellites some of which are uncounted. So I guess my point here is there is no real predictor as to what future numbers will be We can though count on an increase and if things go bad double that. If they go bad repeatedly and there are successive cme's than it might be worth finding another hobby or a hand crank generator...
  5. Yes iso and exposure look a little hot, try exposure bracketing your next lunar shoot. Use around 200 iso and 1/50 for shutter, the bracketing is just taking several shots around a baseline using different settings. The moon is a hot target and overexposure always a concern, bracketing insures better odds that a good exposure will be made... Freddie.
  6. I took the liberty of desaturating and fine tuning your image using "Snapseed" for Android, not bad at all for a single frame smartphone capture and you seem to have the drift method down quite well. I think they like us to post smartphone images in that section so this post might be moved by an administrator but none the less you did well like I said... My advice to move forward with babystepping smartphone imaging would be to add a cheap infra red blocking filter to your imaging train if you aren't using one already. I found for planets and moon this tightens up the sharpness of smartphone images of those objects considerably. It also works for solar smartphone imaging just be sure to have the proper solar filter in place in addition to the infra red filter and be sure to research solar observing before attemping it, there are some very good threads here on SGL describing well the do's and don'ts of solar observation. Best of Luck and Clear Skies Everyone! Freddie...
  7. I feel like I'm one of the few people in the world commenting on observing with Wombats at this moment, thanks for that Geoff... Freddie.
  8. This is really nice, thanks for sharing...
  9. These are very good indeed Avani, but two gas giants with highly active atmospheric turbulences would be awesome although somehow I think you would find a way to manage it all...And with flair I might add.
  10. Nice indeed, extra points for handheld shots you know ;-)
  11. Nice fiddling, music to my lunar ears it is...Thanks for sharing your tunes with us 😉
  12. A 200mm dobsonian is an awesome scope, get your friend to download Stellarum or similar planetarium software and read the book "Turn Left at Orion" some earlier versions of the book can be downloaded online free and are indeed still very useful. Best of Luck and Clear Skies of course both of you :-) Freddie...
  13. Welcome Simon, Best of Luck with your new telescope and Clear Skies of course... Freddie.
  14. Very nice indeed, looks worth the wait by a good margin. Weather has had me in a hard place too as of late...
  15. Excellent, lots to see there. The newly aquired newt is rocking it.
  16. Getting only about 1 to 3 nights a month here this spring due to clouds but if its clear I 'll likely see it as I'm an early bird or more of an all night owl, have yet to see transits via my new cameras and the laptop or planets for that matter and suspect it will be a bit of fun...
  17. Welcome to SGL, Best of Luck and Clear Skies of course :-) Freddie.
  18. Terrestrial/Celestial Suns, Solar images shot with just a camera, no external filters but stacking, time lapse, animations and other alterations are allowed like compositions, inverts and the like. Extra points for capturing atmospheric solar phenomena and since earth is actually an astronomical object and a celestial body, this type of challenge would/should be right up the stargazers alley. Some of you would call these images sunsets or terrestrial, but the sun does not set does it? Ones location on earth simply rotates away from it, the separation of celestial and terrestrial, a thin invisible line drawn precariously through our intellects 😉
  19. Most of the astronomy cameras in the 300 to 400 dollar range are small chip 1/3 sensor, of the two cameras I'm using in that price range I like the asi385mc it has a slightly larger sensor at 1/2 and an amp glow reduction circut wich works well the 1/2 sensor provides a bit more field of view. You can plug in all your scope and camera info here; https://astronomy.tools/calculators/field_of_view/ This will allow you to view some target's online with your chosen camera scope combo and get the jist of matching scopes to cameras, don't forget to add in a .5 focal reducer when calculating as the reducer is commonly used to speed up the f ratio and double the field of view.... Just select the imaging tab, the target, the scopes focal length and aperture, the cameras resolution this is the number of pixels width by pixels height, the pixel size - for the asi224 the pixels are 3.75 by 3.75 microns the same size as the asi385's are so the asi385 is the same camera with a larger chip (though more diagonal) and better amp glow control, then select focal reducer or barlow and your good to go. You can also download additional target's through the search feature and this I use often. Hope this helps. Freddie.
  20. I would only add that if there is a place at your observing site where you and your dob can be in the shadows this will help, if none is available a black shall or fabric hood can be placed over ones head and the eyepiece. Some even create a darker area with building materials or items that may be close at hand, an eyepatch can also be used and lifted when observing. Best of Luck and Clear Skies of course... Freddie.
  21. I'm just beggining in eeva but I have already noticed the equipment needed can vary considerably depending on what size the intended targets are you interested in...Large dso or small galaxies or maybe even wide fields, how much light pollution do you have? You may need a light pollution filter and if its really bad you might want to design your rig to be portable so you and it can travel to darker skies. Louise is correct that astronomical darkness is waning as locations in the northern hemisphere spin south and here in the US we northerners are just pulling out of the rainy season so slow it is and has been, but if you add some additional facts like LP info what targets your after some one is likely to chime in further. Best of Luck and Clear Skies of course Stew... Freddie.
