  1. Hello Peter. A little more detail on what exactly you are hoping to achieve would be helpful in giving you helpful advice. However even without this I would suggest that a cheapo barlow is not the way to go. I owned and quickly disposed of a cheapo one once, the lens elements actually rattled in the housing. That's not going to help at all. I now have a decent meade short barlow and also a tele extender from explore scientific. Both are under a £100 and perform well depending on intended use.
  2. I would basically concur with all the advice above. Telrad or rigel finders used in conjunction with the provided finder scope works very well. BTW @JohnI like your finder setup, looks like you can operate the two effectively with minimal head / body movement. Regarding your eyepieces dewing up. Have you been putting the eyepieces into the rack on the dob base, if so don't bother. When not in use either put into your pocket to keep it warm, making sure there is nothing else in there (eg car keys) that could scratch the lens or buy a dedicated case to use for your eyepieces where they
  3. I had to recollimate my laser recently, it is a fiddly job and best done with a lathe
  4. As long as it is correctly collimated itself and isn't sloppy in the focuser draw tube then I would have thought it should be fine. Happy to be corrected. I can't find the one you mention available on amazon but FLO sell a basic but perfecftly suitable option. https://www.firstlightoptics.com/other-collimation-tools/astro-essentials-cheshire-collimating-eyepiece.html
  5. Yeah was nearly a complete waste of time tonight but I did actually get something out of it in the end. It started with me packing the new dob into car to access a darker sky for further evaluation of the capabilities of it. Prior to this I checked BBC weather, clear outside and Ventusky. All gave me a similar result of cloud early on clearing to give me a couple of good hours of good clear sky, hmm think the cloud machine got switched on somewhere because it was challenging all night. So what happened is I found myself fighting said cloud for the 2 hours I stuck out and all I act
  6. Don't forget to add ink black skies to the equation!
  7. yeah fiddly I agree peter but once it's bolted down you shouldn't have a lot of movement so recollimation will be infrequent you would hope!
  8. It was only quick session, off out to a darker place tomorrow to do a little more all being well. However inline with other reports on here Mars is looking lovely and contrasty, I think my magnification was circa x190 with the binoviewers plugged into 127 Mak. I didn't manage the polar icecap because although there was good contrast with the pink and bluey grey areas easily identifiable and well separated, the skies are not settled enough to pick out the smaller icecap yet at 9.15 pm and so it was a little mushy at the edges. Had a quick 10 minutes at the moon as well, the termi
  9. What he said basically. On the same note I would challenge anyone to notice any difference that would make a real difference to your viewing pleasure.
  10. Using a bigger aperture then an OIII works amazing on Orion however using a 120mm aperture I would say a UHC would serve you better. The astronomik from FLO have a nice tight tight bandpass across the relevant frequencies although the much less expensive Explore Scientific are not a million miles behind it if your on a budget. https://www.firstlightoptics.com/uhc-oiii-visual-filters.html
  11. I just went outside to have a gander at the moon with the intention of carrying out some testing of my binoviewers, conditions seemed fair and so yeah, let's go for it. I came inside, set up the mount/tripod and mak then went outside. Where did the wind suddenly come from, brrrrr that's me back inside fgs.
  12. I don't think the 150p would work, its the length as well you see. Slightest bit of wind and it will flap like a flag
  13. Imaging eh, that's my que to leave this conversation. I have "very" limited experience with this and will leave it there. Strange you say a 200P wouldn't fit in the car, it is only around 1.2 metre in length once removed from base but as you say, not fit for imaging so it matters not.
  14. The moon is under rated by many. One man's pain in the A... is another mans beauty. Planetary is not affected by the moon, doubles and clusters (to a certain limit) are not effected by the moon that much. Get yourself a pair of binoviewers and look at the moon and you may find something completely new and beautiful in terms of what you see.
  15. Another consideration for you. I get your aims regarding footprint but maybe you are not fully aware of the space involved with a 102 refractor plus mount and tripod or a simple 200 dob. I have not owned a 200 dob but have used one and am aware of the size of it. I do have a 102 frac plus mount/tripod and I don't think the difference in space used is that much different. Also a 200P dob is around 200 quid cheaper which would easily cover the cost of extras such as a decent zoom eyepiece, a telrad finder and maybe a barlow.
  16. As per the above you just set your phone so it does not auto sleep, also make sure your phone is connected to the mount wifi and away you go. It really isn't complicated and I have never had any problems with it. As mentioned above mine is also flashed to do EQ mode and I added a cheap wedge so now it has multiple uses.
  17. I have never used one of those but I use this regularly. It is goto and tracks, operates off AA batteries which last for ever and operates via a smart phone app. https://www.firstlightoptics.com/skywatcher-mounts/sky-watcher-az-gti-wifi-alt-az-mount-tripod.html BAHHH you beat me to it John, haha
  18. if you wqanted the sybony zoom then its apparently available hee https://www.ebay.co.uk/itm/SVBONY-1-25inch-Zoom-Eyepieces-7-21mm-8-24mm-10-30mm-FMC-Metal-for-Telescopes-/283962379034 However i would check first
  19. happened a few times, one recent where i set up my truss dob back to front. Any idea how hard it is centering a star when the finder is under the scope
  20. That Bresser looks a very nice starter version of the 150 OTA. If the friend can push the budget, then I would go for that everyday. However it only comes with one eyepiece, a zoom on top might be needed. https://www.amazon.co.uk/gp/product/B00EL5XU9S/ref=ox_sc_act_title_1?smid=A2QGSSHY6RX5FN&psc=1
  21. Welcome to SGL, I haven't read all the above replies so sorry if I am repeating. Both the 130 and 150 dobs are great starter scopes. There is a slightly better light grab with the 150 of course but either will suit you and your son initially and maybe for very many years. With the right attachment you could attach your camera and do very short exposures of the night sky but I would say no more than a few seconds at most. As others will have said dedicated astrophography is both more complicated and much more expensive.
  22. why not get a mount that is goto https://www.firstlightoptics.com/computerised-goto-astronomy-mounts/sky-watcher-az-gti-wifi-alt-az-mount-tripod.html that can be converted to EQ https://www.firstlightoptics.com/skywatcher-star-adventurer/skywatcher-star-adventurer-equatorial-wedge-white.html You need to flash the mount but it is simple, I did the same. It can be controlled from your computer. Downside I don't think it is a tracking mount but I have managed imaging planetary of 15 minutes without drift. Just a thought.
