Svbony 1.25" Double Helical Focuser Telescope lens - £23.40 Sold by RetevisDirect and Fulfilled by Amazon

This will definitely be a niche deal, but hopefully it will help a fellow astronomer. Between 10% and 15% voucher discount on the double helical focuser with adapter (choice of SC… Read more

Non rotating. The tube will only move up and down. Never used it in a telescope. I have one on a finder scope and the other one in an OAG. Theoretically you should be able to get it in a telescope, assuming you only use 1.25'' eyepieces.


I’ve got something similar for my telescope which I find tricky to find focus with. The helical focuser can be used as an additional fine focuser (either immediately before the eyepiece or in my cast between the tube and diagonal) so I can get a rough focus using the main focus knob and then use the helical focuser to get it sharper. Not sure if this is a rotating or non-rotating version - makes a difference if not using a straight-through eyepiece as a rotating one can move your eyepiece to poor position.


Just starting here.... can't figure out what use this would be on a telescope? Moreso for a finderscope?


Tried one of these but it blocked all the light in my 70mm Teleskop Service ED for all eyepieces. Thankfully it was a present - I didn't spend any of my money on it, but it cost £103. So this is defo Hot!... (y)

Right, even though I have other small telescopes, I don't have a GOTO mount, and I don't have a Schmidt-Cassegrain, so I decided this was an offer not to be missed, and maybe I could get rid of some of the other 'scopes. It arrived the other day. Seemed very impressive. Well made, solid tube, mount, and tripod, and, as I aligned the guide red dot finder, obviously very good daytime optical performance. And very easy to move around slung over the shoulder. So I was very excited to check it worked at night. And that is there where it all went wrong. Wifi connected fine. Lined it all up on the first guide star, OK. Lined it up on the second, OK, Lined it up on the third, "alignment failed" Over, and over, again. Beggar. Tried again two nights later. Same result. Absolutely frustrating. I was all for returning. Then last night I tried again. This time I leveled the mount with a spirit level, and I changed the new AA batteries I had originally fitted with a different brand - I don't know what the voltage was when I first tried them, but they were sub 12V when I checked before using the others - which showed 12.6V. And bingo! It aligned. So I don't know why it didn't work before but I reckon it was voltage, or, more likely in my mind, the tripod level. So if you did buy one and are having troubles - then try those. Oh and there is a firmware update for the mount - though I haven't tried it since updating.


In the past.


Where is this price ?


It was the same price yesterday, think the posted price is non prime delivery price


Showing up as 339.48 for me today, so slightly cheaper

read the whole thread and im still as confused as when i started reading for those more knowledgeable in these things, what is the best one to buy for a newbie which is not more or less a toy, that has a large capacity battery (rechargeable battery) so one does have to charge it too frequently and has a good range and circa £50 max (as i will need to buy 2) ? (confused) ...also, can use it without a licence plse.


8-10 miles would really only work if you were across an estuary/valley, or at least one of you was higher up. You might be able to talk with roof antennas, or using HF (the wavelength where CBs are at the short end), so it becomes far more expensive, & more a hobby rather than just a way to speak). With the longer wavelengths, signals can bounce off a layer in the sky, but I've never taken much of an interest in that aspect of radio, and stuck with something to use almost like a mobile phone when suits.


Sorry, I was half expecting a "but electric scooters are illegal" type discussion kicking off. If you want to know anything else, feel free to ask.


Thanks for the response, I probably won't bother then, don't know much ahout this and was originally hoping to have a fun way of me and a friend communicating, she lives about 8-10 miles away :) Probably won't bother now. (we don't live in cities)


Apologies, predictive keyboard got the better of me, fixed now. I wasn't in any way taking issue with what you're saying, merely trying to figure out what the query was behind "but why?" Thank you for all the info, I've had a thought at the back of my mind about getting something like this for a while but wasn't quite sure what to get, where to start, etc.

Celestron 71008 SkyMaster 25 x 70 Binoculars - £70.10 @ Amazon

Now showing as £99, but one seller is listing them, new, (on Prime) at £70


Very true. I prefer my 8x42 as they have large field of view, are brighter, sharper and easier to hold.


I bought them 3 times from different sellers and each pair was badly out of collimation. Fortunately they are exceptionally easy to collimate. Excellent optics.


I own the Celestron 15 x 70's and they needed collimating. I own 3 pairs of bins along with a small scope, 7 x 50's, 10 x 50's and the 15 x 70's. I prefer the 7 x 50's as their easier to hold but these come supplied with a tripod mount which helps keep them steady (you need a tripod though.) Collimation was easy, best done in the daylight but all it involves is using a micro screwdriver to align each eyepiece. When done right, the quality really improves. Quality has went up and prices have come down. This is a good price.
