Re: Brotip : Telescope Export Restriction at Amazon.com lifted

thats very attractive offer. C8 at this price. Does lazada offers return if OTA is damaged. I have done it with amazon, but my returns with lazada is messy - the seller has to agree for return/refund else it gets rejected.

Want to borrow - linear binoviewer

Hey astro peeps, I have been using standard binoviewer for some time and absolutely enjoy the views. Recently linear binoviewer are gaining a good attraction. If you have one, could I borrow one for a coupe of days, before I decide to buy one for myself. If you happen to have the kasai 0.66x reducer...

Re: 3D printing mounting rings

there are certainly some designs available on thingiverse which can be adapted. but more importantly wanted to get some advice from local folks who do 3D printing, spool, printer model etc.

3D printing mounting rings

I saw a plenty of videos about astrodymium, hyperpod, astrokraken (i hope I got it right), but the shipping etc is a bummber. I have been thinking of getting a 3D printer for som...

Re: Comparison between 102achro, ed100apo, mak127 SkyWatcher

very nice comparison. I think the ed100 doublet is fantastic scope. though I also loved the orion 120ST. despite being an achromat, it was a fun scope, fast at f/5, short and easily to grab and setup. but I had better views through the ed100 doublet of the luna. I have pondered a number of times abo...

Re: Portable battery power (star tracker, asiair, guidescope)

for a star tracker like skywatcher star adventurer, I have used an anker 28600mha power bank. Found a usbA to mini usb (thats the port on star avdventurer, a usbc- power plug (one of asiair pro) and it worked fine for some 3-4 hours. very portable as well. I used the same for az-gti and asi air pro ...

Re: Comparison between 102achro, ed100apo, mak127 SkyWatcher

interesting.. I had a different experience. The ED100 f/9 doublet have such good views of jupiter/saturn and moon that I was tempted to upgrade to sw120ed. but I havent tried the 5mm bundled eyepiece. I use a 10mm UFF or celestron 8-24mm zoom most of the time and with them the views are excellent.
