Re: WTS : 9mm Widefield Eyepieces: Explore Scientific & Stellarvue Optimis

I was hoping to use these for solar eclipse chasing, but they are just too bulky. I've only used them maybe twice or thrice? Do contact me asap so I can bring them back to Singapore. Yi-Zen P.S. Obviously I can't spell "Optimus" properly... Stellarvue Optimus 9mm: S$300 20230702_041807_SV...

Re: 29Apr - Spectacular Active Regions and Proms

Thanks. Airconvent. The Sun is undergoing Solar Maxima where we are seeing more solar flares. This, I believe is one of the reasons for increased interest in the Sun lately 😄

Re: iOptron HAE 29 Strain Wave Gear Mount

The ioptron support staff are based in the US. So their shipping quotes are from the US store, and not the China store. Thanks for the nice summary table above. I am waiting for the HAE43 to appear in Asian shops. Hi Lawyer, You are right that the iOptron Tech Support are based in the US. Over the ...

Re: iOptron HAE 29 Strain Wave Gear Mount

Hi Alfred. It weights only around 3 kg. I used their online calculator, probably not accurate. It's good to know the actual shipping fee is more reasonable. Thanks 🙏 Oh, I see. It is good to check with the support staff. I have good timely advice from John (tech1@ioptron.com). All the best. Alfred

Re: iOptron HAE 29 Strain Wave Gear Mount

Their HAZ31 mount is very attractive, since I do mostly visual astronomy. It will be perfect for my use, without burning a hole in my wallet. Just curious on the actual shipping fee you paid, Alfred, if you don't mind sharing. IOptron is quoting around $500 USD 😅. I've shipped a 13 kg equipment to ...
