Hi Fergus, This might be interesting, I tested both the BE and E Plan and others: https://www.closeuphotography.com/4x-lens-test/part-one-4x-for-less-than-100-dollars <image snipped> Robert Hi Robert, Yes I've been reading your image test threads recently. The little BE 4x did very well, impressive...

Hi, I emailed BW about these two objectives in early February. I was quoted US$490 per lens, plus US$80 for TNT couriers. I purchased the 2x objective but haven't used it yet (still building my rig, and also had to order an adapter for the threads). To perhaps put other potential purchasers at ease,...

I wonder about internal reflections, especially with so many sections in the tube (some telescoping no doubt).

Thanks Rik, that SBS article had a much better explanation.

Cheers...

Hello All, In our news recently there was a 'new' microscope based on helium. I don't even pretend to understand the science behind this, but I thought some might find the development interesting. http://www.abc.net.au/news/2016-05-16/world-first-scanning-helium-microscope-unveiled-uni-of-newcastle/...

One question - which objective exactly are you using? In regards to the 200mm lens - I picked up a mint, literally perfect brand-new condition, 200mm f4 Q Nikkor for under US $70 on ebay. Something like that might be ideal for your 200mm tube lens. As I understand it, infinite objectives use the cen...

Hi Fergus, yeah I downloaded the pc and the mobile app on my laptop using an android emulator but I guess it just doesn't send the signal out in the emulator version, so no luck there unfortunately. I got it to work on my phone but it doesn't serve as much of a screen really. The kindle works now t...

For the remote control to work you need the Sony app "smart remote control" installed in the camera and "playmemories mobile" in the tablet or device. Run the app on the camera first and then the device will spot the camera. From memory there's a default setting for the transferred images to be smal...

...I haven't found much information so far about how to size heat sinks for LEDs. I assume, not all of those 36W get converted into heat. But I'm not sure how much power has to be actually dissipated by the heat sink. Cree (just as an example) offers detailed thermal management documentation for th...

Drat! Just today on eBay I purchased an objective from this seller... fingers crossed...

Andy that's a great price - less than I paid from Optics Planet (once postage is included). Well done!

I'm glad I bought mine when I did, knowing this.

You might try Coherent Scientific located in South Australia. They were selling the scope complete with the objectives, maybe they can supply the objectives on their own?

Cheers...

Hi Andy, did Opticsplanet change their policies? I'm in Sydney and bought my 4x and 10x BE objectives from them in recent months.

Nice image! As another lurker/beginner I haven't posted anything, nor taken anything this good.

What is it? (without meaning to appear stupid)
