Re: Acheiving parfocal direct projection (APS-C) on the Wild M420

I recently purchased a Wild M420 and Scarodactyl informed me that it was even easier to attach my Canon M50 mirrorless APS-C camera to the existing photo tube than that described here for a DSLR. That because the sensor is closer to the front of the camera. All I needed were the following. Both inex...

Here is a fancier? model 500. Looks pretty interesting; and it has the 15X UWF eyepieces too!

Re: Breaking the baffling B & L Balplan buffalo.

These Balplans sound very interesting. I noticed the strong similarity of the stand with my SZ7 R Stand, which seems very nicely designed and built. I also noticed that many of the Balplans on eBay are missing their condenser, I wondered why that was so. Cheers!

Re: AO Triocular vs Beam Splitter

Well I had some success I think, but I really couldn't recognize the concentric rings per Phil's guidance. I'm not sure if I was focusing the telescope at the right level, but I did move it up and down. Probably there but I just didn't see them. I pushed ahead anyway by adjusting the field diaphragm...

Interesting and thanks Phil. One last question on the nosepieces. I connected a 110 nosepiece to a model 10 scope and while it seemed to fit, it didn't properly align with the field diaphragm (too far off to center it). And the single bolt I loosened didn't travel in as far as it did on the native n...

Hi all, I was also interested in Zuul's question: "On a loosely related note, I was wondering about tube lens compatibility. If a 410 Trinocular head popped up, how far off is the correction when used with the older 34mm objectives?"

Anybody know? Thanks.

Re: Carpenter bee

Hi krame, thanks and welcome.

1) no, just take a pic, shift focus a bit and take another until top to base of subject is in focus. I use helicon focus for stacking.

2) he was deceased; I only work with insects I have found dead by natural causes.

Interesting, I'm still confused about the difference between these 2 adapters. I also purchased the $450 one and then returned it because I thought it was (almost?) identical to the less expensive one. Interested what others think. Thanks for the post and comparison!
