Re: Off-brand eyepiences in Microstar IV (410)

Thanks apochronaut; i'm also interested in using 15x eyepieces in my microstar 410. Can you confirm that the CAT 184's will fit in both the narrow eyepiece tubes? Thank you!

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

hi sreynolds: yes, i stacked a number of pics using HeliconFocus. It works well and is easy to use.

The Wild macroscope does have an iris that can increase the DOF at some expense of resolution. These were taken with the iris wide open I think.

more citric acid crystals

Inspired by Rob Berden's recent post, I tried melting citric and ascorbic acid crystals separately. I had good luck with the citric but trouble getting a clear melt with ascorbic. I then mixed the 2 and may have success but I will have to wait to see. I liked this citric acid pic. HNY to all!

Thanks Pete. I have a Gemolite Mark V with an AO mount that I would like to attack my B&L SZ7 to. I knew it was a long shot.

Adapter to mount B&L StereoZoom Pod to AO StereroStar stand?

Hi all. Has anyone ever heard of or built an adapter that would allow a B&L StereoZoom pod to be mounted on an AO StereoStar stand? Thanks.

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...

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!

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.

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!
