flat black paint

HQA Sun, 10/18/2020 - 14:29

I just finished painting a light-tight enclosure and used the Krylon 4290 Camouflage ultra-flat black paint.  I've found it to work well in the past.

I also have a bottle of a special flat black acryllic paint that Gary Walker gave me: Blk3.0 from  A similar product (Black 2.0) is available from the Stuart Semple brand through Amazon and other online stores.  I've also used the Testors EPM25-2549 flat black marking pen when doing things like blackening filter edges.

SBIG CFW-8 filter wheel and Astrodon filters

I have trouble screwing Astrodon filters all the way into the CFW-8 filter slot. While I was able to work some of the filters into the filter slot, most of the time, they won't go in.  As a result, my filter wheel won't turn.  My question for those that use the CFW-8 with Astrodon filters is how were you able to load your filters into the filter wheel carousel slots?

Second photometric filter

Hello all,

This is my first post in this forum. I have a question and I think people here can help.

Me and some friends have a telescope at E-Eye, which we use primarily for astro photography. We also have a photometric V filter, which we lately have been using for performing measurements of variable stars (in particular V1391 Cas). In our filter wheel, we have an empty slot, and we are planning to purchase a secondary photometric filter to fill the last slot.

I recently purchased this low-lux IP camera for $51. It is an easy plug-and-play with PC, and comes with the free CMS software to allow display on the computer. It has good 1080p resolution, is full color and weatherproof, so easy to install and use, OOTB.
