what sort of IR block filter needed?

Posted By Greg Bradley

I have a ToUcam 840 Pro. I see a lot are using an IR passband filter. Can I ask which type is suitable for the ToUcam?

Thanks,

Greg.

Here's a photo of the framing of an observatory I am building in a rural NSW location 3.5 hours south of Sydney. It has dark skies you dream about! Almost zero light pollution and quite mild temps in summer. 722 metres altitude (approx. 2300 feet). Panoramic views in all directions especially vertically at night!

I got a 219mm steel pipe with 4.8mm thick walls and made a hole 600mm (2.5 feet) with a hole shovel. It is concreted in and levelled. The frame is 3 metres x 3 metres with a flat slide off roof I designed. I intend to install a sliding window as well and clad the walls and roof with colorbond steel.

Total cost should be under $1800 I'd guess.

Lagoon nebula, dark site, Sbig 2000XM, HaRGB 120:90:72:60 secs.

William Optics 80/480 fluorite triplet.

I took a lot of shots but this is a sample combine of one set of them. More shots can be median combined and get more signal but not sure for how much gain.

I'd like some comments here. The core was a bit burnt out but the exposures were only 120 secs Ha and less. F4.8 with a TV .8X flattener/reducer and resolution set to medium (I think that means 2 x 2 binning). So the camera was very sensitive. It is quite a bit more sensitive than a DSLR.

Camera at -26 degrees C.

Paolo's website is infected

A warning that my computer became infected with a Casino software from visiting Paolo's business website. It is trying to take over my computer.

I got a message I needed to download some software to visit his site and when I clicked on yes it installed a Casino software that takes over your internet explorer.

Tak Setup

Posted By Greg Bradley

Setup my new rig today to see how it all fits. FS152 fluorite doublet, William Optics 80/480 TMB fluorite triplet, Tak NJP mount, Tak diagonal. Robin Casady 14 inch saddle.

I also set it on either of 2 piers- 1 in my backyard observatory the other in my dark site observatory. The 2nd setup is RCOS 12.5 on the NJP.

With Sbig 2000XM or Nikon D70 or ToUcam/Sac 7b for planet work.

Nice to have. Its part of the fun of astronomy.
