Interesting new filters from IDAS

[Space Oddities]

I came across this blog post from Hutech, the company behind the IDAS filters. Apparently some new filters are coming, that work with ZWO cameras only, and only some models.

They can be screwed directly in front of the sensor, as shown on the pictures below.

Quote

Following 5 models will be available within a week or so.

• NGS1-Z : $199.00 (introductory special 10% off)
• LPS-D1-Z : $199.00 (introductory special 10% off)
• NB1-Z : $199.00 (introductory special 10% off)
• LPS-D2-Z : $199.00 (introductory special 10% off)
• HEUIBII-Z : $199.00 (introductory special 10% off)

 

• 1.1mm thickness, so adding a filter makes camera’s flange back 17.14mm +/- 0.5mm
• A filter frame is held by the t-threaded male portion. So the required length is critical. The tolerance for the variation of its length is 3.9mm to 4.3mm. 4.0mm is quite common. So basically you don’t have to worry about that much. Hutech provides a spacer ring with no extra cost if it is a bit too short.
• An extra benefit to users who are looking for 1.25″ sizes. IDAS doesn’t make 1.25″ sizes for above 5 models. (LPS-D1 used to be available. But recently discontinued and sold out). So if someone was looking for 1.25″ sizes in one of above types, this is a good solution.

This is the limited time offer as the introductory price.  Keep in mind, NB1 should be really attractive price. This is the worldwide campaign. So the same offer should be made by your local dealers shortly.

Interesting. I would like to see the transmission curves for these filters. IDAS are generally good quality LP filters, but if the zwo cover glass isn't as good, what are the chances of the combination causing unwanted reflections?
