ERF For Sale

Post by MapleRidge »

Hi all...

I have started to clean up un-used items around the observatory, and have an ERF that is redundant now (inherited this 100mm with a filter system I bought, and had one to begin with).

This is a Daystar 100mm ERF, which I believe was originally designed to fit an off-axis SCT filter and has had a color added to allow it to fit over a 4" objective. The filter measure 100mm in diameter, and can fit up to a 115mm objective/dew shield. There are no set screws to hold it, but the nylon type material would be easy to drill and tap if needed.

This is their older red RG30 material, and you supposedly need an IR cut filter mounted ahead of the etalon if you are using PST type mod. I imagined with my Lunt mod, and Daystar Quantum through this ERF (no IR cut) and it worked quite nicely.

There is a bit of loose dirt visible in the pics, but I can clean it up before shipping.

I was thinking I'd like to get in the $300.00 US for this, plus shipping, but open to reasonable offers. Daystar lists new filters this size at $500.

If anyone in the group is interested let me know and we can sort out the details, and I'll do a bit better on the price for anyone in the group. Click the e-mail button below to get in touch.

Thanks,
Brian
