Hi all for sale is a 90mm Ha Lunt scope constructed from a 50mm Lunt Ha scope with a 4mm blocking filter and a celestron 90mm achro refractor upper tube.There is an additional ERF filter on the end of the Lunt etalon(the filter is a 50mm Baader 35nm Ha filter).
The scope can be used in mono mode (which I prefer) or it can be used with binoviewers(need a small extension tube to come to focus).The scope was constructed about 12 months ago and gives very detailed views of the suns surface and proms.Scope comes with tube rings,but no eyepieces.
Scope cost around $2400 to make,so asking $1500.Would also be willing to trade it for a SW 120 ED scope or a 4 inch Tak refractor plus a cash payment.Would prefer to sell locally here in melbourne(so you can try it out),but willing to sell interstate at buyers expense,thanks Nick.
