Subject: Re: vote by xxx.xxx.48.182 By: Anonymous (xxx.xxx.17.21) Date: 09/21/2005 01:20:09 am PST >Used on an 80mm f5 short tube refractor. No visible reduction in false colour on bright objects (D. Hinds ad. says it will remove false colour). Belts on Jupiter slightly enhanced. Not tried on moon. Little difference with regard to skyglow - may reduce it a little but also dims object being viewed. Spend more money - I wouldn't buy again! Hmm strange i've looked on the David Hinds website and it makes no mention of it being a CA remover. Which off course you wouldn't expect to be because that was never it's purpose anyway. It has to be used in conjunction with the Baader Fringe Killer to remove false colour. And there's no filter in the world that will remove all the false colour from an 80mm f5 achro. Only really effective on the f8 - f10 models. And as for little difference on Skyglow...no way!!! I think you forgot to screw in the filter! Subject: Neodymium Filter By: Anonymous (xxx.xxx.207.199) Date: 03/27/2006 09:46:32 pm PST When using this filter with an ETX 90 I found little removal of general skyglow. However, when looking at the Wild Duck Cluster only 10 begrees above the horizon is did mkake a noticeable increase in contrast. The reason to get this filter can be summed up in one word - Mars. Looking at Mars in the favourable apparition in September 2005 using the Neodymium filter resulted in a massive increase in contrast. The darker areas really stood out whilst still retaining Mars natural colour and not excessively darkening the image. Page 1 of 1 | ||||||||
