Smithysteve Posted February 24, 2015 Share Posted February 24, 2015 Really useful stuff Mick thanks, I am at moment sharing and comparing UHC and Oiii filters with an Astro buddy at the Mansfield and Sutton Astro club to see which is the best, but nothing on this scale. First time I made out the veil neb was last year through an Oiii and 12" dob. It was incredible and was a wonderful moment for me - I could not see it without the Oiii. I have the Skywatcher UHC filter, but not tried it through my 10" cat yet on the Veil neb. Its high on my list though! Cheers Steve Link to comment Share on other sites More sharing options...
+Doc Posted February 24, 2015 Author Share Posted February 24, 2015 Yes a 12" dob and a O111 filter are a match made in heaven. Link to comment Share on other sites More sharing options...
BAZ Posted February 24, 2015 Share Posted February 24, 2015 I find the UHC is able to bring out detail without darkening the view too much. Try them both, and see which one works for you best. Link to comment Share on other sites More sharing options...

It certainly saves a bit of time informing us what filter/filters is best to use on which object. There are a few more objects than you might think that can actually benefit from a h-beta filter.

+Bino-viewer Posted March 16, 2018 Share Posted March 16, 2018 What are the differences (if any) between a UHC filter and a CLS filter ? I have a lot to learn with filters. I've only ever used an ND (out of my white light solar kit) to dim the moon a bit I have a HB but it hasn't impressed so far. Link to comment Share on other sites More sharing options...

CCD filters won't work visually or vice versa. Have a look at the light curves, they are quite different animals... +Bino-viewer 1 Link to comment Share on other sites More sharing options...
+Bino-viewer Posted March 17, 2018 Share Posted March 17, 2018 So the CLS is for imaging only and not designed for visual ? Heres an interesting thread re CLS filters : https://stargazerslounge.com/topic/81054-astronomik-cls-eos-clip-filter-test/?hl=+astronomik So i'm guessing i need a UHC / and / or / an Oiii ?

Tweedledee Posted March 17, 2018 Share Posted March 17, 2018 (edited) I've never heard of anyone using CLS filters for visual. I think it is just horses for courses, sensors have different sensitivities at different frequencies to the human eye, so the filters need to be different. Personally I find visual filters a pain to use because the view is quite odd and difficult, and you lose a lot of star brightness, but sometimes the right visual filter just makes certain nebulae jump right out at you. I have 2" UHC, LPR, OIII and H-beta in a 5 position filter wheel with one hole clear, so I can instantly switch between filters. Recently I got a filter slider which does the same job but is lighter weight. The OIII and UHC are the most useful.
