+RonC Posted February 17, 2018 Share Posted February 17, 2018 (edited) I am using my Canon 1000d with a CLS clip filter fitted and a SW Skyglow 2" filter to clear some of the AP from my garden location. Would I be better off fitting a 2" H Alpha filter instead and what are the pro's and con's of these filters please? Thanks Ron Edited February 17, 2018 by Ron Clarke Spelling!

philjay Posted February 17, 2018 Share Posted February 17, 2018 You would still need the cls filter Ron. I tried it a few years ago with my 1000d. It should work ok. Link to comment Share on other sites More sharing options...
+RonC Posted February 17, 2018 Author Share Posted February 17, 2018 Thanks Phil, I would reckon to leave the CLS filter in the camera anyway Link to comment Share on other sites More sharing options...
+Graham Posted February 17, 2018 Share Posted February 17, 2018 Interesting that you would leave the LP filter in as a 12Nm and up ( or is it down ) to say a 6Nm HA filter should block all LP out as standard. Link to comment Share on other sites More sharing options...
+Graham Posted February 17, 2018 Share Posted February 17, 2018 In fact giving it further thought Why are you using two filters in line that are designed to take out the same sort of light transmissions. The more glass you put in front of the chip the lower the resolution ( if that is the correct word ) reaching the chip and the more problems you can create for yourself.

+RonC Posted February 17, 2018 Author Share Posted February 17, 2018 Your right, never thought of it that way, next session I'll remove the 2" filter and see what the result is like! Still think I might get a H Alpha filter though.. this one maybe? www.ebay.co.uk/itm/Skys-the-Limit-2-Night-Sky-H-Alpha-Premium-High-Transmission-filter-with-data/162360506964?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 Link to comment Share on other sites More sharing options...
philjay Posted February 17, 2018 Share Posted February 17, 2018 When I played with the dslr and Ha I used a 12nm filter and it suffered with LP. I experimented with the CLS filter on it as well and it reduced the effect considerably. When using my Atik I always use a CLS for the same reason. I have mistakenly left both the clip in and the 48mm cls filters in when using the dslr and wondered where the photons went Link to comment Share on other sites More sharing options...
+Graham Posted February 17, 2018 Share Posted February 17, 2018 At 40Nm it is very very wide. I use a 6Nm filter with my Atik.. Personally I would go for a 12Nm filter with your Canon. Admittedly it will cost you a lot more money but the difference will be like chalk and cheese. I have a 1.25 12Nm filter here if you want to try it Ron before you shell out loads of money.

+RonC Posted February 17, 2018 Author Share Posted February 17, 2018 Thanks Graham, not sure how I could fit that in the image train? I realise it's a wide filter but I didn't too narrow a filter and I have to watch the pennies! maybe I'll wait for a S/H filter to turn up? Thanks Phil, glad you found your photons again!
