+Graham Posted November 22, 2012 Share Posted November 22, 2012 (edited) I decided to test the new secondary mirror dew heater tonight. Grabbing the chance of the clear sky I decided to have another crack at M1. This is a combination of 46 subs of 120 seconds at ISO 800 and 11 subs of 60 seconds at ISO 1600. Stacked in DSS along with 11 darks at ISO 800 and 3 at ISO 1600. Light processing in PS 6. Taken using the Helios 200 Newt with an unmodded Canon 350 D Full size image at -- http://db.tt/SSaG1poU I have had another go at this this morning. full size -- http://db.tt/lQUAODds Edited November 22, 2012 by Graham Link to comment Share on other sites More sharing options...
Daz Type-R Posted November 22, 2012 Share Posted November 22, 2012 Nice one Graham, how did the dew heater perform, I tested mine out last night (indoors) and it worked a treat, after about 30 minutes at full power, I could feel warmth in the secondary (not using full power out in the field, this was just a test)?

andyboy1970 Posted November 22, 2012 Share Posted November 22, 2012 Very good for an unmodded camera. I'm surprised you need a secondary dew heater, mine has never misted up. Link to comment Share on other sites More sharing options...

Andy I don't know if its down to my location but I suffer badly from it. My obsy is tucked away in a corner surrounded by trees so gets very little air movement. Its great for wind protection but I fear it increases my dew problem. Link to comment Share on other sites More sharing options...
