Yesterday under the full moon I was able to get 4 hours of Rosette Nebula. 2 hours of Ha and 2 hours of SII, but guess Rosette is not very good with SII ...
You should take O-III, it's kind of strong in a centre of Nebula. S-II is weak, as you mentioned. Btw. A very good tool in PS is "Shadows and Highlights" Try...
Hi guys, Some people are taking the female bayonet from a Pentax 6X7 close up tube, those close up tubes are available in sets of 3 on a popular auction site...
Thanks for the tip, I will try it right away I will take OIII when the moon goes down. Taking OIII in full moon would have been impossible Clear Skies Maurice ...
Is anyone using H-beta or NII filters? Would love to see some samples with these not often used images. NII looks like a nice alternative to make three color...

Hey David, Your Pentax adapter is beautiful. The Pentax Macro Extension tube you mentioned is a great option. The profile of the female bayonet is slim,...
Hello Maurice, You can see this : http://www.oamp.fr/search/search.cgi?q=nii Some objects on Ha NII and OIII. It is curious to see some differences. Nicolas...
Richard Crisp has some very good images with N[II] and HeII there arent many using HeII (Helium 2, 468nm) helium works best in very hot objects, like planetary...
Bob, I’ve been checking on this Vixen VC200L and looks very interesting. I may be going for a mirror scope since I get more aperture per dollar paid. ...

I have an R200SS and a buddy has the VC200L. Both of us get boxy stars due to the large spider vanes and are considering switching out the spider. There are...

I worked on this object during some clear skies this week. I had to shoot with the full moon also. I put in alot of data, but it was really hard to get any SII...
It just did not get as sharp in the Ha data. I replaced the image, but I did not use much noise reduction on the image. I need to work on the collimation again...
