Winter Diffuse Nebulae thru Image Intensifier
#5671817 - 02/10/13 05:08 AM Attachment (36 downloads)

Hi All. Snappped the pics below through a Gen 3 thin film image intensifier with a 50mm f1.3 lens and a 12nm H-alpha filter. Every shot is at 2X magnification. Exposure time is 1 sec. Took these from Mount Pinos, Calif where the temperature was in the teens. The live views with the eye looked very similar to the pics. Enjoy.

First up: Barnards Loop:

Any comparison without the Ha filter ?

How dark and transparent were the skies? Go and get a copy of Reiner vogels Sharpless observers guide, there are a lot more that are worth a try though Auriga and Gemini. Without the filter you'd not see much at all, you need to give the intensifier only the light you want and nothing else for maximum contrast.

Cheers

Here's one more shot. This is the Flaming Star nebula and IC 410 in Auriga - same settings / equipment as previous pics:

Thank you jdbastro! Great pics. What you have posted is exactly what I have seen with my IIE and small but fast lenses/scopes. When I first saw the Meissa Ring I was confused as I had not even heard of it before. The Seagull Nebula is new to me. Gotta look for that.

Ahh, the Seagull Nebula. Also called Gum 1 and usually attributed to Monoceros. Yes I have seen that one with my IIE about this time 4 years ago at a nice dark spot on the SC beach.

That's great! Do you have to be at a dark site even with the Ha filter to see this stuff with the IE??

Which tube and housing are you using for these images,they look great, very envious.

Many of these are visible within the city, but the finer details and edges won't show as well. For example, Barnard's Loop might be barely visible whereas the Rosette should show pretty well. I can't really see the Meissa nebula within the confines of Los Angeles. In brighter skies, a narrower H-alpha filter provides better contrast - I prefer a 7nm filter in this case. Good luck!

I used a fairly high grade ITT gen 3 thin film tube (SNR > 29, EBI < 1) to get these pics. The housing is a Micro Monocular from Night Vision Depot.
