Nice photos.  What is your set up for the Ring (telescope,  eyepiece) ?

Thanks. PVS-14 with the Televue 55mm +67mm converter/ 12" dob

First image is the Eagle Nebula.

 

Cool how much you can see with NV!

With so few stars visible to me as even a guide in Bortle 7-8 it can be difficult with a few DSO to find. I'm almost certain this is the Lagoon, but let me know if it's not (Omega, Eagle etc).


That’s the Eagle Nebula.

Wowww. So, I still have not even seen the Lagoon yet! My roof doesn't allow my line of sight to catch it. I will have to wait another week or so. Pretty sure I can get enough sky in. I wouldn't want to miss that one.

I'd also not overprocess the images. A mild Gaussian blur with small radius (just enough to get rid of most high frequency noise) and then a single unsharp mask is going to give you better results with less artefacts than the rather aggressive unsharp operations you've used now. Of course tastes do differ, but I mind a bit of noise less than I mind obvious processing artefacts.

I have a cheap 30mm Stellarya eyepiece I bought because it fits the PVS night vision. The other one is the Televue 55mm with 67mm converter.

I'm beginning to wonder if that cheap eyepiece is causing alot of unsharpness and degradation from what  I see before i post process. I think I may stop using that. I know when I used the barlow it was terrible.

Guess i will stick to the 55mm only from now on. Wish I could enlarge and crop but it's nothing like the DSLR resolution.

The artifacts appear to be more from the eyepiece before processing from what I see. You've encouraged me to do better. Thanks.

I can see Lagoon nebula in one of your photo. The one x1 with the roof, it is the lowest and brightest one, very close to the roof.

I meant to post these here a while back, some images from an observing session back in June. 

 

Bortle 5, SQM about 20.3 according to the light pollution map

12" dob

55mm plossl w/67mm converter lens.

Handheld iphone 11 

I'm still learning my way around taking pictures, but I've learned some just from these shots.

Sorry, I forgot camera settings. Pretty sure 1/3rd sec. No averaging. Will do that next time though. PVS-14 55mmTelevue.67mm converter.12" Dob.

Milky Way-680 long pass/7nm H-Alpha for other one

M13: 30mm Stellarya eyepiece (longpass)/55mm with longpass

Ring N.-H-Alpha/55mm Televue
Comet: Longpass/55mm Televue

Need to work on it some yet. The 30mm Stellayra seems to exhibit artifacts that are not due to sharpening or motion blurring. Going to look more into that.

I doubt this, but asking anyway. Is their any alternative to getting the highest resolution possible besides a cell phone? Don't know much about equipment, but what about the movie cameras used for tracking? I don't have a tracking mount, but are those of any use without a tracking mount?

Sure would be nice if you could buy just a camera if that's all you need rather than a new cell phone just to use that program on it.

Can exposure be locked on a cell phone? When I tap screen the yellow square appears and I adjust exposure, but if I move the camera slightly, the expsosure re-adjusts automatically.

I think having a device like the FoneMate which holds the phone in place is pretty much necessary if you want to use it for imaging NV displays - I only do handheld grabs and have noticed a big difference between the pics that come from that vs those taken by folks using the FoneMate (or other such devices).  I think in some of these devices you could even substitute a digital camera for a smartphone if you wanted but I'm not an expert on that.

I am using something similar to the phonemate. Figured out how to lock the exposure/focus. Tap, then hold down on the square.

Wow, I just got on my home computer and that shot definitely lost something from my phone to the site. It doesn't even look this bad when I view the site from my phone. The original shot on my phone has nice tight stars.

Cell phone shot of 2 stacked images of M27 with a 32 inch.  One image was no filter the second image was with a 7nm h alpha filter.

Was just out with my N.V. scanning saggitarius region and i found what looked exactly like the ring nebula?? and then another which looked identical to the dumbell nebula. I had no idea any of those planetaries were in that area.

Wish I knew what those two were.

Hi Pat, 

M57 (the Ring) is in Lyra while M27 (Dumbell) is in Vulpecula. So what you saw in Sagittarius are other Nebulae.

Yes, I know. I am describing it looked like the "ring nebula". I figured out what it was. ngc 6369
