Insight Observatory comes to the rescue again-clouds and storm,. This is from the 12.5" RC, Namibia, about 20.2 hours, LRGB.

Thanks. The challenge was not to overdo them.

Thanks!

The dust lanes are bullies in this galaxy--They are like tentacles of s submerged nonster, rising and thretening as I beat them down like wack-a-moles. Data from Insight Observatory remote 12"RC. LRGB.-about 25 hours I think. As with most data sets I get from IO, it required substantial effort to tame. Paerts of it are oversaturated, and other parts pale. The dust lanes control all. It is very difficult to process this galaxy without darkenbing the dust lanes too much.

Thank you!

Data from Insight Observatory. I’ve decided to limit my data dalliances to targets that I can’t image due to their declination. This is from a system that shoots at 1.3”/pix, but I binned it 2x2 due to the size of the image.

Finally, a wider field image of this target that doesn’t scream out to be cropped. I wonder how far the extension reaches at top.

Thanks, P.I!

Thanks S!

Thanks Mack

Thanks

I wasn’t satisfied with my previous Rosette experiment where I used TOA Ha and FSQ OIII and SII to make a SHO image, then inserted the TOA Ha as a luminance. This time, I mage a SHO image with all FSQ data (Ha, OIII, and SII), then inserted the TOA Ha as luminance. It made a big difference. The palette was much more balanced. I still used Bin 2 (which I usually do with TOA data that is .79”. I still plan to collect OIII and SII with the TOA. I am confident it will improve the final image, especially if conditions are good. TOA 130 about 10 hours Ha FSQ 106 with .6x reducer, about 5 hours each of Ha, OIII, and SII

Interesting framing. It gives it a real 3D look

Thanks Alan.

Thanks, sunshine….like a ray of….solar radiation on a gloomy day!

In general I agree. But in this case, my question pertains more to the data then the final product. Would the data be better if I collect equal amounts of OIII and SII with the TOA. So I refer to image potential not necessarily the final image that I manage to create

Thanks Spock (or should I say evil Spock?). Wondering if all TOA data would be noticiably better

Due to endless nights of cloud, rain, wind, fog, etc., etc., ect., I decided to experiment with my recently acquired Ha data, as I am won't to do. I used OIII and SII data from the FSQ 106 reduced (318 mm) and Ha data from the TOA native (well reduced by .01x). Since I always use Ha as a luminance in SHO images, there is quite a bit more Ha influence in the image than OIII or SII. As there is quite a difference between pixel scales of .79" and 2.46", I had to upsample the OIII and SII to achieve alignment. The image is displayed at .79", which represents Bin 1 for the TOA. The big question is would it be worthwhile to collect OIII and SII with the TOA. Opinions on this are most welcome. TOA 130 with .99x flattener and ASI 1600 (Ha: 50 300 sec); FSQ 106 with .6x reducer and ASI 1600 (OIII: 47 300 sec; SII: 54 300 sec)

Don’t forget the pack of dogs at his heels and the other members of the menagerie!

Thanks. I would be too. But last night it was supposed to be clear with good seeing until dawn. And the seeing was amazing, I was getting subs of ngc 1491 with FWHM of 1.6”. I couldn’t wait until the Rosette rose. But then, after 10 subs of < 2”, the clouds rolled in. I only got 10 additional subs, but the FWHM of the stack dropped by .5”! It’s amazing what good seeing will do to an image. Now it’s hard to be satisfied until I get 100 subs under good seeing!

I finally can see the fossil footprint. Many images taken with large scopes concentrate on the brighter part of this nebula. But to understand its name, a wider FOV is needed. As most of the signal is in the brighter region, widefiled shots don't seem to be that common. A fairly tricky image to process due to the dynamic range between the bright "heel" and the much fainter "toes". Seeing was a rare "good", resulting in a FWHM of just under 2". Ubfortunately, the Moon was near full and closer than I would have liked to the target. I hope seeing is decent when shoot the OIII and SII. Maybe I'll shoot RGB` TOA 130 with ,.99x flattener and ASI 1600. 54 300 sec Ha. Bin1

Thanks, Olly Wise words, as usual.

I have always wanted to do a close in of the center of the Rosette, but the closest I ever got was cropping wider FOV images. No matter how hard I tried, it just didn't fool anybody. I hadn't planned on doing it this time, but clouds didn't leave me much choice. I started imaging at midnight, and out of the targets available, decided on the Rosette. Seeing was only fair, and I got a late start, so I will be adding Ha to this while the Moon is up before collecting OIII and SII. Themn, maybe RGB. TOA 130 with .99x flattener and ASI 1600. 3nm Ha: 40 300 sec Bin 1 I posted 2 versions, a darker and a lighter becuase I can't choose.

Thanks , Doc and No! I’m not sure. Normally it would be easy to do it and if it didn’t help much…..”oh well”. But seeing as I get only a few nights a month to image, and even less for broad band, I hate to lose a night (or two) on a fools errand.
