Lyra to Cygnus and Hercules: The Lynds, MW, MDW, MBM, and the Mel Bartels Nebulae

#1

Post by j.gardavsky »


Hello all,

this is a report on the binocular search for the high galactic cirrus with its streams, and for the large ionized hydrogen and molecular regions on:
2020: May 19th, 21st, 25th, 26th; July 21st, 22nd, 23rd, August 5th, 6th, and 8th
2021: June 1st, July 11th and 30th
under the Bortle 3 to 4 skies from our backyard in Erlanger Oberland.

A documentary sketch is here,
Lyr Cyg Her for publish.jpg

The most famous among the HII regions in the constellation of Lyra are possibly the “Horns of Lyra” MW8 (Mandel Wilson), and the most difficult object in this area of skies.
The first successful observation has been through the 15x85 binoculars with the 8.5nm H-Beta filters. Once seen, the 12nm H-Beta filters have shown these thin bent bands, reminding the horns, as well.

A repeated search for the faint fuzzies in central Lyra has shown a few condensations and bands, which have been confirmed according to the MDW H-alpha sky survey, https://www.mdwskysurvey.org/recent-hig ... c4135eaf1f by David Mittelman, Dennis di Cicco, and Sean Walker.

Checking the eastern Lyra, unexpected has been the visibility of two streams pointing from Cygnus towards the parallelogram of Lyra. The first has the large LBN 225 (210’x50’) in its core, and the second has the large LBN 244 (420’x90’) in its core. Once found with the 10.5x70 binoculars through the blue(RGB)CCD filters, these both streams could have been later followed through the 8x56 binoculars as well.

The Mel Bartel’s objects between Lyra and Hercules have been identified both with the blue(RGB)CCD filters, and even without.

A new stream Nu-Delta Herculi into the Mel Bartels Keystone Nebula has been found.

The last object in this observing program has been the Sh2-73 loop with its LBN 105 and LBN 106 segments, separated through the 15x85 binoculars with the blue(RGB)CCD filters. This Sharpless nebula is the brightest part of an extended glow, which may belong to the galactic molecular gas MBM 40 (Magnani, Blitz, Mundi (1985)).

Thank you for looking and reading,
JG

As a rule,
I hold the 15x85 binoculars in my hands.
When the objects are low above horizon, then the 15x85 will be mounted on a tripod.

Clear skies,

Outstanding! Congratulations on the observations and the VROD award.
... binoculars with the 8.5nm H-Beta filters. ... according to the MDW H-alpha sky survey, ... blue(RGB)CCD filters ...
Thanks also for showing what is possible. I assumed that filters would not work with direct observations, only photography. Now I know.

Best Regards,

H-beta is my most used filter for visual observation. OIII is runner up. I disbelieve the reports that big aperture scopes are needed. I use them in my 80mm fracs.

Hello all,

the problem with the H-Beta filter are the filter ratings lists, not the H-Beta filter per se.
The filter ratings lists prefer the UHC and OIII filters,
which is partially true when you put on the list of the DSOs those ones, which can be best seen through the UHC and OIII.
Admitted, there are quite a few nebulae, which can be seen through an OIII filter even under the full Moon, but that list is worked out very fast.

Besides the planetary nebulae, which are typically candidates for the OIII filters,
I have in my observing log book notes on about 400 galactic nebulae, and most of them have been best seen through the H-Beta filters.
And another 400 galactic nebulae for the H-Beta filters are still waiting on me.

Still half way on my journey,

I agree. The rating lists for H beta filters are irrelevant to my observing reality.
