Ferrero 6 faint planetary nebula in Cassiopiea HOO (Pat Rodgers)

Ferrero 6 faint planetary nebula in Cassiopiea HOO

Only discovered in 2013 ( Nov), by Laurent Ferrero and confirmed in 2014 (Jan). I first saw this on Astrobin's IOTD by Sacha Schueller on his 16" homemade newt. A fantastic image and worth a visit. I love a good planetary so had a google. There's an image by J Shuder on his 9.25 which was the first coloured picture and the fantastic Hanson astronomy image on a 24" scope taken in New Mexico's dark skies, well worth a look. A year on from seeing Sachas IOTD and Cassiopiea rising I found this in SGPro's sequence file after taking me last Abell in the constellation.

Wow this is faint! The second faintest I've tried to capture. Kronberger 61 shows nothing in a 900s sub, at least Fe 6 has a Ha fleck to show it's there.

Managed 4 hours on my first visit 2 each in Ha and OIII ( nothing shows, but rare a planetary like this has none.) As it swung past my limit I finished the night on Abell 12 in Orion, as a filler.

Last night I managed another 5 hours. In-between sessions I checked Astrobins search filter and saw Chris Sullivan's superb IOTD from late October, this is amazing and only 64 hours worth :-0

enough wind bagging here's my humble effort of Ferrero 6, Fe 6, PN G129.6 + 03.4 the bright star nearest the Pn is BD+64 263 or SAO 12045 if these help in SGPro's framing and mosaic wizard. Mr Abell would be miffed at missing another one. Looks akin too his number 6 to me.

Original: 2hours Ha and 2 hours OIII. Will add to this.

B

Description: A stretched version of 9 plus hours HOO, hard to improve the PN without ruining the stars etc, for me.
Didn't like this but it shows what's there. So made a blend of this with my final image.

C

Description: Here's the blend less PN, stars are better ( always naff in nb anyway.)

D

Description: Single Ha 600s sub with PI's STF stretch applied, SGPro's stretch isn't as harsh, buggers still faint.

E

Description: The Ha 2 hours stack from Armistice day, g'auld bless 'em all.
Pn shows up nice, the OIII stacks has similar showing.

F

Description: Ha stack 5 hours 20 minutes de-convoluted and used as a luminance. The difference between 2 hours and 5 is very noticeable in the faint Pn. The 2 hours is a STF whereas this is manually processed.

G

Description: Finally my final image which is under processed and used in the blended version. I like its transparency.

H

Description: Clouds so re-process time.

I

Description: Just a 2021 reprocess of the old data.

J

Description: Old data revamped using all the RC Astro's gizmo's. Stretched using GHS. A vast improvement on previous efforts.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
