Determine RA/DEC Co-Ordinates
Posted 17 December 2013 - 06:25 PM
I have an idea of doing it using SGP and the "Centre Here" function to get an idea, but is there another way to determine it?
My reason is that I may have discovered a faint planetary nebula in Cassiopeia and I'm trying not to get too excited about it until I can verify/validate it further.

I would use MaximDL's pinpoint platesolving feature to center on the spot, and then look at the solved coordinates of the image's center. I don't know of a way to just click on an area of the image and have it show the coordinates... though that would be neat.

Another way is to use a program like SkyTools 3 Pro that has a very deep limiting magnitude (roughly 19). Then find a star very close by. That will get you very close.

but... the labels only cover the bright objects.
but given the labels you can then use SIMBAD to get into the area. no need for any software to download.
this is how i identified some mag 22 galaxies in a deep image i took (using rented equipment).

Who can I talk to next to tell me that I'm 100 years too late or possibly (long shot) even better news ... ?

It was confirmed that my planetary nebula had already been discovered and credited to a fellow amateur astronomer in France that has an additional 13 discoveries to his name! Incredible!
The reason why I could not find this in any of the online databases because it is currently documented in an unpublished professional database known as the IPHAS catalogue. It has so far been credited with 300 new PNe discoveries in the Northern Hemisphere and the MASH survey has discovered an additional 1000 in the Southern Hemisphere. The IPHAS catalogue is slated for publication sometime in 2014 - did not receive a solid date.
In the meantime another database is slated for publication in February of 2014 of all known PNe discoveries to date (3300 total).
The good news is that his contacts in France have requested that I focus my processing on this planetary nebula because it contains data that they can use for further analysis/research.
Though I don't get credit for the discovery, this has most certainly opened up a new door for me in this hobby and has sparked a huge interest in performing discovery work.
Time for a new CCD!
Ah yes - ~coordinates!
Located North of star TYC4052-824-1 and East of TYC 4052-1260-1.
You *may* be able to see it in the DSS catalogue's red plate, but is quite faint.
The official designations: IPHASX J030421.3+621802, LDû 14

What CCD are you considering?
Posted 21 December 2013 - 09:53 PM
Terry I am considering the FLI ML3200 camera (NABG) due to its extremely high sensitivity in both Ha and OIII - ~90% and ~65% respectively. The downside (outside of another freaking bloody expensive CCD) is its small field of view - @F3.65 it is 1.5 x 2.2 degrees.
I never thought of getting into the aspect of discovery, or research work because of the perceived disadvantage we would have, but after seeing 14 discoveries by an amateur definitely gets me excited about where any of us can go with this.
