This post relates to the object Simeis 147, aka sh2-240 and Spaghetti nebula. The fact that objects can be called different things may result in inadvertent duplicate submissions. The only thing we can do is to point out at the time when this happens. 

To read more on this and since I don't know how to link to other posts :(  you'll have to navigate there yourself. Look at page 2 of the Pier 14 advisory post. The relevant post is #3741 posted on October 19th but the discussion starts from post #3718. 

Nothing has been collected as of now but given the total integration time were both to be completed, I think now is a good time to revisit this. Thanks to Hoi for pointing this out in the first place. 

Cheers, 

Ray

Hi Steve, 

This section of the forum was a good idea, however, not much use if topics don't get read or are ignored. Would you consider being an arbiter in this instance and make a decision. The details of each submission are - 

First submission calls for 8 hours additional oxygen data, while the second for 10 additional hours in both hydrogen and oxygen, 20 hours in total and 28 hours overall! 

I could complicate matters even more by submitting a third for say, 8 hours oxygen and 2 hours hydrogen as a compromise, but then they'd be 38 hours. :(  I appreciate that this should not be your job, and, we're all entitled to submit whatever we wish, but this is an exception I believe. 

Cheers, 

Ray

Hi Ray

I presume we are talking Spag Bol  nebula ?


To be fair its a bloody dim object so collecting a bit more is not a bad thing, I suggest I amend it and add the extra and we see what we get as I doubt any member will be upset at getting a decent amount of data on this object as most people seem to take 50 hours plus of data :)

Hi Steve, 

You are correct as to the target and I'll gladly leave it to your experience as to how much extra we may need. You say it's a somewhat dim object, not as bad as the Squid and the new Titan nebula I hasten to add. :) 

Thanks for doing that, 

Cheers, 

Ray

I just combined the plans and added some more data to that plan. If you feel it needs more than I have done just holla :)

Personally at F3.6 I think it is enough but you all may feel different LOL

Before I forget to mention and I will alter the relevant posts but I have altered the priority system. Its made a huge difference but I felt OIII needed to go surther up the pecking order

0 = HA SII
1 = RGB OIII
2 - Luminance

Cheers

Hi Steve,

Finally found the time to produce a couple of images for your consideration. These are stacks of data from the original Spaghetti capture, then  pruned down using the results from  the Normalise Scale Gradient script in Pixinsight. After stacking they were then only  cropped and stretched. The Ha stack represents 51 x 300 sec exposures a total of 4 hours 15 minutes. The o3 stack is from 44 x 300 sec exposures a total of 3hrs 40 minutes. A lot of the o3 frames captured were rejected. Some additional Ha data is desirable but I'd had thought an additional couple of hours plenty. With regard to the o3 an additional 6 hours should suffice.

Given the high rejection rate with the o3 data I'd go for 10 hours of o3 to help deliver the 6 hours after rejection of sub-standard subs and 3 hours for the Ha, a total of 13 hours.

If anybody has any objections to the 30 hours currently submitted being reduced to 13 hours, then please reply. In the absence of any objection within the next week would you please amend that job again Steve. Apologies for any inconvenience. :)

Cheers

Ray
