Anybody else out there?
Would like to know anyone else's suggestions for target(s) to capture. I'll post my own a bit later.
Cheers,
Ray
Hi, I'll now do this in a couple of chunks. One explanation for earlier is that I inadvertently touched cancel by mistake instead of submit! Alternatively often on this tablet touching the Submit button does not work and if you then back out of the post it gets lost. Part 1 As previously mentioned I will probably have to submit our list in an email so will need to know some details first. What is a bit problematic is that the list of targets I received of those currently queued up, doesn't mention the integration times. I really cannot estimate how many hours in total need to be captured before any of these, our bookings, can be started I'm afraid.As you say, Veil and California are a good starting place given the fact that they are progressively sinking lower in the West as time goes on. I would go for narrowband as they are amazing in any variation on the Hubble palette. The general opinion seems to be that when shooting NB you go for longer and fewer subs as NB images are read noise limited. The Pier 14 recommendation on the website is for 600-900 sec for bright objects. So perhaps 600 sec to start with on each of the three filters? Say 15 subs for each to see how it goes? I think we need some experiments to figure out what works for this rig. Centering the veil complex in the frame I get current date coordinates of RA 20:38:41 DEC +34:37:07 The California Nebula will fit the frame using 'official' coordinates, but centres in the frame a bit better at RA 04:04 39 and Dec +36:28:40The Veil nebula and California nebula ought to be our first submissions due to their positions. Now with a lot of targets there will be choices with regards to narrowband and/or broadband imaging. Please indicate what your preferences are for each one we submit. For any booking on a public pier the exposure length and numbers are required. For any narrowband booking I'd probably stick with the maximum exposure length of 300 seconds. For broadband this would need a bit of investigation first. This leaves the number of exposures. I'd be happy to do what I do for my own bookings and base them on images others have done and have provided the capture data. This I adjust according to the optics used and image scale to give an approximation. A mosaic of the Cone and Rosette region would make a fantastic project and in the next post I'll suggest how we undertake it. These are all only my suggestions based on a little knowledge and experience, so please don't hesitate to make your own.
