Title: Rosette Nebula 080311
Post by: Fay on Mar 09, 2011, 16:21:25
QSI, 7nm Ha filter, 0.8 fr, ED80, Captured in Astroart, 11x600 sec, darks, flats bias, stacked DSS, processed in PSCS
Planned on 20 subs, but was so tired & the clouds came in anyway.

Quite pleased with it, after all my scenarios

Sky was so bright last night.

QuoteSky was so bright last night.

wont make that much difference as you were narrowband imaging.

Very nice Fay - Looks like you'll be keeping the QSI then  :(

When will you be adding the colour  ;)

Very nice Fay.  The conditions were even bad for NB imaging last night so you did well.  You need to get that flattener sorted out but I wonder why you have distorted stars towards the top right rather than a more even distribution around the edges.

I was going to say that Robert, my guess is the flattener is not done up, or Fay has cross threaded the QSI or the adaptor to the QSI.

So, Chris, do you have two adapters connecting the flattener to the QSI??

Hi,

I have an M48-T thats the correct length.  So it goes Flattener-M48-T-QSI.

Could also be the weight of the camera on the focuser, maybe it needs a bit more tension.

Very nice crisp detail Fay.  You seem to have sorted all those initial problems out.

Onwards and upwards.

Very nice 2nd light!  That's a very sharp Rosette.

Thankyou Mark, Carole, yes I am having a rest tonight. At least I have made some headway.

Thanks Chris, I will look that up, it is not the one that Ian sent me

That's super Fay. Keep persevering and people will think you bought a second hand Hubble camera!
