SM40 FD and Tal/PST active region 11/08/2018

Dear All, Got some sun today so had a couple of quick sessions. Started with the Tal/PST mod and concentrated on the active region. 100 frames stacked from 1200 frame SER captured with the PGR G3. Later had a gap so got the SM40/ 62mm Petzval combo out ( alt-az and drifted to get rid of NRs ). 100 f...

Re: 14th July Ha and CaK sun

Wonderful detail Stu. Are you near the sea? Seeing is rubbish lately here on the Pennine margins.
Could of course be due to the new obsy not being as porous to the wind as the old one .

Early session AR + proms - rubbish seeing 14/July/2018

Grabbed a quick session this morning, but seeing was awful. Tal/PST mod + PGR G3. Could only get 50 frames to stack in each case. I hope it is better where you are.

Re: Sun July 8th

Franco, It is always a successful session if you manage to get anything worth showing. It is all good practice. I have been following the threads on DS adjustments. I have enough problems adjusting the single SM40 on a slightly longer scope. I think my arms must be shorter than the average T-Rex :-)...

Re: Sun from 30th June and Noctilucent clouds

Sorry I am a bit late to the party and have just got round to catching up.
Beautiful set. Love the detail you get and the limb sharpness on your FDs.
I don't think I have ever seen any noctilucent clouds let alone imaged them.

I always like your full disks. Can I ask what was wrong with your etalon? How did it become misaligned and how did you correct it ?

They are lovely, I would not have thought you would get so much detail from that amount of cloud.

Re: AR and prom 11/July/2018

Thank you all, much appreciated.
I don't say this often but I am pleased that it is raining today.
Hopefully it will dampen down all the local moor fires, but I hope it is clear where you are.
Gives me a bit of a chance to clean all the image train components at least.

AR and prom 11/July/2018

Got a so-so session this morning spoiled by a dirty sensor. I have cleaned up the images as best I can. I am also beingplagued by some reflections that I can not eradicate. Might be time to go back to the drawing board and invest in an external D-ERF . 100 images stacked from SERs captured with Tal/...

Re: July 4th SM40 FD not much going on ...

Thank you All. Alex, I have been experimenting with varying the gamma on my captures. My current setting favours disk detail but makes it difficult to bring out the prom details without a lot of noise. I will need to experiment more to do a better ( more complete ) job.
