It may be worth bearing in mind that this forum is open to all ages, experience and ability levels.

It costs nothing to be positive and polite.

Yes we are not all rocket scientist's....and weren't born with telescopes on our eyes.

Hi Mark,could you give a bit more information..ie scope,mount ect, is it a dob you are using now.

Coma cluster, around 5 hours but really needs a lot more time,

102ed

533mc pro

l-pro.

Just over 5 hours on this, really need a lot more time but with weather not easy....

102ed

533mc pro

l-pro filter.

Finally moved enough towards the west for me to get a chance, albeit for only around 15 mins before it's gone again so grabbed the small window to get a shot.

What was your individual sub length..... cracking image.

We update, new flats bias and dark flats..

Did you let APP decide the integration settings automatically?

If APP chose to not reject anything, or chose too high a sigma for hot pixels you would see this.

Is this what you mean.

To my knowledge yes,I have took new calibration frames to see, interestingly run only lights through APP ant the artifacts were showing..

Looks odd and you never seen this before. It has a pattern to it. Makes me think it is not ordinary hot pixels. Maybe it could be some electronic interference with the USB connection to the camera. Have you changed anything with regard to cabling?

I did re connect the leads just before the session....

Hot pixels? Have you used darks in the stack?

Thought that, confused why I never seen this before.

Is this OSC data or separate LRGB channels? If it’s the latter, do the separate R,G and B stacks look OK?

OSC

looking at the frame edges the stack has been dithered? What calibration frames were used for the stack?

Used flats and bias only.

Just run this through APP as always but never seen this before......any ideas.

That's what I see.....

Hello all, I am using a 102ed doublet that a believe is fpl 51 glass and want to know would there be much of a difference with a similar scope with FPL 53 glass.

I have added pic for example.

Brilliant.... can't wait to see the full 10 hours if under 4 gives this.

Maybe a clean is in order🥴🥴, will do that tomorrow.

For some reason I never had a problem but I have just installed a reducer and I am now getting some of the dark darker streaks as seen in the left bottom corner, the third one is just the non stretch image.

Images are just raw shots in Asiair.

Hello all, never really knew if my flats are good or bad, any ideas please.

Tia Paul.
