Hey could ypu recommend which package you went for as I'm seriously considering this. Just alot of money to chuck in all at once shame he does not do a subscription 

Know worries just come back into the hobbies after along time away and this actually came up in a Google search and I wanted to see the video

Thank you Grant really appreciate it.

Hello where is the location of this video

Hello All I'm interested to know what everyone else does when guiding. My question is is it better or not to bin the guide camera. I have a QHY5 ii with a finder guider set up and ST80. Was wondering if it is better to bin the camera or not and what are peoples thoughts on this

Think it's the same tripod on my AZ-EQ6 and they're on the inside on mine (I think 🙂 ). Better there so they don't get kicked anyway

Thank you for the clarification 

Hello I have just purchased this mount from FLO and can you tell me when you opened the box with the legs in it was leg extender clamps facing inwards like in my picture.

Excellent work and nice and natural with wonderful colors 

I'm currently trying to process a version of the rosette nebula. I have not been able to do any imaging over the last 5 years and when I stopped I just purchased a CCD camera and Pixinsight. The images I had taken I did not bin my RGB and now wondering after seeing your image to maybe bin the colour from now one as the green and blue channels seem to have the most noise. Was it difficult jump to go exclusively to Pixinsight ?

There is a lot of information but have a look here:

https://pixinsight.com/forum/index.php?threads/for-beginners-guide-to-pis-imagecalibration.11547/

Also check out Adam Block's WBPP video series. These should give you all you need to know at least for now and probably for a long time....

Thank you I will check these out

I suppose what I'm trying to get at is the Dark frame with the bias frame subtracted should be as expected and from what you are saying it is ?. The light and dark were exposed at the same times and temperatures.

Ian

Ok thank you for looking I'm also on CCD not CMOS

Ian

I'm following guides on how to process images in Pixinsight and they are all going in the direction of calibrating the dark with a bias in image calibration. 

This is one guide I'm following: Light Vortex Astronomy - Tutorial (PixInsight): Pre-processing (Calibrating and Stacking) Images in PixInsight

But something does not feel right

Ian

Could anyone please advise on potentially a issue I'm having. When I stack my dark files I find everything looks good as expected.

 MASTER DARK.xisf

But when I apply the bias to the dark file in image calibration the pixel value (I think) goes to zero and the dark is not completely black.

MASTER DARK_c.xisf

Can someone tell me if this is expected, the above dark is also auto stretched. The dark was taken at -20C five minute exposer on a SX TRIUS 694 CCD. I have also included the master bias

MASTER BIAS.xisf

Regards Ian]

Thank you I will have alook at that

ok so in the master light there is 2 dark lines but in a single sub there is only one dark column which is very faint. I wonder from dithering every 2 frames has added more lines into the stacked image and made them more pronounce. I will have to look into pixinsight as there is a feature to remove columns/rows just need to learn the software more. 

Hello Olly

thank you for helping me I have also attached a single sub. Seems there is only one column on the single sub.

My master bias shows the defect much more clearly

For stacking I'm using Pixinsight but I'm learning how to use it. I have been away from this awesome hobby for over 4 years due to conditions where I use to live.

I don't think its the white lines but the dark linein the middle of the 2

Hello I'm trying to process my images with a CCD starlight xpress 694 mono camera. On my images I know there is a dark band running down the picture from top to bottom.  The issue is for me that when stacking I cannot seem to remove this band. I'm dithering and using darks, flats and bias frames and still the band remains. am I doing something wrong as I was under the impression the vertical lines were removed by calibration files in the bias frame.

I have attached a master file if someone would not mind having a look for me.

excellent detail my favourite night sky object

Wow I'm imaging the Rose 🌹  myself I just would love to have a image as good as that nice.

This sounds very interesting indeed, I will have to give this a try.

First Light Optics you provide out standing service, i was looking for a finder base for my c9.25 scope so i could use my finder guider from my ED80 to the C9.25 and was not sure which one to buy that would fit so i emailed FLO, i had a email back to me in a matter of mins with the link to there web site for the correct one to use, i placed the order well into the afternoon friday, so i was expecting to receive my goods maybe monday, i was pleasantly suprised to find that when i finished work saturday evening to find my parcel at my house, this has to be the best service i have ever had so thanks so much for the service you provide and i will be looking forward in purchasing my next lot of items in the near future .

here is my very first image

thanks for this post being looking for somethink like this for age's thanks jgs001 will have to give this ago
