  1. As Mars is drawing closer I was thinking if it's worth getting a 5x Barlow for my setup? It's not really designed for close up planetary but wanted to see peoples results with a similar setup. Scope: ES 102mm APO Camera: ZWO ASI224MC I used Astronomy Tools with my setup and a 3x Barlow I already have and a 5x Barlow. There is a bit of a difference but Mars might still be too small. Thoughts? Thanks, Stefan.
  2. Hello. I have been processing an LRGB shot I got of the Trifid over 3 nights. It was a challenge to capture as the weather was different on all three nights. The first night most of my photos were useless which was a bummer. Stacked the photos in DSS (Lights, Darks, Flats and Dark Flats) then processed in PixInsight. I noticed a bunch of my stars look very red. I am not sure if they are hot pixels or red stars. In the past I used the 'detect and clean remaining hot and cold pixels' option but it screwed up the stars so I have had that option off ever since. I might try select it and restack. I have attached a picture of the weird stars. Do they look like hot pixels? I combined a total of: ZWO ASI178MM-Cool + ES102 Triplet - 74 x Lum - 37 x Red - 38 x Green - 65 x Blue - 25x Flats per LRGB = 100 Flats - 25x Dark Flats per LRGB = 100 Dark Flats - 52 Darks (3 degree variance) Thanks, Stefan.
  3. For those down in Melbourne, Australia this is why the clouds rolled in this morning. Looking forward to giving this a go and comparing images with and without the filter. I might need to invest in a cloud pollution filter now
  4. I have done this in both Photoshop and PixInsight. PixInsight has a good workflow to do it, Photoshop a few more steps involved but easily done. Nice image by the way, great detail. What scope and camera did you use to capture Mars?
  5. Hey mate. Sorry, I can't answer your question. I wanted to ask how does astroberry run on the Pi? I use an Intel NUC for my main rig but thinking of building up a Pi for my portable setup.
  6. So, I have been doing some research and reading on various websites and forums in regards to LRGB and Narrowband filters. I am currently using the ZWO 31mm LRGB and H-Alpha filters in my rig. These are the first filters I purchased due to getting into monochrome imagine and the price point was perfect at the time. I have been using them quite a while and now starting to look at the next step. I havn't actually used the H-Alpha one yet as I am concentrating more on LRGB imagining for now. Based on my research I have compiled a list of low, medium and high end filter brands. I wanted to get peoples opinons on their experiences using them and why they liked it or disliked it. Please correct me below if I am wrong. Low-End - ZWO - Optolong (possibly mid?) Mid-End - Astronomik - Baadar High-End - Astrodon - Chroma Obviously low end is where I am now so I will be looking at the mid range filters. Also is it worth investing in 2" filters? This would be upgrading to a 2" filter wheel. So basically: Q) What is a decent mid range LRGB & Narrowband filter kit? Q) Is the 2" upgrade worth it for future proofing and when would it beneficial? Thanks!
  7. OK so I worked out the sizing issue. My reds were captured with 2x2 binning which is quite embarrasing. I must have accidently clicked the arrow to change it and didn't even notice. I was scratching my head thinking why he hell is it only the red channel lol.
  8. Thanks for the reply mate. I forgot to mention I was using SGP. My images are normally 12,584 KB. I had 8 Reds only 3,150 KB which is really strange and are still .FITS. I will go through all the data I captured and checl.
  9. Using a ZWO ASI178MM-Cool with LRGB filters. I was going over the data I captured and the red images look to be too bright (similar to the luminance channel). Is there a way to verify within the image properties what colour the monochrome image is? Want to make sure they weren’t captured using the luminance filter. My images are normally around 13mb and noticed a few came out only 3.5mb. Possible corruption? Thanks!
  10. I am checking over some past images and the Green/Red channels look to be crisp whereas the Lum/Blue look a bit blurry.
  11. After I stack one of my colour channels I noticed the final image looks a bit blurry, like its out of focus. The original image looks a bit sharper. I loaded the processed image into PixInsight and the data looks good. Is this because the processed shot is shown in it's linear format or is there a process setting I am doing wrong? I am stacking 15 Lights, 38 Darks, 25 Flats and 20 Dark Flats for the BLUE channel. Below is a snippit of the image before processing (lighter) and after processing (darker). Thanks!
  12. Yeah I had a look at the Astrodons but holy crap that is way out of my price point. The Astronomik 6nm looks to be a good price. I am currently using 31mm filters. If money was no object I would go all out and get 2" but I need to draw the line somewhere!
  13. I think I have finally nailed it. After watching many tutorials and creating my own workflow I have come up with the below. Still a lot more to explore with PixInsight but am happy with the result. I found the key is to make the L channel a little brighter for the detial to pop.
