After a few months of getting used to my new 8 inch beast, I decided to start astrophotography (luckily today is Black Friday in most tech shops in my country). So I decided to drop the idea of buying a DSLR and started thinking about getting a webcam. The thing is that I want to try deepsky AP, so i was wondering, is there a webcam that could get me good results for DSO AP? Don't worry, I don't want anything too fancy because I'll be happy with entry-level images. (i saw some nice Andromeda pictures with 20GBP cameras on this forum so I'm confident that it would work).
My budget is ±100 GBP, which in my opinion is more than enough for a good webcam . So... is it worth getting a webcam? Or is there something better? Should I wait and raise more money for a DSLR?
Thanks a lot!
I would like to share my first picture ever posted and the first real picture captured with my Tecnosky 80/480 APO FPL53 Triplet OWL Series (not counting the test shots for "first light").
This is IC 1805, also known as the Heart Nebula, taken over 4 nights, under my Bortle 5 home sky.
Total integration time: 8h 52m 20s.
Here are the acquisition details:
Mount: Sky-Watcher NEQ6 Pro
Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
Camera: D5300 astromodified
Reducer/flattener: Tecnosky 4 elements, 0.8x
Guide-scope: Artesky UltraGuide 60mm f/4
Guide-camera: ZWO ASI 224MC
2020/10/07: Number of subs/Exposure time: 1@60s + 80@90s. Notes: No filter, Moon 70% illuminated
2020/10/13: Number of subs/Exposure time: 2@60s + 11@180s + 1@200s + 12@240s. Notes: L-Pro filter, no Moon
2020/10/27: Number of subs/Exposure time: 59@180s + 1@240s. Notes: L-Pro filter, Moon 88% illuminated
2020/10/28: Number of subs/Exposure time: 48@180s. Notes: L-Pro filter, Moon 93% illuminated
Total exposure time: 31940s = 8h 52m 20s.
Pre and post-processing: PixInsight 1.8.8-6.
Unfortunately, the best out of the 4 sessions (no Moon and L-Pro filter) was also the shortest one. But, after waiting for 5 months for my telescope, I couldn't pass up the few clear skies opportunities I got since it arrived, Moon or no Moon.
Here's a link to the full resolution image: Heart Nebula (IC 1805)

I'm selling these 2 filters since I'm getting a mono astro cam. The filters are barely used and in perfect condition, no scratches, no fingerprints, not even dust. They are both amazing filters, probably the best investment I've made. I've attached some images
taken with these filters, using a 100$ celestron newtonian, a 250$ Canon 500D and the infamous AVX. Also attached are images of the filters showing their perfect condition.

Recently I bought a ZWO ASI178MM for planetary/lunar/deep-sky imaging and last weekend i had clear skies so I was able to capture videos of the moon in two panels. I have already processed the videos in AutoStakkert, I used 3x drizzle because I intend to print the image so now I have two 120MB TIFF images that i would like to combine in a two panel mosaic. I tried doing it in Hugin, a free panorama stitcher but the program crashes due to the file sizes being too large. I have searched for tutorials on using DynamicAlignment in PixInsight but it seems to me that i'll need a reference image to be able to create mosaics in PixInsight. Is there any way to go about this, I feel like this should be a pretty straightforward job but I am not very experienced in PI so I would really appreciate some advice.
I tried using DynamicAlignment as you can see in the attached screenshot but the result was just a cut version of the target image, aligned perfectly to the source image. It would be perfect if it didn't cut off the lower part of the target image.
