back in the game - with some new (to me) targets

Hi all, just posted a "help me" post so thought I better stump up with a contribution as well.

I've been in an out of astrophotography since the 80's with hypersensitised colour film and my own T-max B&W processing...more recently in the digital age mainly planetary and web-cam stuff, but have been off the boil for years.

Enter COVID and to entertain myself more at home bought a decent mount and started planetary again... just out of interest thought I'd see what my old canon dslr and little zenithstar 66sd could do from heavily light polluted suburbia and was amazed... really how is this magic possible stacking short exposures!!!

a couple months on a it's now an espirit 100d and asi533mc camera and some LP filters.

Have taken "the usual" for this time of year, but noticed a couple of nebula in scorpio I hadn't really imaged before, the Cat's Paw nebula and Lobster Nebula... again amazed I hardly knew these were lurking there not far from lagoon, triffid, omega, eagle etc... and they'r actually quite large and interesting targets.

Anyway here they are for your interest, advice, abuse whatever takes your fancy :-)

Lobster just 2 hours of 300s subs
Cat's Paw 4.5 hours over three nights mis of 180s and 300s subs

Welcome back
Your getting back into the hobby at a time where technology is growing at a rapid pace , there’s new products and software popping up all the time
Nothing wrong with a old DSLR , I started AP just over 3 years ago, borrowed my wife’s 10 year old Canon 600D , bought a 6” newt and was hooked
Lovely images by the way
Well done !!

thanks Martin, it's wierd how well the old canon apsc dslrs do, i have a un-modded 600d that I have some nice shots from and a modded 450d bought from a forum member which actually sold me on the benefits of a dedicated astro camera... it's very competitive with my astro camera, but I like the convenience of having a dark library setup for specific times and temperatures.

I see you have the ASI2600MC... I was very tempted by that camera which has the same sensor characteristics as my ASI533 but with a much bigger sensor size. I've ordered another APSC sized camera the ASI071MC pro (fixed problems that were in "cooled" version) in the end, partly as it's cheaper but also wanted a pixel size difference to the 533. Not as sensitive as the 2600, but hope it works out ok.

added another hour and twenty and reprocessed Lobster

brought this up to 3hr 20 with another nights imaging and reprocessed... not a lot more detail but here it is. Hmmm looking back on original thinking I make have over-done it trying to extract something more here... think I prefer the first one :-)

thanks for the encouragement peter. that's something else I'm getting used to ... incredible you can add to old pics ...couldn't do that in the film days ;-)

I think I may just have over-processed this a bit. Next time I add some data will try and keep things a little more "subtle"
